The power indicator is on, the laptop does not turn on: causes and solutions
In some cases, it turns out that, despite the fact that the power indicator is on, the laptop does not turn on. Why does this situation arise? What do you need to pay special attention to? What may be required to correct this situation? It is actually not as easy to understand all the emerging issues as it might seem at first glance. The personal computer is a rather unpredictable piece of equipment. Power up problems can be the result of many failures. Some users are in a hurry to go to service centers. This is not recommended. First, it is advisable to independently diagnose the problem that has arisen. It may be possible to cope with the situation without outside help.
The laptop won’t turn on even though the power light is on? There are various reasons for this phenomenon. The first thing to think about is a problem with the card. In the case of a stationary PC, it is quite easy to detect and fix such a breakdown. To do this, just take out this component and connect it to another machine. But in the case of laptops, the user will have to try. If you suspect a malfunction or breakdown of the card, it is recommended to contact the service centers for help or call the system administrator for help. You don’t even have to try to diagnose the problem yourself. The laptop usually turns on by itself. you can hear the cooler. But there is no picture on the screen. Sometimes you can even hear the operating system loading.
If the power indicator is on, but the laptop does not turn on and the problem with the card is excluded, then the monitor may be damaged or broken in the device. This is an extremely rare occurrence that sometimes occurs in practice. If the display is broken, the reasons for the breakdown are likely to be the same as in the case of the card. In this case, there will be no image on the monitor, but the sound of turning on the OS will appear. You will NOT be able to deal with this problem on your own. Your only option is to buy a new laptop. You can try to contact the service center under SIMilar circumstances. Perhaps the display can be repaired there. Usually, after such a repair, the devices do not work for long. Ultimately, you still have to replace the laptop with a new one.
The following possible situation can be corrected without assistance. What if the power light is on but the laptop still won’t turn on? The main reasons for this phenomenon are a crash or reset. The BIOS settings may have gone wrong. It is for this reason that the problem in question may have occurred on the laptop. In this situation, it is recommended to perform a BIOS reset and the computer should then be fully operational.
Lack of ingredients
What else could have caused this problem? If we are talking about a new laptop, which worked before, this should not be ruled out the absence of any components. If the laptop itself turns on, but nothing is displayed on the screen, And the NumLock and CapsLock buttons do not go out, then the BIOS is probably being initialized. Probably, the laptop has RAM or a processor. If we are talking about a device that was previously functioning, then the reason may be hidden in the breakdowns of the components listed above.
In some cases, it happens that despite the power indicator is on, the laptop still does not turn on, although it worked normally before. The hard drive is causing the problem. One small crash is enough for the computer to refuse to start. In this case, the power button will still be lit. You may also notice that the fan is operating normally. In this case, the NumLock buttons and others light up and go out, as expected. It is recommended to disassemble the laptop and disconnect the hard drive. Now try switching on again in this state. It did not help? Then you can try again to gently attach the component. If the problem was a crash, then it should go away.
What if the power light is on but the laptop still won’t turn on? Diagnosing the problem in this case will require certain knowledge from the user. DO NOT rush to take your computer for repair. It should be borne in mind that most of these problems are usually solved with the help of a specialist. You can solve the situation yourself if the problem is with the battery. She was probably just discharged. Then it will be enough just to connect the power to the network and the computer and try to turn on the devices again. It is best to wait a few minutes before pressing the laptop power button. This will allow the battery to receive some charge. This technique turns out to be quite effective. Some experts also recommend removing the battery completely from the laptop and then connecting the power cord to it. After that, you need to turn on the computer and observe the situation. If the computer is working at full capacity, then nothing else needs to be done. Otherwise, the source of the problem will have to be addressed elsewhere. Practice shows that a discharged laptop or battery problems are quite common. These problems are eliminated quite easily and without assistance.
