I will teach you how to repair your computer! The laptop turns on and off immediately
The very first thing I plugged in the power adapter and tried to turn it on, it of course started up, all the indicators and fans started working. But I didn’t see the picture on the screen, so I climbed further.
- Tried starting laptop without battery
- Disconnected the RAM strips in turn
- Disconnected hard drive HDD
- Disabled the Wi-Fi wireless access module, by the way, read how to enhance wi fi here
But all these options did not help me, although it might be useful to you, because after doing everything as I say the laptop can work. But I did something else. I took the laptop apart, got to the matrix and just disconnected it, then I reconnected the matrix connector to the video card.
After that, the laptop turns on and immediately turns off, but not that immediately, the picture on the screen has already appeared, which means that the problem has been found. After assembling the computer, I again did another test, but it was not there, the laptop stopped loading again. So I had to take it apart and see what was wrong.
Having disassembled the laptop, I saw that the plug coming from the matrix to the video card was NOT clearly standing, so I corrected it again, I assembled the computer and it all worked with a bang! As you can see, there was a common and banal reason for the connector, with which I fumbled for an hour and a half just because I did not know what exactly the reason was. But you are lucky, you just repeat after me and you will succeed. If what I wrote did not help you, then let’s see what else they write about this.
That’s all guys! Now you know why the laptop turns on and off immediately. In gratitude, please press the social buttons. Thank you all and good luck!

The laptop turns on and off immediately. The answer is!
Hi people! Yesterday an acquaintance said that his laptop turns on and immediately turns off itself. Of course, I could not refuse him and asked him to bring him to me for diagnostics, but first I found out exactly how it turns off. Because if the laptop turns off after a couple of seconds and immediately these are completely different things.
If it turns off immediately, then this means a problem with the BIOS, maybe some BIOS signals occur. Well, if in a few seconds it can mean anything. Let me tell you what happened to a friend’s laptop and what I did.
The laptop turns on and off immediately. There is an answer! 31 comments
Author You have described the whole process of work perfectly. One problem. you need to have a specialist like you, at least in the phone book! I’m afraid to cope with disassembling and assembling a laptop, I can disassemble it.
The laptop can also turn off from many other factors. For example, overheating, or too much RAM. Or errors in Windows.
I say right away. Check the charger. The voltage usually comes out of the conductors. If it’s okay then check the batteries. They dry up and give a load to the charger. Proto-computer does not have enough voltage
That’s right, Max! Due to overheating, the laptop may also turn off)
I do not understand anything about this and I prefer NOT to get into the technique, in such situations I call the master and he looks for a problem and fixes it himself. Here I am such a master scrapman that after me no one can fix a thing.
Maybe still try to repair myself?
So do I. Like most girls, I don’t dare to disassemble the laptop. Sometimes it turns on and off, but then I don’t dare to touch it for half an hour. It will stand and turn on normally. This happens most often in the summer, most likely due to overheating. since I have a bad habit of dragging it into bed with me, although if necessary, you can very carefully disassemble it and just as neatly put it back together, just so that there are NO extra parts left)

What do you think, what could be the problem gentlemen?
The laptop was spilled (by the client), he says tea, and it trudges with beer, I cleaned everything with alcohol and dest. With water. Because of the spilled chip, the start button was first stupid, the chip was cleaned, there are no more problems with it. Each time I went through a hairdryer and gave it a stand to dry completely.
Now he stood for some time and does NOT react at all. However, I pull out the plug for the (power) button and plug it back in, then connect the battery or power supply. (Or both), as it turns on immediately, then turns off after 1-2 seconds. Despite the fact that the working capacity of his norms, he checked before, everything worked. I think the problem is with the chip. After all, everything works, as if some stage of loading goes off and off. Anyone can give normal advice? Only “hands are not from there”, “pull out everything in turn and check” keep it with you.
Vitaly, you did everything right, but it’s better Contact a service center to a specialist. Most likely you have a problem with your motherboard.
I followed the instructions and it worked! thanks!
I also had a laptop working, but there were no pictures, I pulled it out and there was no operational sense. Then I pulled out the hard drive, cleaned the contacts on it and it all worked.
Problem: Aser Aspire E17 laptop, when turned on, Aser appears on the screen and the dots move in a circle, as when loading, but after 5-10 seconds some kind of click and the laptop turns off. If faced with a similar. Please comment and advise what it can be?
Help when turning on Asus appears on the screen and the dots move in a circle, as if booting, and so until you turn it off.?
The same, only with ASUS. I can’t help ((
I have such a problem. I turned off the laptop, after 10 minutes I pressed the power button of the laptop, it started working, after 5 seconds it turned on by itself. What are you, please help.
Such is the case just happened. I am writing from a tablet. I worked in a computer, it was on the coolers (stand) turned off, went to another room, pressed ON, the beech turned on and after a minute passed out. I pressed ON again, turned on again and turned off after 15 seconds. And again, and again. Here I sit, waiting for 10 minutes already. I’m afraid to press ON. Vague doubts plague me.
