The laptop does not turn on and does not show signs of life
In most cases, we have nutritional problems. The first thing to do is connect the laptop to the power supply and check that there is voltage in the outlet :). Power adapters usually have a light bulb to indicate that they are working. And on the laptop there is an indicator that signals the inclusion in the network and / or battery charge.
Most often, the power supply does not work, or it functions inferiorly (here just try a similar one), bad contacts in the connectors, broken or bent wires. Look at the whole thing and draw a conclusion. at what stage the power is lost.
To avoid problems with the power connector, I advise for the future to insert the power plug into the laptop first, and then only the power cord into the outlet. By doing this, we exclude the possibility of a short-term appearance of a spark when the plug is connected, which spoils the contacts.
If everything “burns”, and the laptop still does not turn on, then the problem may not be in the power supply. Try again to remove the battery and turn on the device again without it, then after 10 minutes put the battery back. Also, disconnect all connected external devices (you can also disable the Wi-Fi adapter if the design allows).
Try to turn on, and if it works, then return the devices one by one, and so you can determine what was the matter.
If your laptop does not turn on and there is still a warranty, then immediately contact the service center!
Perhaps this is all that you can do yourself without disassembling the laptop, if it does not show signs of life at all or shows a black screen. serious reasons may include a non-working motherboard, a broken internal power controller, a south / north bridge, broken contacts inside the device, BIOS firmware failure, and others.
Writes that it is impossible to start from the boot device
There may be different messages in English, for example “Error loading operating system” or something similar, and then the laptop will not boot. First, remove all flash drives and disk from the drive and reboot. If it does not help, then the matter is either in the hardware or in the software problem of the hard disk.
The first one is solved by contacting the service center, but first you need to check that the problem is in the disk. The most affordable way is to reinstall Windows yourself. If it helped, then the problem was at the software level.
Fans are making noise, but the laptop screen is not working
Maybe the laptop itself turns on, but the screen does not work. Take a closer look at the monitor, maybe there is something there, but the backlight does not work. Define the hotkeys for turning on the backlight on your laptop and press them. For example, on many Lenovo models, these are the “FnF2” buttons.
The screen may really not work, and there are also various artifacts instead of an image. The surest way to check if a screen or laptop is at fault is with an external monitor by connecting it to the VGA / HDMI output. If there is a picture on it, then the laptop screen will definitely not turn on. Read more about this in the article about stripes on the laptop screen.
A discrete graphics card can often be the cause of a malfunction, especially for those who like to play games on a laptop. Due to a poor cooling system, dustiness / pollution thereof, or improper use of your “friend”, video cards overheat and break down faster. This is especially true for nVidia video cards (GeForce 8400M, 8600M, 9300M and others).
No need to play with the computer on your knees, on your stomach, or in any position that blocks the vents. It is advisable to use laptop cooling pads. And in general, if a laptop is not positioned by the MANUFACTURER as clearly GAMING, then it is not recommended to play heavy toys on it for a long time, even if it pulls them. Monitor the temperature of your graphics card.
So, if the matter is in the video card, then try to pull it out, if the design allows, or turn it off using the switch that is present on some models. The beech can work without a discrete video card, demanding games just won’t run.
There may be more serious reasons: missing / not working processor or memory, broken BIOS firmware, non-working laptop north bridge (problems with the motherboard).
Laptop does not turn on. solution to the problem!
Worked your laptop for a year or two and stopped turning on? Or maybe he didn’t work at all Well, such a nuisance happens, and in this article I will tell you what you can do in this situation yourself, and when you need to contact the specialists at the service center.
All problems with a laptop can be divided into two parts: hardware and software. Hardware problems are physical problems with the device, i.e. when repair is needed “by hand”. And the software can be solved on the spot, without getting up from the chair. This includes problems with BIOS setup, operating system and programs.
First, let’s define our problem a little. If the laptop does not turn on at all, i.e. does not show signs of life, then the problem is definitely hardware. If it comes to loading Windows, but then something goes wrong, freezes, reboots, then here is 50/50. Next, I will describe the diagnostic steps, and you can skip those problems that you do not have. Accurate diagnosis of a malfunction is already half of the repair.