What to do if Samsung laptop won’t turn on? In this case, the power indicator is on and the cooler is working. The following reason is quite rare. It is almost impossible to diagnose it yourself. This malfunction can appear if the laptop is damaged in the south or north bridge. Why does this situation arise? Bridge problems can be caused by a variety of reasons, such as short circuits resulting from temperature differences. If, because of this, the USB port on the laptop is damaged, then the appearance of the problem under study will be quite likely. In this case, there will be only one method of fixing this problem. repairing damaged components. Buying a new PC will be the most effective way to solve this problem. Repaired components in laptops are unlikely to last long. Here, each user will have to independently decide what to do.
If the laptop refuses to turn on, but the device has previously functioned for some time, then you should think about the impact on the device of viruses. Often, a computer infection leads to the fact that the computer SIMply stops functioning normally. In some cases, it comes down to BIOS virus damage. In this case, problems with turning on the laptop may occur. It is unlikely that you can fix the problem yourself. As with most of the previously mentioned cases, it is best to take your computer to a service center right away. Here you will be helped to restore the laptop to work and cure it from viruses. Fortunately, this scenario is quite rare. However, it should be excluded, especially in cases where the user himself admits the presence of viruses on the computer. In some cases, problems associated with switching on the laptop occur after the OS is treated. In this case, it will be enough to first reinstall the BIOS, and then the operating system. After that, no problems should bother you.
Let’s summarize preliminary results. To begin with, it is worth noting that diagnostics and troubleshooting in most cases boils down to contacting a service center. Most often, many do just that. After all, a laptop is a rather complex device. It is actually not as easy to repair it yourself as a desktop computer. If you cannot figure out on your own why the computer does not turn on, then you can immediately contact a specialized service center for help. If you suspect a specific problem, be sure to inform the service center staff about it.
Starting a laptop without a power button
A broken power button on a laptop is a common problem for many users. This situation leads to the inability to start the device. It would be most correct to fix the button, but it is not always possible to do this manually or immediately take it to a service center for repair. You can start the device without this button, but this is done in two SIMple ways.
Almost all modern laptop computers are equipped with a special button that allows you to launch a special menu. Most often it is located somewhere on the side of the case or at the top near the display and is pressed with a finger or a needle. You can turn on the laptop using it as follows:
- Examine the case of the device carefully or look for the description in the manual to find the button you need.
Press it once and wait for the menu to launch. A small blue window should appear on the screen. Move around it using the arrow keys, select “Normal Startup” and press Enter.
After a while, the operating system will boot successfully. Of course, you can use this button all the time, but it is not always convenient and causes some difficulties. Therefore, it is better to set certain parameters through the BIOS. Read more about them below.
We start the laptop without the power button
We do not recommend disassembling the laptop and trying to fix the button if you have never worked with such equipment before. Failure to do so could damage other components. Better to use the services of a professional or turn on the laptop without a button. Sometimes only the top of the button breaks, while the switch remains intact. To start the device, you just need to press the switch with any convenient object.
Power ON function
It is better to take care of how to turn on the laptop in advance if the start button breaks. In addition, this method will be useful for those who start the system through the Boot Menu. You just need to set certain parameters, and you can turn on the laptop from the keyboard. Follow the instructions:
- Enter BIOS via Boot Menu or in any other convenient way.
Go to “Power Management Setup” or “Power” section. Partition names may vary depending on the BIOS manufacturer.
Find the item “Power ON function” and set the value to “Any Key”.
Thanks to the change in this parameter, the laptop can now be started by pressing absolutely any key on the keyboard. After fixing the Power button, you can return the reverse settings in the same way if this configuration does not suit you.
Today we have analyzed two options, thanks to which the mobile computer is turned on without a corresponding button. Such methods allow NOT to disassemble the device for manual repair and not to carry it urgently to the service center for repair.
Asus laptop turns on and off quickly
Most often, the device turns off immediately after an attempt to turn on due to faults in the cooling system.
- A lot of dust has accumulated in the case.
- Defective coolers.
- Dust completely clogged the radiator grille.
- The thermal grease required for normal cooling of electronic components has dried.
Experts recommend at least once a year to return the device to a service center for prevention. cleaning from dust, replacing thermal paste, diagnostics, setting.