I have an HP g62 laptop, the same problem, only I was in social networks, and before that the laptop did not turn on, it was jammed with a drink, I wanted to listen to audio recordings in social networks. I turn it on, and after that 2-3 seconds it works, and turns off
So you have overheating gentlemen, clean it from dust and change the thermal paste once a year at least.
Here I have such a problem, the laptop began to show that there were some problems, and it began to reboot itself, I already had such problems, but I did the last time Restoration of the original version and all the rules worked, now the same system has happened, the current now I can not make a reset, now it turns on at all, the picture shows and turns off what could be the reason?
Interesting tips, but another question may be that the video card burned out
Aser laptop. The problem is that the power button (when you turn on the laptop) after turning on constantly turns off, then turns on again, and so on endlessly.
Where to dig.
My laptop turned on for 2 seconds and then turned off. I just removed the heat sink system, took off the percentage and fixed it normally. After that I turned on. When I screwed on the heat sink, I simply tightened the bolts unevenly. This may also be a prerequisite.
Good day, everyone, I have a problem with the compaq 7400 laptop, so I plug the power cord into the plug and it turns on for 1 or 2 seconds and turns off and so I am not special myself but repairs I do it myself, which is a desktop one that has laptops but everything worked for a laptop before started reinstalling Windows, the screen started Margo and went out and it turns on itself without pressing the power button and for 1 or 2 seconds the laptop is cut down all dismantled checked the cables disconnected the laptop manitor took off the screw We plug in the plug and it turns on and it turns on immediately DON’T touch the percent
if you have any ideas tell me pliz
After cleaning the cooler and replacing the thermal paste, the HP620 laptop turns on, the cooler works for seven seconds and the laptop turns off without even booting. Tell me what could have happened. D
Did you break or repair something while cleaning and changing the thermal paste? Recheck.
Pay attention to the flashing keys on the laptop (on / off, Kapsloka).
Thank you for the article. It helped a lot. Just the same problem, but not because of the display. The webcam is to blame
Why carry to the workshop, if you can yourself below
Thanks bro your article really helped. Before that, I was taking apart the laptop to the screw to no avail. Here I disassembled the monitor, fixed the loop everything in 10 minutes and everything worked. Thanks again for the article.
Sadly bro but again after starting 5 seconds and off. Spins the cooler. Works HDD and DVD. The screen is dark. This carousel started after I changed the battery
The indicator on the laptop is red, indicating a charge, but not charging. I turn on downloads to the desktop, the indicator shines white, supposedly fully charged, but in fact it shows less than half. The click, then turned on, works for a minute and is cut off, the indicator turns red again. I try to turn it on next, it starts loading for a few seconds. Click and chopped off. I turn on a little, everything starts anew, to the desktop and so on. Why am I sure that it does NOT charge. Although Asya will stay for the night while charging, the indicator is still red. And the attraction turns white. There is a nuance, the charging input somehow shorted out, the plug melted slightly, the input itself is externally NOT damaged, if at the time of loading or when the laptop is turned on, the plug is fully inserted into the click and cut down. What could be?
If the problem occurs after assembling or cleaning the computer, replacing the motherboard
If the problem with shutting down the computer immediately after turning on appeared on a newly assembled PC or after you changed components, while turning on the POST screen is NOT displayed (i.e., the screen does NOT display the BIOS logo or any other data ), then first of all make sure that you have connected the processor power.
Power from the power supply to the motherboard usually goes through two loops: one is “wide”, the other is narrow, 4 or 8-pin (can be labeled as ATX_12V). And it is the latter that provides power to the processor.
Without its connection, the behavior is possible when the computer turns off immediately after turning on, while the monitor screen remains black. In this case, in the case of 8-pin connectors, two 4-pin connectors can be connected to it from the power supply (which are “assembled” into one 8-pin connector).
Another possible option is to close the motherboard and case. It may arise for various reasons, but first, make sure that the motherboard is attached to the case using mounting racks and that they are attached exactly to the motherboard mounting holes (with metallized contacts for grounding the board).
In the event that before the problem appeared, you cleaned the computer from dust, changed the thermal paste or the cooler, while the monitor shows something when you turn it on for the first time (another symptom. after the first turn on the computer does NOT turn off for longer than the next), then with a high probability you did something wrong: it looks like a sharp overheating.
This can be caused by an air gap between the heatsink and the processor cover, a thick layer of thermal paste (and sometimes you have to see a situation at all when there is a factory polyethylene or paper sticker on the heatsink and it is placed on the processor along with it).
Note: some thermal pastes conduct electricity and, if applied incorrectly, may short-circuit the contacts on the processor, in this case, problems with turning on the computer may also appear. See How to Apply Thermal Paste.
Additional points to check (assuming they apply in your particular case):
- Is the video card installed well (sometimes it takes effort), is additional power connected to it (if necessary).
- Have you checked the inclusion with one stick of RAM in the first slot? Is the RAM inserted well.