Constantly reboots or shuts down
The laptop can reboot indefinitely before attempting to boot Windows. This is a serious hardware problem, the south bridge may overheat, usually due to a short circuit in it. Most often this happens due to a breakdown via USB (remember what you inserted into the USB connectors).
Or processor overheating due to a dust-clogged cooler or a loose heatsink. But this is rare and is mainly accompanied by high fan speeds. In this case, the laptop may turn off or reboot at different times.
In the absence or poor power supply, the following picture may be observed: the device turns on, but quickly goes out due to a dead battery.
Turns on, shows a splash screen or writes something and hangs
It may be that the initial splash screen appears or information is displayed, but then the laptop does not start, it also beeps or writes about errors. The probable cause is problems with BIOS settings. You just need to enter BIOS and reset all settings to their defaults. In different versions, this item may be in different places, but the name is approximately the same “Load BIOS Defaults”. the keyword “defaults”. Then exit with saving the settings (“Save Settings and Exit”).
Please note that the system may be reporting some kind of error, but further loading is possible, you just need to press a button. For example, it can write “Press F1 to continue”, which means you need to press F1 to continue loading. This usually happens when the battery on the motherboard runs out (not to be confused with a large battery), the time and BIOS settings get lost. The battery must be replaced at a service center.
This is the simplest thing you can do yourself, because problems can be more serious, for example, a hard disk or RAM failure. With some skill, hard drive problems can be blindly diagnosed by listening to laptop When turned on, the working disk spins the engine and crackles for a couple of seconds, reading information. In case of problems, the engine may unsuccessfully try to start several times, or the heads crackle cyclically, trying to read something from the plates, while everything hangs on the screen.
Some models have open access to RAM sticks. If there is a suspicion of it, then you can try to remove the strips, carefully clean the contacts (see how to do this in the article “Why the computer does not turn on”). If it does not help, then leave one memory module (if there are several) and try to start. If there is only one bar, then move it to another slot.
Windows starts to load, but everything is bad
It’s a kind of option that, as usual, Windows starts loading, but then the laptop reboots itself, errors appear on a black or blue screen. Here again, there may be a problem in the hardware, ie. hardware failures, and maybe software.
The surest way to test, again, is to reinstall Windows. “Lite” check option. start from a bootable USB flash drive with Windows. If the laptop with it behaves similarly badly, then the case is probably rubbish, you need to carry it for repair. In general, the problem of loading Windows is a completely different story
Determining laptop malfunctions using the power and battery indicator
The Power and Battery Indicator indicates the operating status of the AC adapter (power supply) and laptop battery (battery). If, when you turn on the laptop or while it is running, you notice the blinking power and battery indicator, then this means that there is a problem with one of these two components: either the power adapter is faulty or the battery is having a problem.
Using the information below, you can try to identify the faulty component.
The laptop blinks and does not turn on!
How to identify a malfunction?
Is your laptop broken? Are you trying to turn it on, but there is only a blank black screen in front of you? This is a very unpleasant situation, but even in such a situation, you can try to restore its working capacity, or at least try to determine what exactly is faulty in the laptop.
Most often, the cause of the malfunction is one of the components of the laptop’s power system, but sometimes there are more serious malfunctions, which we will also consider in this article. We will begin to identify the faulty component a little later, since it is necessary to start with other steps.
You can find out possible causes and solutions to problems by going to the “Questions and Answers” section.
Central processing unit (CPU). it is the main working component of a computer. If the indication indicates to you a malfunction of the central processor, then you need to contact the service center for help. This problem cannot be solved on your own. Since the malfunction of the central processor may be the result of some other, more serious malfunction. For example, incorrect laptop power modes.
A rather rare malfunction. May occur when the laptop BIOS is not updated correctly.
Most modern laptops have BIOS protection and recovery mechanisms.
Therefore, if an error occurred in the functioning of the BIOS, you may not even pay attention to the indication, because if such an error is found, the laptop will restart and the recovery procedure will automatically start. When the recovery procedure is completed, the laptop will also restart. The only thing that you may notice is a longer (than usual) boot process, as well as a message on the screen that the BIOS has been recovered from an error. If this error occurs intermittently, you may need to update the BIOS.