Less often, a short circuit of the north or south bridge, a malfunction of the card, can lead to a shutdown of the computer immediately after it is turned on. Electronic shorts are often caused by liquid spilled onto the keyboard. Although the moisture was quickly removed, a few drops could seep inside and this would inevitably lead to short circuits and malfunction. If the PC has been accidentally flooded with water, tea, wine. you must immediately turn off the power, remove the battery and return the device to a service center as soon as possible for drying and checking its functionality.
Lights are on, fans are noisy, and the laptop won’t start
The device seems to have turned on, the fan rotation noise is heard, but the screen does NOT light up and the HDD indicator does NOT flash.
- BIOS firmware violations.
- Memory or processor problems.
- The north bridge of the motherboard is faulty.
External obstacles to normal operation are first sought.
- If peripheral devices, printer, fax are connected to the computer, cable connections are made. a malfunction of the connected equipment may cause the laptop to be inoperative.
- Disconnect all external connections. At the same time, during the disconnection process, carefully inspect all connectors.
- Damaged or torn contactors, dirt, dust, bent contacts. all this can prevent the device from turning on.
One of the most common reasons that an Asus laptop won’t turn on is due to rough handling of the computer. When moving it with the power supply connected, it is very easy to damage the rather thin, vulnerable connection terminals or break the wires. In this case, it is necessary to replace the connectors or connecting cables.
The laptop will not be able to turn on immediately after being in low temperatures for a long time. According to the instructions, after bringing the PC into the room from the cold, you must wait at least two hours before trying to turn it on. In a warm room, condensation may appear on cold parts, moisture, which will lead to a short circuit and failure of the electronics.
Asus laptop does not turn on: instructions for solving the problem
The difficulty of repairing monoblock computers, in particular, laptops, lies in the fact that the replacement of SEPARATE functional modules is not provided. Therefore, there is little that an ordinary user can do to restore the functionality of the equipment.
If you carefully study the situation, it may well turn out that the reason is quite banal and can be solved without the involvement of masters from the service center. Therefore, first you need to consider in detail what is happening and how exactly the Asus laptop does not turn on.
Laptop starts loading BIOS and then shuts down
Or reboots over and over again. In this case, such problems are possible.
- The south bridge is overheating. Most likely due to a short circuit. Usually this malfunction is preceded by some kind of USB problem.
- The processor overheats due to accumulated dust, incomplete contact of the heatsink. In this case, you can hear the noise of the cooler running at increased speeds.
- The external unit is NOT receiving power and the internal battery is severely DISCHARGED. The laptop has enough power to start, but not enough to work.
If the battery has NOT been infected for a long time, when you turn it back on, the charging progress indicators will glow. But, the device itself will NOT turn on. There is not enough charge power. In this case, you need to wait a while to replenish the energy reserves in the laptop battery.
If no indicators are lit, you need to check the presence of current in the sockets and the correctness of the power supply connection. Is there any external damage to the wires? Are Contact Groups Purpose? If possible, it would be good to check the power supply by replacing it with a known working one.
Laptop turns off during Windows boot phase
If the computer turned on, the BIOS went through all the stages normally, and when the operating system starts up, it crashes and the boot is interrupted. there is a high probability of problems with Windows or a virus infection has occurred. The SIMplest solution is to roll back to factory settings or completely reinstall Windows OS. As practice shows, after violations in the registry or damage to system files due to viruses, it is almost impossible to find the true cause of the problem and it is easier to reinstall Windows. In mild cases, a SIMple rollback of the system to one of the previous states helps.
Laptop does not run on battery
When connected to the network, the laptop’s external power supply turns on, but the internal source does NOT want to work. The following problems are likely here.
- There is no battery, bad contacts. Contacts may break after dropping or shaking the computer.
- The battery is defective and therefore is NOT charging. The unit does not charge due to a malfunction of the external power supply or defective connectors.
- Internal power supply failure.
As you can see, there is very little you can do at home to repair a laptop.