- Was the processor installed correctly, were the legs on it bent??
- Is the CPU cooler connected to power.
- Is the front panel of the system unit connected correctly?
- Does your motherboard and BIOS revision support the installed processor (if the CPU or motherboard was changed).
- If you installed new SATA devices (disks, drives), check if the problem persists if you disable them.
The computer turns on and off immediately
One of the most common problems with a computer is that it turns on and off immediately (after a second or two). Usually it looks like this: pressing the power button, the power-on process begins, all the fans start up, and after a short period of time the computer turns off completely (and often the second press of the power button does NOT turn on the computer at all). There are other options: for example, the computer turns off immediately after turning on, but when turned on again, everything works fine.
This guide details the most common causes of this behavior and how to fix the problem with turning on the PC. It can also be helpful: What to do if your computer won’t turn on.
Note: before proceeding, pay attention to whether your on-off button on the system unit is sticking. this, too (and the case is NOT rare) can cause the problem in question. Also, if you see the message USB device over current status detected when you turn on the computer, a separate solution for this situation is here: How to fix USB device over current status detected System will shut down after 15 seconds.
The computer began to turn off when turned on without any action inside the case (before that it worked fine)
If any work related to opening the case and disconnecting or connecting the equipment was not carried out, the problem may be caused by the following points:
- If the computer is old enough. dust (and short circuits), problems with contacts.
- Failing power supply (one of the signs that this is the case. previously the computer was turned on NOT from the first, but from the second or third, etc. Times, the absence of BIOS signals in problems, if present, see the computer beeps when inclusion).
- Problems with RAM, contacts on it.
- BIOS problems (especially if updated), try resetting motherboard BIOS.
- Less often. problems with the motherboard itself or with the video card (in the latter case, I recommend, if you have an integrated video chip, remove the discrete video card and connect the monitor to the built-in output).
Details on these points. in the instructions What to do if the computer does not turn on.
Additionally, you can try this option: Turn off all equipment except the processor and cooler (i.e., take out the RAM, discrete video card, Turn off the disks) and try to turn on the computer: if it turns on and does NOT turn off (but, for example, beeps. in this If this is normal), then you can then install the components one at a time (each time de-energizing the computer before that) in order to find out which of them fails.
However, in the case of a problematic power supply, the above approach may NOT work and the best way, if possible, is to try turning on the computer with a different, guaranteed working power supply.
In another situation. if the computer turns on and off immediately after the previous shutdown of Windows 10 or 8 (8.1), and restarting works without problems, you can try disabling Windows fast startup, and if it works, then take care of installing all the original drivers from the site motherboard manufacturer.
Consider a situation where the computer turns on for a few seconds and then immediately turns off. What needs to be done and where to look for the cause of the breakdown.
The crux of the problem: Pressing the power button turns on the computer. Works from a few seconds (1-5 seconds) and turns off spontaneously. Sometimes the cooler starts to make noise. It is possible that the cooler turns only a few times and freezes.
To restart, you need to press the power button again.
How to find and fix the problem?
If there is a power problem, the result is:
- Lack of response to the power button of the computer (power supply). Power supply short circuit or hardware failure.
- The cooler on the power supply unit can make several rotations. Short circuit or failure of power supply or motherboard.
- The cooler on the central processor can start spinning and turn off after a second or two. Short circuit, failure on the motherboard or other module.
Common breakdowns in which the computer turns off immediately after turning on.
Shutting down your computer is just a consequence. The source of the problems could be:
- In the power supply itself. Dusty. Swollen capacitors. Destroyed transistors. Disassemble. check. replace.
- In violation of the contact of connectors and plugs of a laptop, computer. Oxides on the wires, loose plugs, poor soldering. all this can provoke switching on for a few seconds, activation of protection and shutdown. This process is cyclical, i.e. If you de-energize the device and then turn it on again, the same thing happens. turn on, 3 seconds, protect, turn off.
- In powered devices and modules. computer motherboard, laptop power circuit, etc. Assess visually. especially the central processor strapping. Carry out diagnostics. Ring the chains.
Why can the computer shut down during the first seconds? What happens during the start of the system unit?
I must say that it is the power supply that turns off the computer in case of any short circuit or excessive load.
Through the presence of a feedback system, it monitors the voltage in all circuits of the stationary computer, reacts to an increasing load, the presence of a short circuit.
All devices with a modern ATX switching power supply have this function. it works in the same way:
- The power supply turns on when you press the power button of the computer and undergoes a self-test.
- The power supply supplies 5 volts to the motherboard.
- Receives PG signal (Power Good).
- Continues to work.
If it fails at any stage. The computer will NOT start.
Causes of a short circuit in a stationary computer?
The most common prerequisites for a short circuit are:
- Incorrect installation of computer modules. For example: bought a memory bar or processor and inserted it incorrectly. the computer will start for a couple of seconds and turn off.