If this type of error occurs, you can use the following guidelines to identify the faulty memory module:
- Determine how many slots and memory modules are installed in your laptop. The number of slots can be from 1 to 4
- Try to remove each memory module (if there are more than one) one by one from the slots and reinstall
- Try to install each memory module (if there are more than one) in slot 1 one at a time It is possible that only one of the memory modules is faulty
- Install another memory module with the same specifications and that is known to be good.
You need to contact the service center for help. In most modern laptops, the video card is integrated (soldered) onto the motherboard. Most often, this type of malfunction leads to the replacement of the laptop motherboard itself or the replacement of the video chip.
In this case, you also need to contact the service center for help.
To determine a malfunction in the laptop power system, use the recommendations described below.
Let’s start simple
The first check is best done with the outlet and extension cord. They can be easily verified using any other technique. Probably, it was the outlet that broke or the surge protector was simply turned off. The chance is small, but if so, the repair will be much easier and cheaper.
The second stage is the sources of power supply for the laptop. After inspecting the wires, you should make sure that they are not damaged (fractures, traces of pets, etc.). If you have basic skills in owning soldering irons, such breakdowns are eliminated quickly and reliably enough.
If the laptop still won’t turn on. There is another way to exclude (or confirm) breakdowns of the power supply unit. the use of a known good one. You also need to check the condition of the connector. To begin with, at least its visible part. it can be broken.
After that, disconnect the battery and try to start the laptop. The battery may not be working.
Why won’t my HP laptop turn on?
If your HP laptop stops turning on, let’s look at the algorithm of user actions in the most sad situation. the laptop does not react to the power button in any way. The first step is to look at the warranty card. If the service period has not yet expired, then it makes sense to contact our HP service center. In the best case, the breakdown will be eliminated free of charge, in the worst case, you can always refuse warranty service. The main thing is not to take independent actions before contacting the SC.
If the warranty has expired or the malfunction does not apply to warranty cases, then you can take a screwdriver and common sense in your hands and start diagnosing.
Laptop won’t turn on
- HP laptop upgrade from 1900 rubles.
- Replacing a video card from 1100 rubles.
- Repair and replacement of batteries from 240 rubles.
- Repair and replacement of motherboards from 450 rubles.
- Soldering and replacement of chips, video cards, processors from 1500 rubles.
- Repair of connectors and USB ports from 800 rubles.
- Repair, replacement of the keyboard on a laptop from 600 rubles.
The range of problems for which an HP laptop does not turn on is very wide. This could be due to overheating or damage to system board components, peripherals, and power problems. Sometimes one breakdown is combined or has a floating character.
However, there are several signs that will allow you to determine the direction of troubleshooting (or eliminate it), even without special skills. The first step is to carefully observe the reaction of the laptop to the power button.
- There is no reaction to the button as such. Most likely damaged power circuits.
- The indicators light up, the cooler of the cooling system starts up, but then it turns off. Problems during the initialization phase of the peripheral. most likely damaged connected devices.
- The start-up process is interrupted at the stage of loading the operating system. The OS was critically damaged, possibly along with hardware malfunctions.
If everything is in order with all the power supply elements, then you should check all those connected to the motherboard. To do this, you need to familiarize yourself with the procedure for disassembling your laptop model, and get down to business.
The computer should be disassembled, and everything that can be disconnected from the motherboard:
- random access memory;
- network card;
- optical drive;
- keyboard and touchpad;
Then plug in the power supply and very carefully plug in the devices one at a time while trying to start the system. The device, after which the HP laptop will stop turning on, is the root of the problem. With the received data, you can go to the service center or replace the problem unit yourself.
And if the motherboard won’t start even without all the peripheral devices, then some of its components have failed. Here professional diagnostics is already necessary.
So, your laptop won’t start. What to do? If you have been safely working at your “machine” for a long time, with all this, options with a lack of electricity, batteries and malfunction of any computer hardware are already excluded, then most likely the problems are caused by viruses.