How to check the laptop power button for a malfunction
To make sure that the power button on the laptop does not really work, you need to diagnose it.
To do this, follow a series of steps:
- Disconnect the device from the network;
- We disassemble the laptop. To do this, turning it over, remove the battery, unscrew all the screws on the case, detaching the bottom cover;
- We carry out a visual inspection of the button. In most cases, the button is very SIMple: two contacts are closed when you press on the convex metal diaphragm. Very often, dust accumulates under it, and the contacts themselves become covered with a layer of oxide over time. As a result, when you press the button, the contacts are not closed;
- Ringing out the button. To do this, put the needle tips of the tester on the two contacts of the button and press it. When the button is pressed, the device should emit a characteristic sound signal. If this did not happen, the button does not work;
- We clean the contacts under the metal diaphragm of the button. With tweezers, carefully remove the upper part of the button and, with the help of a contact cleaner, remove traces of oxide and other contaminants;
- Putting the button together and retesting it. In most cases, cleaning the contacts allows you to restore the functionality of the button without replacing.
“alt =” ”
If such manipulations did not give a result, and the button still does not work during testing, a complete replacement is required. For this, the old part is soldered out and a new one is mounted in its place.
Laptop does not turn on from the power button. repair overview
An incomprehensible situation, when the laptop does not show any signs of life when you press the power button, makes the user seriously nervous. A laptop is often used for work, so it becomes unwittingly scary for the fate of the documents stored on it.
Fortunately, these fears are not always justified: in most cases, any malfunction of the laptop, be it a hardware problem or a software glitch, can be corrected without harming the data. over, you can diagnose and eliminate this malfunction yourself.
As practice shows, there may be several reasons why the power button stops starting the laptop. All of them can be divided into two groups. hardware (hardware problems) and software. Let’s consider the most common ones:
PC power failures are the most common hardware problem. Perhaps the laptop battery is completely discharged, and to fix the problem, just put the laptop on charge and wait a little.
- When connecting the power supply, pay attention to whether the power indicator, which is usually located on the front of the laptop case, comes on. If the light is off, then the reason should be looked for in the adapter and power wires.
- In this case, you need to check the reliability of the connection of all connectors, make sure that the socket itself is working. To do this, it is enough to connect any other working electrical device to it. Next, inspect the power cord for damage.
- If the laptop power button is blinking, then this indicates a problem in the power circuit. There is a chance that there is a problem with the internal power supply on the motherboard. In this case, you cannot do without the help of a specialist.
- Battery problems. If the power light is on, but the laptop does not respond to the power button, check the battery. To do this, you need to remove the battery, wait a few minutes and try to start the computer without it. If the reason was in the battery, the laptop will turn on, but it will only work from the mains. In this case, it remains to purchase a new battery.
Lack of initialization is the main programmatic reason.
In this case, when you press the “Start” button, the laptop starts, but does NOT boot to the end. There may be several reasons for this behavior.
The most common ones are damage to the BIOS firmware, overheating of the processor (for example, due to a dust-clogged cooler), boot from the hard disk, etc.
Some problems of lack of initialization can be solved by yourself.
- First you need to disconnect the hard drive and check if the BIOS splash screen appears when you turn on the laptop. If it appears, it means that the hard drive needs repair or replacement.
- You should also check if the RAM fits snugly in the socket (it often comes off when it is hit or vibrated).
Power button does not work.
- The laptop start button itself may also fail during operation. There may be several reasons for this. from trivial wear and tear and dirt to moisture getting on conductive paths (for example, when turning on the computer with wet hands).
- To fix the problem in this case, check the functionality of the button and, if necessary, clean it or replace it.
How to turn on a laptop without a power button
There are several ways to turn on a laptop without a button.
If the computer is disassembled, you can start it by closing the contacts of the Power button with a screwdriver.
However, this method is appropriate only if you need to make sure that the button itself does not work, and not interrupt, say, the loop of the laptop power button.