- In the computer, somewhere the contact to the connector is broken, the polarity of the connection is broken, or the insulation in the wiring is destroyed. This happens if the user often connects and disconnects the hard disk, power supply, plays with coolers.
- Cleaning a laptop or computer in violation of the rules. Conductive thermal grease has spilled onto the processor socket or pad and the PC will NOT start.
- Failure of the computer motherboard with poor cooling and violation of operating rules. In this case, most often the strapping of the central processor fails, which leads to a short circuit on the motherboard.
- Inadequate power and / or poor quality power supply. Such a power supply quickly fails under constant overload. The computer can turn on, but not the first time, suspended during games and watching videos.
May also shut down periodically under load.
For a better understanding of the problem associated with the spontaneous shutdown of a computer within a few seconds after turning it on, it is necessary to present how modern stationary computers function.
How to distinguish the indicated causes of failure?
- If the computer runs and shuts down for 1-3 seconds, the screen shows signs of starting the system. There is a power problem (short circuit).
- If the computer runs for five or more seconds and turns off, you can see signs of system start (UEFI screen, BIOS). Conclusion is a problem with the CPU cooling system.
Why is my computer shutting down? The reasons
- Short circuit (SC) in the power circuit (not necessarily in the power supply).
- Overheating of the central processor due to a malfunction of the cooling system.
- Overheating of the power supply. Most often due to failure of the power supply cooler.
In what computer modules do such failures occur more often? Where to directly look for the problem?
- Most often, the PWM power supply of the central processor in stationary computers fails. It is located on the motherboard near the CPU cooler. Look for where the 4-6-8 pin 12v connector is connected. The circuit serves to power the central processor, improving the quality characteristics of the input voltage.
Breakdowns can sometimes be identified by swollen capacitors and burnt-out mosfets on the board.
- In second place are problems with the video card. The additional power supply circuit of a powerful video card often fails, a failure leads to a short circuit. The location of the failure is indicated in the figure with number 3.
- Circuits on the motherboard. power supply for the chipset, RAM.
Here, as a rule, mosfets burn out, or electrolytic capacitors “swell” from overheating, greatly lose their capacity or “shorten”.
- Corrupted USB ports with mechanical damage can also be a prerequisite for shutting down the computer.
- Any other device connected to the power supply can be the source of the problem: hard drive, DVD, PCI devices, coolers and sensors.
Diagnostics of a PC, laptop, when the device turns on and off immediately, or after a couple of seconds, consists in identifying the faulty component and replacing it, or repairing the module.
It is better to carry out free diagnostics of a laptop or computer in a service center, or call a computer repair technician at home for 100% diagnosis and elimination of the cause. After all, time is the most valuable resource, and it can be quite difficult to diagnose the cause of a computer turned off quickly.
Another reason that the laptop turns off unexpectedly is the breakdown of the motherboard (oregano). This is the main component on which the rest of the components are installed (video card, RAM, processor), so even microcracks can lead to unexpected consequences.
Typical breakdowns of oregano:
- Mechanical impact (accidentally dropped the laptop, hit with a heavy object, etc.);
- Filling with water, tea, coffee;
- Incorrect actions (disassembly and incorrect assembly).
There may also be problems with USB ports, cooling system (overheating of bridges), video adapter.
Why the laptop turns off by itself: 9 reasons
Does your laptop shut down by itself? This is an alarm bell, which suggests that there are some problems with the laptop. Indeed, in most cases, the laptop turns off on its own due to the activation of the overheating protection. This prevents the possibility of damage to the device or its components.
Although there are other reasons why the laptop itself turns off. Therefore, below are the most common problems, as well as ways to solve them.
- Overheating of the laptop
- Dust clogging
- Laptop suddenly shuts down while running on battery
- Infection with viruses
- Motherboard malfunction
- The laptop often turns off by itself: other reasons
Overheating of the laptop
One of the classic reasons. The laptop shuts down by itself as it gets hot quickly due to its compact size. Especially if you load it with games or heavy programs. And even more so if you use a laptop on a sofa, bed or sitting in an armchair.
The fact is that it has special holes through which air circulates. This is how the laptop is cooled. And if you put it on a blanket or a thick tablecloth, then the holes are blocked, and air circulation is disturbed. The cooling system is NOT doing its job, so at critical moments the laptop spontaneously turns off. As mentioned above, this triggers the overheating protection.
Typical signs that your laptop is overheating:
- Does not turn on immediately after shutdown (it takes time for the components to cool down. then it will start)
- Automatically turns off under heavy load. during a game, encoding files or when running several programs at the same time (the more load on the processor, the faster it heats up)
- Too hot case (you can feel it by the buttons on the keyboard. it will be impossible to touch them).
But this only works if the overheating was due to a violation of air circulation. If the reason is different (dust, thermal paste), then the solution will be different.
Infection with viruses
Another reason why the laptop turns off by itself is viruses. There are a lot of them today, but this list includes such an infection as miners. They are used for Mining (earning) bitcoins. the now popular virtual currency. This is a rather insidious virus, which loads the processor and video card by 100%. It is so necessary that property (earn) bitcoins.