Virus attacks, as you know, have taken place at all times of the existence of the PC. Hackers and other ill-wishers are ready to go to any lengths to obtain information and damage it. Thus, various “Trojans” are able to bring the computer to a state of “white heat” in which you will lose control over your operating system. In addition, viruses are capable of erasing information. Absolutely any. Personal files of different content are susceptible to attacks, but first of all, when the computer becomes “sick”, system files are affected. In this simple way, some important details of your “operating system” can easily be wiped off the face of the earth. As a matter of fact, after important files are deleted, then the first time you restart the system, you will encounter the fact that the laptop does not start. “Black Screen of Death”. this is the name of that picture when only a black screen opens before the user when the computer boots. In the best case, a cursor will appear that can be moved around the monitor.
What to do if your laptop does not start due to virus attacks? First you need to try to clean your computer from pests. This can be done using special antivirus programs. In addition, the Windows Recovery Tool can help you with this task. Asus laptop or any other does not start. does not matter. Viruses do not bypass any computer.
If you don’t want to once again figure out how to cure a computer system, you can simply update it. That is, reinstall. Format your hard drive and install a brand new OS. That being said, make sure you have a good antivirus program this time around. Also, be very careful when downloading certain files from the Internet. Don’t visit questionable sites.
If the laptop does not start, the black screen, signaling its “off”, still did not light up and boot, but the noise from your “iron friend” comes. this means that you simply do not have initialization. That is, the computer seems to be turning on, giving signs of life (namely, the “cooler” turns on and makes noise), the “caps” and “on” indicators light up. all. Nothing else. The fan is spinning wildly, the “PC” hangs and does not move from a dead center.
What could it be? There are several reasons for this. The first is perhaps the least enjoyable. lack of “iron”. To be more precise. processor or RAM. That is, of course, these “spare parts” are there, but they are in a faulty condition. A more favorable reason for your own correction. broken BIOS. In this case, you need to reinstall it and try to turn on the computer. By the way, if the laptop does not start, do not try to replace its constituent parts yourself. are more likely to be left without portable equipment completely.
Restart at boot time
If the laptop does not start. HP, Asus, Acer or any other (regardless of the manufacturer). when the operating system boots, or rather the OS is constantly rebooting even before you can contemplate your desktop or even the words “greetings”, then there are quite a few problems. Most common. these are viral attacks. But there may be some failures and malfunctions. If you are overtaken by this problem, then the simplest solution. reinstalling the operating system. Just put a clean “Windows” on a formatted hard drive and all startup problems will be resolved. Of course, if you are a fan of “digging into” the root of the crash, you can try starting in safe mode and look for what exactly is the matter in order to bypass the process of “demolishing Windows”.
Now let’s get closer to more “mundane” options for why the laptop does not start. Quite often, problems arise directly at the start of the operating system. For example, “Windows” does not start on a laptop at the very beginning of initialization. That is, at the stage of the appearance of a characteristic company icon. Why the laptop won’t start?
This kind of problem happens mainly due to the fact that the computer simply does not see the hard drive on which the operating system is installed. Thus, if you are sure that the problem is not in the processor or RAM, then check if everything is fine with your “hard” one. This action is done by studying the BIOS. If in the settings of the download queue, for example, you do not see the HDD, then the matter is in the hard disk. In this case, it must be replaced. It is not recommended to put your hand on the fragile and small laptop equipment on your own. Replacing the hard drive on a “laptop”. the procedure is delicate and rather complicated.
Doesn’t start to “music
It may also happen that the laptop does not start, but there are still reactions to manipulations. This is already a good sign. it’s not about tech, you don’t have to buy a completely new laptop. Usually a pretty encouraging sign. characteristic “beeping” during the first seconds of switching on.
What are they signaling? In general, there is a huge amount of literature, which clearly describes all the “beeps” and the reasons for their appearance in the absence of a full start of the computer. So if you turn on your portable equipment, and it “beeps” at you, there are two ways out: read the literature or take it to the service center. You can also contact your friends who have already had to deal with such a nuisance.