When you urgently need to start the laptop for work, it is easier to use the second method:
- Start the computer by pressing and holding the Del key;
- In the BIOSa window, go to the Power Management Setup section, which is responsible for setting the computer’s power consumption;
- We select the Power on Function option, which determines the order of turning on the power of the computer;
- To turn on the computer from any key on the keyboard, select “Any Key” in the settings;
- Keeping the specified parameters (F10), press ENTER.
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 CPU overheating due to a dusty 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 can be observed: the device turns on, but quickly goes out due to a dead battery.
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 it is either a hardware or software problem 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.
Laptop won’t turn on. problem solution!
Did you run your laptop for a year or two and stop turning on? Or maybe it did NOT work at all # 128521; 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 repairs are needed “by hand”. And the software can be solved on the spot, do not get up from your chair. This includes problems with BIOS setup, operating system, and programs.
First, let’s define our problem a little. If the laptop won’t 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 the problems that you have. Accurate fault diagnosis is already half of the repair.
Windows starts to load, but everything is bad.
It’s such an 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. “Light” check option. will run from a bootable USB flash drive with Windows. If the laptop with it behaves SIMilarly badly, then it is probably rubbish, you need to carry it for repair. In general, Windows boot problems are a completely different story.
Fans are making noise, but 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 hotkeys for turning on the backlight on your laptop and press them. For example, on many Lenovo models, these are “FnF2” buttons.
The screen may really not work, and there are also various artifacts instead of an image. The surest way to check if the 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 card can often be a prerequisite for a malfunction, especially for those who like to play games on a laptop. Due to a poor cooling system, dust / pollution thereof or misuse of your “friend”, cards overheat and break faster. This is especially true for nVidia 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 manufacturers 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 the card.
So, if the matter is in the card, then try to pull it out, if the design allows it, or turn it off using the switch, which is present on some models. Without a discrete card, “beech” can work, just won’t go Demanding games.
There may be more serious reasons: missing / not working processor or memory, broken BIOS firmware, non-working laptop north bridge (problems with the motherboard).
The laptop does not turn on and does NOT show signs of life
In most cases we have power 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 power.
Most often, the power supply does not work, or it functions defective (here just try a SIMilar working one), bad contacts in the connector, broken or bent wires. Look at the whole thing and draw a conclusion. at what stage the power is lost.
So that there are no problems with the power connector, I advise you to insert the power plug into the laptop first, and then only the power cord into the outlet. By 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 I return the devices in turn, 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 on your own without disassembling the laptop, if it really does NOT show any signs of life 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.
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 default. In different versions this item may be in different places, but the name is approximately the same “Load BIOS Defaults”. the keyword “defaults”. Then I will 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, such as a hard disk or RAM failure. With a certain skill, problems with the Hard Drive can be blindly diagnosed by listening to the laptop # 128578; The working disk, when turned on, spins the engine and crackles for a couple of seconds, read 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 trims, 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 it stopped in another slot.
Let’s sum up
So what if the laptop won’t turn on? First, think about what happened, what was the last time they did it. If you played for a long time, then the card or other chipsets of the laptop probably overheated and a qualified repair is needed here.
If you installed some programs, rebooted and that’s it, then there are most likely errors with Windows. The main problems that can be diagnosed and / or solved by myself, I described in the article. Finally, I would advise NOT to make rash conclusions and DO NOT disassemble the laptop without proper experience.

Repair, service and setup of laptops
The laptop does not turn on, what to do?
If your laptop does not start at all, or it starts but does not load properly, it is possible that you can fix the laptop yourself, rather than resorting to the services of a service center. This article will describe the most common malfunctions and how to solve them.
- Situation 1
The laptop seems to have died. You plug in the AC adapter, but the LEDs (power indicator, hard drive indicator, battery indicator, etc.) do not light up and the laptop does not respond when the power button is pressed.