Therefore, if the laptop constantly turns off by itself, it makes sense to check it for viruses. To do this, install any antivirus (Kaspersky, Avast, Avira), and at the same time scan the Windows system with a special utility to remove malware.
Another reason why the laptop turns itself off during operation is dust. This is perhaps the most common problem. And the most common. users rarely clean their laptops, as a result of which they are constantly dusty. If the laptop began to turn off by itself. in 90% of cases, the reason is in the dust.
By the way, this problem is very closely related to the previous one. After all, dust accumulates everywhere: on the processor, video card and in the cooling system. And if you use the laptop on a fluffy blanket, then it will clog up even faster.
As a result, the cooling system is NOT doing its job:
- Air circulation is disturbed (in advanced cases, the dust layer is 5-10 mm);
- The fan hums loudly;
- The laptop starts to overheat, slows down, freezes.
And after a while, the laptop turns off by itself. And this again triggers the overheating protection.
These two reasons are the most common. If you clean the laptop from dust and make sure that the temperature is normal, then in most cases the problem will be solved. But there are others.
Laptop suddenly shuts down while running on battery
If the laptop turns off by itself without overheating, then the first thing to check is the battery status. To do this, connect your laptop to the network and work with it for a couple of hours. If it does NOT turn off anymore, then the problem is in the battery.
The fact is that the batteries usually last for 2-3 years. While laptops last 5-7 years. It’s a common thing: batteries always fail quickly.
Typical signs of their malfunction are:
- Incorrect determination of the charge level;
- Instantaneous shutdown of the laptop when pulling out the power cord (here the battery is already completely inoperative)
- “Absence” of the battery (the laptop can not determine it, I think that there is a battery at all).
The laptop often turns off by itself: other reasons
If the laptop shuts down by itself, and the temperature is normal, then the reason sometimes lies in the drivers. Because of them, there are many problems, including spontaneous shutdown of the device. You will NOT be able to check them manually, so here it is better to use a special program that will determine the relevance and performance of the drivers. And, if necessary, will offer to update them.
Another reason why the laptop turns off by itself is the BIOS. Errors in firmware can lead to device shutdown. If you have installed a new firmware and it is unstable, it is recommended to Roll it back to the old one. In some cases, resetting BIOS settings helps.
There are two more reasons why the laptop shuts down on its own. They are quite rare, but they do happen sometimes. The first is a problem with the power supply. Due to constant voltage fluctuations, the laptop often turns itself off. And the second one is problems with RAM. Here it is easiest to change it (after all, it is inexpensive), although you can give your laptop for diagnostics. perhaps it will be repaired.
For us people of the age, all this is not clear.
For you, people of age, it should be clear how to spell “not clear”.
When then you and you will be of age and you will also have young people to insert “hairpins”)))
Once a hyphen)) in your opinion to indicate errors to insert a hairpin? Young people are NOT capable of this, for they are illiterate)
Do not speak for everyone. Not all young people are illiterate. This is verified information.
Using “for” doesn’t make you smarter. There should be a dash between “indicate mistakes” and “insert a hairpin”.
Correctly. “Older people” are usually readable people. And punctuation is sacred.
9 reasons, and the text stipulates 6, yes cool
In “other reasons” there are 3 more.
Not one solution has helped.
My laptop turns off by itself NOT out of what just
HE SIMPLY BY ITSELF SOFTLY turns off. I have already tried to go through Aida and see
Go to the settings, system-power and sleep mode, suddenly you just have the time indicated there before shutdown, so it goes into sleep mode.
At least one good advice! Thanks)
How to understand “smoothly”? And it’s generally not clear whether the laptop overheats at the same time? Mains or battery operated?
And where is also a common reason, hub ?? Bridge blade.
A record comes out: there is a problem on your PC, you need to reboot. This record may appear 3-4 times in a row
thanks for the consultation
And if there is a lock, the laptop can be absent by itself, if it did not even have time to turn on
A question for those who are “in the subject”: Note (Toshiba, 6 years old, Windows7) always works on a stand with a fan. It works properly from the network and for as long as you like. After replacing the native battery with a new one (both China), it began to turn off periodically. over, at any charge level, even at 100%. Anyone have any good thoughts on this situation?
Most likely the board in the battery is running out. Is there an original AKB ?? If there is, take it and the Chinese one, take it to any workshop and ask them to replace the cans from the Chinese but the original.
I had a similar experience. Contacts are oxidized. I tried to fit it a little, cleaned it with zero sandpaper, washed it with alcohol. After sharply clicks the battery. You can try to fit the contacts with a fiberglass strip. Good luck to all !
You can try to remove it from the battery compartment and turn it on without it. If the laptop turns off, it will not mean the battery does not fit according to the version (revision).
I have such a thing, but I want to move the laptop to another table or move it, the HP PAVILION G6 laptop turns off immediately, about 5-6 years old, I don’t know what to do if anyone knows, tell me
Most likely the charging socket is loosened, and the battery does NOT hold a charge. So it turns off.