There is no reaction
So, let’s take a look at a rather rare, but very sad reason that the laptop does not start. You are trying to turn on your little “iron friend”, but he does not react to your actions at all. That is, an absolute vacuum. No noises, sounds of switching on, squeals, squeals, rustling and clinking. only silence.
If you asked yourself the question: “The laptop does not start, what should I do?”. and are faced with a complete lack of reaction of this technology to all your vain attempts to turn it on, then make sure that the laptop is in good working order. Of course, this will not be as easy as in the case of a stationary PC, but it is necessary to find out what is the cause of “death”. Take the laptop to a service center. there you will definitely be told whether your “laptop” is subject to resuscitation.
Is there food?
Another reason why the laptop does not start. this is the lack of battery power and, as a result, the lack of power supply to the equipment. So before going to the service center, first make sure that your outlets are in full working order. Thus, before you sound the alarm, try connecting your laptop to different outlets in the house.
Alternatively, insert the battery into your laptop and let it recharge for a while. The fact that power is supplied is usually signaled by a special indicator light. If it doesn’t burn. the battery is out of order. But the laptop can work without it, only from the network. So don’t panic right away.
Why does the laptop not start, what should I do? List of possible malfunctions
So, about 8 years ago, “laptops” actively burst into the world. They immediately began to be in active demand. Therefore, before discussing why the laptop does not start, let’s talk about the advantages of this technique.
Why the laptop won’t turn on and boot: all the ways to solve the problem
Hello everyone! Since you will find another portion of nonsense on this topic on the Internet, I decided to write my disassembly article to solve the problem when the laptop does not turn on, does not boot, or does not react at all to the user after it has been abruptly passed out. First of all, consider the symptoms:
- When you press the button, nothing happens, and the laptop stands dead.
- The laptop still turns on. you hear the sound of spinning fans, the lights on it light up, but neither the system nor the BIOS boots, and the screen still remains dark.
- You see the BIOS boot window, but the process does not go further.
- The operating system refuses to boot.
- When the system boots, the “blue screen of death” comes out.
- Hard disk boot error gets out.
Now let’s look at the reasons. why the laptop does not turn on or does not boot completely:
- Error in boot files or operating system drivers.
- Power problem
- Hard drive malfunction or breakdown.
- Oxidation of contacts or damage to RAM.
- Overheating processor.
- The south bridge of the motherboard is overheated.
- It worked fine, but it went out sharply due to problems with the crystal on the video card.
You need to understand that a laptop is still the same computer, but it has a more compact size and all the components are in a limited space. By the way, because of this, some problems may arise, which I wrote about above. Instructions and methods for elimination are suitable for all laptops of companies: Acer, HP, Lenovo, ASUS, etc.
Hard disk boot problem
At the same time, the laptop abruptly stopped loading the operating system, and on the screen you can see this message.
The problem occurs due to BIOS settings, where incorrect BOOT configurations are registered.
- When turning on or restarting the laptop while the BIOS is loading, you need to press one of the keys in order to enter the settings. The most commonly used keys are F2, Del, F10 or Esc (see the table above). You can also use the boot screen hint.
- Find the “BOOT” section in the BIOS and go there. Next, in the first position you need to install the “HDD” or “SSD” disk.
The problem is in the video card
If you have a separate monitor, then try connecting it. To do this, you can use: DVI, HDMI or VGA cable and connector. If you see an image on the monitor, then most likely the problem is in the video card or in the screen itself. for example, the loop has moved away or oxidized.
The image problem may be due to a banal shutdown. Some laptops have a special keyboard shortcut that turns off the screen when pressed. When the system is turned on, the screen can also be turned off. Locate the icon with the crossed-out screen on the keyboard in the row of “F” buttons. Press the “Fn” button and this very key.
If anyone knows, the image transmission to the second connected monitor can be carried out when the main screen is off. this is the usual mode that is found on almost all laptops.
But sometimes such a bug is triggered. when this mode is turned on when the laptop is not connected. In this case, the image is fed to the output port of the video card, and there is nothing on the screen. To enable this mode, find the icon on the top line: “laptop crossed with a screen”. Then press the “Fn” button and on this key.