First of all, in this situation, it is worth checking the outlet, power supply cord and laptop power supply. You can connect a table lamp or other electrical device to test the outlet. Make sure that the power supply indicator on the power supply lights up when connected to a 220V AC outlet. If your power supply does not have an indicator, you can measure the output voltage with a voltmeter. If the outlet is working, and the indicator does NOT light up and there is no supply voltage at the output of the power supply, find a known good mains wire and power supply. It is possible that the laptop appears to be dead due to a faulty power supply and a dead battery. If you know for sure that the power supply is working correctly and is giving the correct output voltage, and the laptop still does not turn on, most likely your laptop has a faulty power controller or power circuit on the motherboard. In this case, the motherboard needs to be repaired. If you have a replacement power supply, make sure you are using the correct one. The output voltage should be exactly the same as on the original adapter. The output current must be the same or higher, but not lower.
- Situation 2
When the power supply is connected to the laptop, the power supply and battery indicator lights up. When you press the power button, the laptop does not turn on, while the sounds of the hard drive, cooling system cooler and optical drive are NOT audible.
If the power indicator comes on, it means the laptop is receiving power from the power supply. Most likely the power supply is working, but just in case, measure the output voltage with a voltmeter and make sure it matches that indicated on the power supply. In this case, the following advice can help: disconnect the power supply from the laptop, disconnect the battery and leave the laptop for 2-3 minutes. After that, connect the power supply to the laptop. Sometimes it helps. If the laptop turns on, the battery is most likely out of order.
Also, this behavior of the laptop may indicate problems with the RAM. Try reinstalling the memory modules, just remove them from the slot and reinstall them. Try installing the memory module in a different slot (if available). If you have two memory modules, try removing them one at a time and the laptop will start with one memory module. If the laptop works with one memory module in both slots and does not work with another memory module in both slots, then the other memory module is defective and needs to be replaced. If the laptop works with both memory modules in slot A and does not work with both memory modules from lot B, then memory slot B is faulty and you will have to change the motherboard, or use only one memory slot.
- Situation 3
When the power button was pressed, the laptop turned on and issued a series of short and long beeps. There is no image on the matrix. Try to search for a faulty memory module as described above, find a known good memory module, most likely an error signal means a malfunction of the memory module or modules. Also, such signals may indicate a faulty chip, which needs to be replaced.
- Situation 4
When you press the power button, the laptop turns on and boots normally (the hard disk LED blinks) but there is no image on the matrix. In this situation, you need to connect your laptop to an external monitor. If there is an image on the external monitor, most likely the laptop has a faulty chip, or a matrix cable, or a matrix. See the article Replacing bga chips.
- Situation 5
When you press the power button, the laptop turns on, but you hear repeated clicking or grinding sounds. Most likely you hear this noise due to a faulty hard drive. Remove the hard drive and turn on the laptop without it, if the noise disappears. the problem is with the Winchester, you need to replace the hard drive. If, when turning on the laptop, you hear repeated clicks or rattling, but the operating system boots, you can test the hard drive with one of the test programs, for example VICTORIA or HD Tune Pro.
- Situation 6
The laptop turns on, loads the operating system and operates normally, but after a while it turns off spontaneously without any reason or warnings. After a reboot, the situation repeats again. Most likely the problem is processor overheating. Listen to the cooling fan, make sure it is working. If the cooler works, then the cooling system is clogged with dust and needs to be prevented. Also, the problem may be in a faulty memory module, use the tips described above. If the laptop loads the operating system, you can run the RAM test, usually using the Memtest86 program Test the RAM and replace the faulty memory module.
We remind you that ASKAND service center maintains and repairs laptops of the entire model range of such manufacturers: APPLE, ACER, ASUS, COMPAQ, DELL, EMACHINES, HEWLET PACKCARD, ROVERBOOK, FUJITSU, MSI, IBM, LENOVO, LG, SAMSUNG, SONY, TOSHIBA.
Windows does NOT start on a laptop. Laptop hard drive NOT working
The laptop turned on, the indicators were blinking, and laconic lines of system information appeared on the screen. That was the end of it. The operating system does NOT load further. The hard drive is most likely to blame for this situation.