The laptop turns off after 10 minutes if I do not touch the mouse and reboots again it is NOT possible to watch movies. Tell me what is the reason?
In the additional power parameters, go to the settings for the transition to sleep mode and increase the transition time to sleep mode
It turns off for me. But the sound goes on. Does NOT respond to commands. We turn it off forcibly, after a while I turn it on. In the browser, tabs begin to fall, and then the browser itself. After twenty minutes the laptop turns off again. And so it is constantly. What is the problem? Prompt.
Guys such a thing, they gave away the trash for nothing, a laptop with all the components (operative, hard, battery, etc.) immediately after turning on it instantly turns off, that is, tying the power button for 2 seconds. Disables immediately, what could be the reasons?
Either the battery is dead, or the laptop is gone
Hello! Lenovo laptop, there was a problem with Windows loading and the laptop turned off after heating! We reinstalled Windu (it was cold), then it Disconnected! I read the articles, cleaned them neatly from dust, but the problem did not go away (the longer it washes, the longer it works, and then it turns off again!?
Thank you for the article! 🙂 As a beginner, advice helped me! 🙂
Laptop asus x54hr, he’s 7-8 years old, I’ve been working for 3-4 years already / playing with it without a battery (sat down), that’s probably about an hour, maybe an hour and a half ago, it began to turn off when I go into the game (the old one is relatively. ). The most interesting thing, yes, I suspected that it was from overheating, but why does it turn off once, no more. THOSE. Turned off, I turned on and I can work / play as much as I want, turned off Will not. Just yesterday it turned off and for the first time did NOT want to start right away, I had to wait. Turned on and again after 2 minutes passed out, but today I have NOT checked.
1. I clean it regularly
2. Windu put from the original image, clean, not assembly curves
3. I changed the thermal paste not long ago, for a new one, and not lying for years
4. Operational new, the CD fits perfectly, the firm is also good
5. Cooler for cooling is also new. Recently bought
6. I replaced the bios tablet about a year ago, there were no complaints
7. Firewood is all checked, off site.
What could be the problem?
Antivirus is not worth it, I periodically install and check the laptop, then delete it. The only moment he did not fall for a long time, and one of the cases you wrote was damage to the mother, but from mine it is described, what can you assume? Why is this happening?
There can be many reasons. I had the same thing (and also without a battery). The problem was solved when, after disconnecting, I completely disconnected it from the network and gave it a minute to rest. As in any other device (one of the most popular is a router), there is memory that is completely erased from a lack of power, and at the next boot, it prompts you to turn on in normal or safe mode. And then he himself will take and boot without pretensions.
Guys, can anyone help someone from HP’s laptop and is cut down after replacing thermal paste in games, put thermoplates. There was a case already and not with one such laptop, I tried all the thermal pastes and nothing helped, put the thermoplates and everything became fire
I bought a laptop from my hands in a workshop without a battery, it took about two weeks. And away we go. As soon as you turn it on, I took it back where I took it. They said the energy drops are visible, I don’t know what to do?
Hello, I turn on the laptop after 5 minutes by itself it turns off abruptly, then again this situation after turning on, the charger is connected, and does not heat up. What could be? thanks in advance.
Here’s the deal. I played the game many times, but the laptop did not disconnect. But suddenly he suddenly disconnected (this happens a second time). In the first case, I simply unscrewed all the bolts and put the battery back in 10 minutes. And in the second case, it often turns off when I start a game or watch a movie in full screen mode. I’m afraid to tell my parents. On the internet, I was told to update the driver, but when I update it turns off, the cooling for the laptop does not work, the wire comes off, but it works fine with cooling. And then a day later the cooler was no longer working because the wire came off. And if I write to VK on the browser, it will pour out after 20 minutes. I check for viruses constantly. They are not there. And this is the most important thing. I have 3 sisters. So when my younger sister watched cartoons, and my parents were not told that it was broken, it worked fine. This is strange. And yesterday when it turned off for me, I tried to turn it back on instead of the letters HP, I saw a white screen and abruptly pulled out the battery. And I know that a white laptop screen means that there is either no processor, or it has burnt out, or drowned. And the games are kept for 2 minutes, after that it turns off abruptly. The motherboard is ok. Tell me WHAT I DO?

Hello! All the same problems that everyone writes. The laptop works on the integrated video, when you start games (the same Tanks) for 20-40 minutes (the discrete video card turns on), the laptop turns off. that is, it turns off with additional load! [Notebooks only]. Don’t look at the power of the laptop. A lot of different equipment in a laptop, even more so! Normal operation of the equipment in combination with native or really suitable drivers is ensured by optimal sufficient voltage. This voltage should be given by the power supply unit that was included in the kit. If one is dead, you must NOT be toad and go buy ONLY the original one for your model. If you do not find and there is only Chinese shit, take with a higher output current! If THIS does not help, write a complaint to your power supply company, you have inappropriate voltage in your networks (by the way, you cannot see this by the light of the light bulb). Good luck to everyone and constant work.