There may also be a problem when you see some kind of “artifacts” on the screen: sticks, dashes, stripes, squares. At the same time, the BIOS is loaded, the Windows screen is loading, but after that a black screen and the system does not boot. Before that, the laptop turned off and does not turn on again. In this case, the shutdown can be during operation.
NOTE! In safe mode, the system boots quietly, but the screen still shows “artifacts”.
This is a completely home-solvable hardware problem and has to do with the chip on your graphics card. Soon I will write a separate article on solving this problem and leave a link here. While the article is under construction.
First, let’s check that the problem is with the video card, and not with the monitor. Turn on the monitor menu. if everything is displayed correctly, then go ahead. Another symptom is that the system does not want to boot beyond the Windows boot screen, and the screen goes blank.
Bottom line: blade of the GPU central die due to oxidation of contact balls. As I said, the problem is solved at home. I already wrote detailed instructions about this, and you can read it here.
What if the laptop does not turn on at all, or nothing is displayed on the screen? First of all, let’s check its nutrition. Take the power supply and plug it into a power outlet. We look at the laptop itself. the charge lamp should light up on it.
If this did not happen, then we look at the power supply, it also has a charging indicator. it should be on. If the light on the power supply does not light up, then this may indicate a malfunction. You can also try to connect it to another outlet. you never know, maybe it just out of order.
If both indicators are on, then hold the laptop like this for about half an hour to make sure that the battery will be charged at least to 30%. Sometimes it happens that the battery sits down almost to zero, and it takes time for it to charge to the level to turn on the laptop. If after a while the laptop still does not turn on, then try removing the battery. To do this, you will need to unscrew the back cover.
Then put the power supply back in and try turning it on. If it turns on, then there is a problem with the battery.
NOTE! It is advisable to turn off everything connected to the USB connectors of the device: mice, keyboards, hard drives, modems, etc. Also remove the disc from the CD / DVD drive, if there is one.
OS boot problem
If the system hangs at the moment of loading, then you can try to restore it. Also, the breakage could be caused by drivers or crooked updates.
When turning on the laptop, hold down the “F8” key and do not release it until you see this menu. Next, you need to select “Safe Mode”.
- Go to “Start”, then click “Control Panel”.
- Go to the “Recovery” section. If you do not see it, then set the “View” mode. as “Large icons”.
- Click “Start System Restore”. Then just follow the instructions. You also need to choose a restore point. it’s best to choose the earliest one. We are waiting for the procedure to end and the computer restarts.
Unfortunately, the top ten removed the ability to enter Safe Mode. Therefore, to restore, you need to do the following:
- You need to create a bootable USB flash drive or installation flash drive with your version of Windows 10. see the instructions here.
- We insert the USB flash drive and reboot or turn on the laptop. You need to call the usual “BOOT” menu. look at the third column.
- Before the first boot screen, click “Next”.
- Now you need to click “System Restore”.
- We have several options. You can just click “System Restore”. You can also try to do “Startup Repair”.
- It is also possible to launch Safe Mode via the command line. To do this, you need to enter one of the commands there:
- bcdedit / set safeboot minimal. enable safe mode
- bcdedit / set safeboot network. enable safe mode with network support
- bcdedit / deletevalue safeboot. disable safe mode
- After entering the command, close the command line, turn off the laptop. And turn it off again. After you get inside Safe Mode, click on “Start”, then enter the phrase “System Restore” in the search bar. At the very end, we just start the service.
Attempting to solve hardware problems
ATTENTION! All of the following instructions you do at your own peril and risk. Our portal is not responsible for your actions. Everything needs to be done with a clear understanding and some experience. If there is a friend with “straight arms”, then it is better to ask him. You can also watch a separate video below. But remember that we will not do simple cleaning and parsing, but minor repairs. so be sure to look at the steps that I wrote.
Now we will try to disassemble our laptop. First of all, we will clean it from dust, which is often the cause of breakdowns and non-switching on of the laptop. We will also try to solve some obvious problems at home. Try to do everything as carefully as possible.