Laptop does not initialize
The laptop turned on, the cooler started up, light bulbs flickered, but then nothing happens. The cooler is noisy, but there are images. The problem is most likely in the display. First of all read the article on How to Connect a Laptop to a TV. If there is an image on the external screen, then the problem is with the laptop display. Either the display itself has broken, or a cable that connects it to the motherboard.
If the display is working properly, then the following is likely:
- CPU, memory, or chip problems;
- BIOS problem.
Laptop diagnostics and BIOS reinstallation are best solved in the service center.
Why the laptop won’t turn on?
We will determine the stages of loading the laptop until it is fully turned on. We consider the successful loading of the operating system to be complete. Desktop image is present, mouse and trackpad are working. To get to this point, the laptop goes through several stages:
- Power on;
- Initialization and appearance of the image on the display;
- Loading the operating system;
- A working operating system.
Failure is possible at each stage.
Laptop won’t turn on
There are two options here.
Option 1. Plug in the power supply, but the LEDs DO NOT light up. The laptop does not respond when the power button is pressed. The problem may not be with the computer, but with the outlet. We are trying to connect something to it, for example, a table lamp.
If the socket is working properly, then we check the power supply. The best way. Use a serviceable power supply. If the outlet and power supply are working, then the problem is with the laptop. Defective either the power controller or the power circuit on the motherboard. Such repairs require qualifications and components, so it is better to go straight to the service center.
Option 2. When you connect the power supply on the laptop, the power and battery indicators light up. This means that the power supply is working. But the laptop does not respond to the power button, the cooler and hard drive do NOT show signs of life. Unplug the power and leave the laptop for 2-3 minutes. Then connect the power supply. Should help.
Problems with the RAM appear SIMilarly. Disconnect the computer from the power supply, remove the memory modules from the slots, and then reinstall them. You can install the module in another slot, if there is one. If the laptop has two memory slots, then check their serviceability one by one by running the laptop to one memory module. The check will show whether the problem is in the memory modules or in the slots. If the memory fails, then we buy a new module. Otherwise, we take the laptop to the service center.

The laptop does not turn on and does NOT show signs of life
The worst thing is that an ordinary user of this device can present himself. What to do in this case?
- Often, if the laptop does not start, then the problem lies in its power supply. Therefore, first of all, check if there is a light in the house and voltage in the outlet.
- If there were no problems with electricity, you should proceed to inspect the power supply. Perhaps it began to work intermittently, or it broke completely. The surest way to be sure of this is to get the exact same power supply, only in working order. Connect it to your laptop and track if your device turns on.
- Often, the breakdown of the power supply is very trivial. broken wires or broken contacts in the connectors. By the way, an equally SIMple rule will help to avoid problems with the charger in the future. To charge the laptop, connect the plug first to the device, and only then the adapter cord to the electrical outlet. The fact is that with a different connection order, a spark appears, which spoils the contacts.
- If a SIMilar power unit does NOT save the situation, then it’s time to move on to more decisive actions. Remove the battery from your device, wait 10-15 minutes, and then turn on the device. If it turned on without problems, then secure it and put the battery in its original place.
- Another reason why the laptop does not turn on, sometimes lies in the devices connected to it. Disable all of them, including even the Wi-Fi adapter. Try to start the device again. If the laptop turns on, then I return the external devices one by one to understand which of them provoked the problem.
These are the steps you can take on your own when the laptop is NOT booting. If none of them led to the desired results, then the problem should be looked for in a non-working motherboard, breakage of internal contacts and more. And only an experienced master will help with this.
Turns on and freezes after the splash screen
Sometimes, for some reason, the laptop does not “start” in any way. And sometimes it does start, you can see the initial splash screen and basic information about the device on the screen, and then the device freezes. Either nothing happens at all, or information about errors appears, That interfere with the full operation of the machine.
- DO NOT be scared. Most often, the reason for this is the BIOS settings. You just need to enter the BIOS and reset all parameters. “Load BIOS Defaults”. After that save and exit.