The laptop turns off, a blue screen appears with a sad smiley and an error. In BIOS, I updated the settings, installed a new Windows, turns off and gives the same error. Help me please.
What if it usually turns off when turned on? Type is loading and suddenly turned off.
Guys, please tell me. (Acer laptop, Windows 8). It worked normally before, but then it became dull (suspension and buggy). And then when I played with my brother, the game froze. I accidentally unfortunately, several times on the switch button and closed the computer. Then we opened it, but it didn’t turn on. (The background was a dark light color). So it stood day and night. The next day, dad did something there and the laptop turned on. But then NOT how many times he turned off and we repeated, the same action as dad. Today is the third day. (12.28) He managed to turn off once. Help me please. Give advice.
The laptop turned off by itself, randomly NOT a suspension of what you do on it (you play or just sit in the browser) there was no overheating, after reinstallation it stopped turning off, but all programs started lagging, if before it was 100-120 fps now barely 5- 10, while the laptop itself is working fine, I tried to reinstall the drivers, nothing helped
Check your hard drive for errors
There is another possible reason (although this can be attributed to PSU). Lack of food. As in any other device, parts (conductors, resistors, transistors, etc.) start to fade over time. Or many devices are connected to the outlet at once, which in principle also refers to a surge in voltage, which is also very bad for the board, especially for the HDD. Too many devices and other equipment are connected to the laptop itself. It starts to slow down, then. to warm up, and. In other words, almost all of these reasons are interrelated and lead, in the end, to the same problem. shutdown. I myself, as an engineer working with electronics and computers, constantly face this problem. As at work (some kind of device works, it receives data via cable. But as soon as you turn on the data transfer via wireless connection, it immediately reboots. And if you connect this device to a cable with additional power supply (be careful with this, you can burn the device). so everything starts working right away.), and once at home I ran into it (I installed an HDD in a laptop instead of a cd drive. The main files I work with are on it, and accordingly. Consumption is greater, and one fine, and how usually a very NOT the right moment, it is cut out.). This I have NOT tested the power consumption of both. It is necessary to disassemble the Note.
Laptop shuts down due to hardware failure
It is very difficult to assemble all the necessary components in a laptop case, while the cooling system is ideally thought out. That is why, quite often, various elements fail on laptops. Let’s consider the main ones, which can lead to a computer shutdown when trying to boot it.
Damage to a HDD or SSD can occur for various reasons, such as physical damage from a shock. Another common prerequisite for a hard drive failure is an abrupt shutdown of the laptop, due to which the drive must make an emergency stop.
If the hard drive itself or the operating system files on it has been damaged, the laptop may shutdown in full boot. In such a situation, it is recommended to check the hard drive, installed it in another computer on which the operating system is loaded.
Defective power supply
Power supply failures can also be a prerequisite for shutting down the laptop immediately after turning it on. You need to check how the indicator on the laptop power supply works. It may work differently depending on the different versions of computers. Most often, the indicator should just light up green, and if, for example, it blinks, this indicates a malfunction and the need to replace the power supply cord or the unit itself.
A common prerequisite for why a laptop turns on and off immediately is CPU overheating. In most cases, it occurs due to the absence or drying of thermal paste. If this is the case, you will need to replace the thermal paste, which you can do yourself, if there are no difficulties with disassembling the laptop.
It is much worse when the central processor overheats NOT due to lack of thermal paste, but due to poor cooling, that is, improper operation of coolers and radiators. In this case, it is necessary to determine the cause of their malfunction and repair or replace. Problems can arise with replacing coolers in a laptop, since it is often difficult to find components on sale for NOT the most common models of laptop computers.
According to the recommendations of laptop manufacturers, every 6 months they must be sent to a service center for professional cleaning. This will allow the laptop to work as long as possible, and not having problems with overheating. If the coolers of a laptop are very dirty, then all components will overheat when turned on almost instantly: the central processor, graphics processor, hard drive, and so on. As a result, overheating protection will work, which will turn off the computer.
The easiest way to fix this problem is to disassemble the laptop and clean it correctly.
If the power supply or battery is unstable, a short circuit may occur in the laptop motherboard. Most often, it leads to burnout of capacitors on the computer motherboard, which is a serious problem. In such a situation, it will NOT work to repair a laptop on your own, and in a service center for such repairs you will have to pay a considerable amount.
Why does the laptop turn on and off immediately
While working with a stationary computer or laptop, the user may encounter both hardware and software problems. over, in the case of a laptop, such problems are much greater, since the device is much more complex than the system unit with a monitor. The most unpleasant and difficult situation is when an error occurs that does not allow the system to boot. One of such malfunctions that can be encountered is the computer shutdown before Windows starts or immediately after that. In this article, we will look at why the laptop turns on and off immediately, and what to do if such a problem occurs.
often than not, the laptop turns on and off immediately due to battery problems. Many users purchase laptops as desktop computers, install them at home and work with a permanently connected battery and power supply. This mode of operation is an emergency for the battery and will greatly shorten the battery life. If the battery has completely stopped holding a charge, the laptop may turn off immediately after turning on.