- Disconnect the laptop from the power supply. Remove the back cover and remove the battery.
- Now one of the most dreary activities. you need to unscrew all visible and invisible bolts from the back cover. This needs to be done to remove the back cover to expose the inside of our computer. Try to put all the bolts in a prominent place.
How to Fix a HP That Will Not Turn On, Freezes Or Turning On Then Off
- Now we got to the most important reason, namely the oxidation of the contacts of the RAM. This reason is so ancient and occurs most often that we describe it first. Gently pull out all RAM dies.
- You need to take each plate and clean the contacts. For this we will use a regular eraser. We clean it like this. every memory stick on both sides.
NOTE! If you don’t have an elastic band on hand, you can use something metallic, like a paper clip. Just scrape the contacts lightly with it.
Next, insert all the dies back and connect the laptop to power. Try turning it on. If it turns on, then we just collect it back. If not, then we will try to check each plate separately (if there are several of them). insert each plate separately and try to turn on the PC. You need to try to identify the broken “RAM”.
If the process fails, try checking the hard drive connection. Just pull it out of the socket or unplug the power wiring. And then put everything back in.
We will also try to remove the keyboard and see if there is a “dust cushion” inside, which can greatly overheat the device.
- On the back of the motherboard, there should be a ribbon cable from the keyboard. Gently pull it out of the slot.
- You just have to pry the keyboard with something thin and remove it.
- Sometimes you need to additionally remove the top panel that goes next to the screen.
- When you remove and unplug the keyboard, make sure all the cables are connected to the motherboard. You can even unplug and plug them back in to remove the oxidized layer.
- Now you need to completely clean the insides of dust. Be sure to clean the dust from the internal cooling fan. If the “dust pillow” does not lend itself, then you can use a match or cotton swabs. You can even vacuum it.
- I would also completely remove the cooling system and clean the insides of dust. As you can see in the picture below, these “dust cushions” can accumulate and interfere with cooling. In this case, the laptop can turn off immediately even when it is turned on for the first time.
- And of course, do not forget to change the thermal paste on the processor.
- At the very end, you need to put everything back together, screw and connect all the cables, and only after that turn on and test the laptop.
NOTE! If none of the methods worked, then you need to carry the laptop to the service center.
Hard drive defective
Usually, when a hard disk fails, the start occurs, but the system simply hangs on the manufacturer’s logo or displays information that the disk is not a system one or is damaged.
If the hard drive is defined in SETUP, then you can independently perform its diagnostics by booting from removable media and running a specialized utility, for example, Victoria. In case of confirmation of the worst fears or the impossibility of identifying the device in the BIOS, you need to check the loop.
In extreme cases, you need to replace the hard drive yourself or with the help of our specialists, for this, click the “Request a call” button.
In fact, the malfunction may lie in a number of other problems. Among which are the following:
- damage to the processor or memory;
- broken BIOS firmware;
- Windows errors.
If the PC beeps when turned on, then this indicates in most cases overheating or problems with the RAM. If you have little experience, you can try to find out on your own why this is happening. To do this, it is necessary, first of all, to remove the dust. If the problem persists, you can replace the memory modules with known good ones.
Broken BIOS firmware may result from an incorrect update. If, before the problem occurred, the user tried to carry out this operation, then he will have to contact for repair.
BIOS configuration errors are also common. It is very easy to solve this problem on your own by simply going to the SETUP menu and loading the default settings, for example, by selecting the Load Setup Defaults option.
Errors in the work of Windows can lead to the fact that the OS does not start. First of all, you need to find out their cause and try to solve it. Alternatively, you can try reinstalling the operating system or restoring it from the factory.
The laptop does not turn on at all
Very often, the laptop will not turn on at all due to power problems. But if the computer does not turn on, what to do? The power button is lit after pressing and nothing further happens. We’ll have to look for the cause and eliminate it.
Typical actions that cause a laptop to stop turning on:
- dust cleaning;
If errors were made during the cleaning or updating process, then the behavior of the computer can be very different. Including the start may not occur at all. In addition, the system may not turn on due to problems with the hard disk and after overheating.