- Sometimes it happens that the laptop freezes, reports a detected error and asks to press a certain button. For example, “Press F1 to continue”. As a rule, after pressing it, it continues to turn on and then works as usual. And although such a solution to the problem is the SIMplest, one should not ignore the very fact of informing about an error. Most often this happens if the battery in the motherboard of the laptop starts to run out or the BIOS settings get lost. Please note that to replace the battery you need to contact the service center.
- Of course, problems with a laptop can be more serious. For example, malfunctions associated with the operation of the hard drive manifest themselves in a SIMilar way. In this case, there is a chance to determine the presence of problems by ear. If the hard drive is faulty, then you hear how the engine tries to start unsuccessfully under a slight crackling of the heads.
- Another reason why the laptop won’t turn on is RAM. Some device models provide access to its trims. You can try removing them and gently cleaning the contacts. If this does not help, then start the machine, leaving only one memory module at a time. In the event that your device has only one bar, then put it in another slot and start the device again. There is a great chance that these actions of yours will help solve the problem.
The laptop constantly reboots or turns off
If your device keeps shutting down and rebooting, it is most likely a serious hardware problem. Perhaps the fault is the short circuit in the south bridge, which caused its overheating. Or dust got into the cooler, which became a prerequisite for excessive heating inside the processor. If so, the fan will run at high RPM, but still WON’T cope with the automotive problem. In total, your laptop will periodically shut down and reboot. This will happen at a variety of times, regardless of external reasons. You are unlikely to be able to solve the problem yourself this time, so immediately contact the service center.
But before that, make sure it’s not a bad diet. If the laptop battery runs out, the device can turn on and then immediately shut down.
A message is displayed about the impossibility to start from the boot device
As a rule, we are talking about a variety of messages in English. If you encounter a SIMilar problem, then Remove all flash drives from the device, and remove the disc from the drive. Restart your laptop. If your actions have not brought any positive result, then the problem most likely lies in the hard drive. Such a malfunction can be of both software and hardware nature.
In the first case, reinstall Windows. If after that your laptop began to work as before, then this means that the problem was software and now it has already been resolved. If reinstalling the operating system did not save the situation, then it’s time to contact the service department, whose employees will solve this malfunction at the hardware level.
Coolers can be heard, but the laptop screen is not working
So, you know what to do if your laptop won’t turn on. But there are also cases when it starts, but its screen remains dark. What to do in this case?
1. Take a close look at the monitor. Perhaps you still manage to consider something? If so, then the screen is most likely in order, but the backlight does not work. You can enable it by using the hot keys on the keyboard. Each model has its own and most users are well known.
2. Another way to check if the screen is working is to connect an external monitor to the laptop. If a picture appears on it, then there is no longer any doubt and the cause of the malfunction is determined.
3. Often the problem is hidden in a discrete card. This element sometimes overheats and breaks down. By the way, some cards are prone to breakage more often than others. For example, nVidia cards have a short lifespan.
To prevent such damage, do not hold the laptop on my lap or in any other position with the ventilation holes covered. It is advisable in such cases to use special stands that DO NOT impede air circulation.
If your laptop is not a gaming laptop, then I do not devote too much time to games on it. And also. do not forget Monitor the temperature of the card. If the reason is in it, then Remove or SIMply Disable it. on some laptop models, switches are specially provided for this. With the missing discrete card, your device will continue to work, you just have to temporarily say goodbye to some games.
Of course, the reason why the laptop boots up and won’t turn on can be more serious. For example, in some cases, the problem is with the processor or firmware, motherboard or memory. But you are unlikely to cope with such difficulties on your own.

After booting Windows shows a black screen error death screen and reboots
Another fairly common problem is when, when you turn on the laptop, Windows starts loading, but then the boot is interrupted and the device restarts. Screen turns blue or black and displays multiple error messages.
As in the previous case, the problem can be of both software and hardware nature. And the concepts of what exactly happened to your device will help Windows again. Reinstallation of the operating system can be started from a bootable USB flash drive. If you succeed in doing this, then the problem can be considered solved. If not, then you can’t figure it out without the help of specialists from the service center.