It should be noted that not only with severe wear of the battery, a similar problem may arise. It also takes place if, for example, the battery terminals have oxidized and the current and voltage of the required strength cannot pass through them.
Laptop shuts down on boot due to software issues
If the laptop turns off when turned on due to software faults, most often it is a BIOS problem. For example, malware can set the BIOS to automatically shutdown the computer after a certain amount of time. It is recommended to go into BIOS settings and reset them to default values to solve the problem.
If the laptop shuts down during boot due to problems with Windows, you can try to restore the integrity of the files or reinstall the operating system.
Reasons NOT to turn on the laptop
Consider the first group of reasons for not turning on the laptop:
- The power supply is faulty.
- The battery is completely discharged.
- Problems with the power connector: either it is broken or there is no contact. Also, a prerequisite may be a malfunction of the cord, plug, which are connected to an external power supply.
- Battery low. This is a commonplace reason the laptop turns on and off immediately. Therefore, device owners should monitor the battery level.
- The reason may lie in the BIOS of the motherboard. In this case, the firmware is either broken. Or it is completely absent. If the user violates the structure of the laptop, then the BIOS is locked.
- A short circuit has occurred in the power supply circuit. As a result. the binding of the Video chip or processor. The standby power microcircuit may even burn out.
- Malfunction of the central processor.
Also, if you press the power button of the laptop, the cooler can start working, while the indication lights come on, but the display does not turn on, which does not allow the operating system to boot. During this, the HDD activity indicators DO NOT flash.
If this happens, then you need to consider Possible reasons for this unpleasant situation:
- Lack of RAM or its malfunction.
- The lack of a central processor or when assembling the laptop, its fixation was broken.
- There is a north bridge on the motherboard, which is simply broken or soldered. This may be due to overheating of the laptop due to the fact that the cooling system is simply clogged with dust. This is why the laptop can turn on and off immediately.
- It often happens that the BIOS firmware fails, or rather the microcircuit located in it.
Instantly shutdown laptop. Identifying the causes
Turning off the laptop instantly prevents the operating system from booting. However, even with a malfunction of this nature, it is possible to provide access to the BIOS settings. Most often, the cause of this problem may be:
- Winchester is out of order. You need to check if the hard drive can be detected in the BIOS settings. If it is found in them, then look at the download process tab. This is necessary in order to understand from which device you can boot the operating system.
- The reason may be damage to SEPARATE segments of the hard disk. There is also a possibility that the OS bootloader has messed up. There is only one way to check the plausibility: the diagnostic program is started. It can be MHDD 4.6 or analogs of this program. If it is impossible to determine the hard drive in the BIOS, then this may indicate two reasons. a malfunction of the hard drive or the south bridge on the motherboard. To check, you need to connect a hard drive, which is capable of operating in normal mode instead of the tested one. If even in this case it is not possible to identify the hard drive in the BIOS, then you need to contact the specialists who will simply replace the south bridge.
- Failure of the operating system loader immediately manifest itself by the appearance of the message “ntldr is missing press CtrlAltDel to restart”. Instead, another can be written, but similar in meaning. The solution to this problem is very simple: you need to reinstall the system.
- The file structure of the hard drive may be damaged. In this case, there are attempts to load the operating system, but they are completely unsuccessful. The solution to the problem is reinstalling the OS.
What to do if your laptop turns on and off immediately?
Today we will look at:
Almost all laptop owners face problems of this nature: the device turns on and off immediately. To try to fix the problem that has arisen, you need to find out the reasons for its occurrence.
Tip: Before implementing the tips in this article, try scanning your computer for viruses using an antivirus. Very often the problem is solved this way.
Shutdown at the initialization stage. The reasons
A malfunction in the form of an instant shutdown of the laptop can also occur during the BIOS initialization stage. This is a fundamental difference from if the laptop was turned off when the operating system was loaded. In this case, either an instantaneous shutdown of the device occurs or a few seconds after it is turned on.
Let’s consider the most common causes of this phenomenon. Voltage does NOT come from the power supply. This may be due to the inoperative state of the cooler or dustiness of the cooling system. Also, the reason may lie in the incorrect assembly of the laptop cooling system. Because of this, the heatsink does NOT fit snugly against the crystal. Another instant shutdown of the laptop is a consequence of a short circuit in the south bridge or damaged BIOS firmware, a malfunction of the north bridge.
In general, the list of faults is quite extensive. It is quite difficult to identify the real cause, especially if it diagnoses itself. Even if it was possible to determine that the reason is in the electronic part of the laptop, then there is no need to rush to repair the device. Otherwise, irreparable damage can be caused.
Experts in this field will help determine the true reason why the laptop turns on and off immediately.