In some cases, the computer may turn on and even work normally for a while. Then a spontaneous shutdown occurs. There are several main reasons for this.
Let’s consider the typical problems that lead to the shutdown of the device without any indication from the user:
- malfunction of parts;
- software bugs.
Overheating is the most common reason for random shutdowns and reboots of mobile PCs, which can lead to device breakdown in the future. In order to avoid this, it is necessary to regularly remove dust, as well as sometimes change the heat-conducting paste.
How to Fix. HP Laptop Won’t Turn On / Freezes Or Shuts Off at Start Up / No Power Repair
Malfunction of parts very often also occurs due to overheating. If there were no regular cleanings, then the likelihood of this is high. You will not be able to solve such a problem on your own. Therefore, you should contact our specialist immediately.
Viruses can lead to incorrect operation of the system, as a result of which the PC can turn itself off. To solve it, you need to download special utilities from the Doctor Web site or Kaspersky Lab, perform a full scan and remove threats.
Software errors also often lead to an arbitrary shutdown of the laptop. You need to find the reason using the code that appears on the screen at the time of the failure. After that, the problematic application should be removed or try to update to the latest version.
Checking for battery problems is straightforward. You need to remove it, connect the charger and start the laptop. If the glitches are gone, then you need to replace the battery.
Problems may occur during the update. Failure to install updates correctly may cause the computer to stop turning on.
In this case, the user can install a new version of the BIOS, drivers or patches for the operating system.
The most difficult case is the inability to start the computer after updating the BIOS. This happens when the user tried to intervene in the process, for example, by restarting or shutting down the computer during it, or when using unofficial firmware.
Of course, it will not be superfluous to reset the settings to the standard ones. This can be done by removing the battery for a few minutes or by closing the corresponding jumper on the motherboard. But as practice shows, this probably will not help to fix the problem. The only way out is to contact the service center for repair.
In a situation where errors started after installing driver updates or Windows, you can simply roll back to a previous restore point from Safe Mode, reinstall the operating system, or return to the state it was at when you bought it, if this function is available in the model.
Defective hard drive
The hard drive stores all the information and the operating system of the computer. If it malfunctions, the computer can be turned on, but it freezes before the Windows splash screen appears. In some cases, an HDD error message may be displayed, for example, information that the disk is not a system one.
In any case, the user still has the opportunity to enter the BIOS SETUP menu. There you can check if the hard disk is detected and the correctness of the settings. If the hard drive is visible, then you can start the system from a boot disk or flash drive and test it.
Power problems very often cause the PC to stop starting. Although the problem seems serious, in most cases it is quite easy to diagnose and fix it at home.
Major power problems:
- incorrect adapter connection;
- damage to cables and connectors;
- battery malfunction;
- breakdown of the power supply;
- power supply problems.
Often, with such problems, the power indicator of the laptop does not light up. First of all, you should check that the power supply is connected correctly and that it is plugged into an outlet. It is worth noting that even very experienced users may forget to connect the PC to the network. As a result, after the battery is discharged, the device stops starting.
Damage to power cords and connectors can be caused by a variety of reasons, including rough handling or pets that chew on the cord. You can check this malfunction using an external inspection.
Another very common problem is related to the battery. In some cases, if it does not work, then the PC stops turning on even with the network adapter connected. Usually, after pressing the power button, even the cooler does not work. Therefore, it is worth trying to run a mobile computer on AC power without a battery.
The power supply fails quite often for any device. Without a charger, the laptop battery will run out sooner or later, after which the computer will stop turning on. It is very easy to check if the network adapter is working. It is enough to connect another charger from a known working computer.
Many power supplies are equipped with an indicator. Even if the light is on, it is impossible to completely eliminate problems with the network adapter. It is worth noting that there are many power supplies for laptops. Only adapters suitable for a particular model should be connected to a computer.
Power supply failure problems are much less common, but they are more serious. In this case, it will not be possible to independently diagnose and even more so fix the problem. You need to contact the specialists from our service center. Leave a request and you will be called back within a few minutes.
