In order to determine the cause of your laptop's malfunction, let's determine at what stage of loading your laptop stopped. The following steps can be distinguished:
- Turning on - by pressing the power button, the coolers start to make noise, the lights come on - the indicators for turning on and the CaspLock, NumLock, etc. keys. nothing appears on the display.
- Initialization - images appear on the display.
- Loading the operating system - on the display we see the splash screen installed on your laptop operating system (most likely you see an image with the inscription “Windows”).
- A functioning operating system.
So, find out at what stage your computer freezes.
The laptop does not turn on.
If you press the power button, and the laptop does not react in any way and does not show any “signs of life”, there may be several reasons.
Faulty laptop power supply. This is the first thing you should pay attention to before you get upset and look for money for repairs. Perhaps your charger just burned out, the laptop is discharged and therefore does not turn on. Take an adapter from neighbors or friends, it is desirable that the output volts be the same as yours, and connect the device with it. If everything “went”, then you can buy power supplies for laptops by clicking on the link. And if it didn’t work out, we look for the reason further.
Defective laptop battery. Try removing the battery and plugging the device into an outlet. If the laptop works, take it to the service anyway, perhaps one of the controllers is simply faulty, then you won’t have to buy a new battery.
Faulty laptop motherboard. This is the last and most serious reason for "knocking out" your laptop. There can be many possible reasons for the failure of the motherboard: the inability to boot the BIOS, a short circuit on one of the batteries, a malfunction of the chipset or one of the controllers. Take advantage of warranty service (if any) or take it to a service center where experienced engineers will fix everything.
Laptop won't initialize
Initialization is the activation of the video card, motherboard, processor, RAM and hard drive (hard drive). Simultaneously with this process, a report appears on the display about the passage of all stages of initialization or an image of the logo of the laptop manufacturer.
So, you pressed the power button, the laptop turned on, the cooler started working, the lights on the keyboard blinked and that’s it, you didn’t see the “Windows” logo, the display is black, the cooler continues to make noise. Possible reasons for this problem:
Faulty laptop display. You didn’t see any screensavers, but you heard the sound of logging in - you have a 100% “covered” display. If you have a password to enter the OS, turn on the computer and wait a couple of minutes, then “touch” try to enter the password, did you hear a sound? Then the third option: with a very high probability, the cable from the motherboard to the display does not work. If you are confident in your abilities, disassemble the device and check the cable, if not, take it to a service center, they will find out what the problem is and fix this malfunction.
Laptop hard drive won't start. In the event of a hard drive failure, the device will move beyond the initialization process and hang in search of a hard drive. In this case, you need to contact a specialist to prevent the loss of your data.
In addition to those listed above, your laptop may “hang” at the initialization stage for the following reasons:
There is no contact with the RAM or its absence. It often happens that the contact between the motherboard and RAM is lost. Sometimes, to fix this problem, it is enough to remove and install the bar of RAM back.
BIOS problem. It is solved by reinstalling the BIOS, though you will have to carry the device to a service center for this.
Windows crashed on laptop
This is purely a software problem caused by system file corruption. In this case, you need to reinstall the operating system. But keep in mind that the data that was on the C drive will be destroyed during the reinstallation. To save all the data without exception, as well as to install a licensed OS, they will help you in the service center, so please contact us.
An incomprehensible situation, when the laptop does not show any signs of life when you press the power button, makes the user seriously nervous. The laptop is often used for work, so it involuntarily becomes scary for the fate of the documents stored on it.
Fortunately, these fears are not always justified: in most cases, any laptop malfunction, whether it be hardware problems or software failures, can be fixed without damaging data. Moreover, you can diagnose and fix this malfunction yourself.
As practice shows, the reasons why power button won't start laptop, maybe several. All of them can be divided into two groups - hardware (problems with hardware) and software. Consider the most common of them:
PC power failure- the most common hardware problem. It is possible that the laptop battery is completely discharged, and to fix the problem, it is enough to put the laptop on charge and wait a bit.
- When connecting the power supply, you should pay attention to whether the power indicator, which is usually located on the front of the laptop case, lights up. If the light is off, then the cause should be sought 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 outlet itself is working. To do this, it is enough to connect any other serviceable electrical appliance to it. Next, inspect the power cord for damage.
- If the laptop power button is blinking, then this indicates problems in the power circuit. There is a possibility that there is a problem with the internal power supply on the motherboard. In this case, you can not 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, pause for 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 network. In this case, it remains to purchase a new battery.
The lack of initialization is the main reason for a programmatic nature.
In this case, when you click on the "Start" button, the laptop starts, but does not fully boot. There may be several reasons for such behavior.
The most common ones are damage to the BIOS firmware, processor overheating (for example, due to a cooler clogged with dust), booting from the hard drive, etc.
Some problems of lack of initialization can be solved independently.
- First you need to turn off the hard drive and check if the BIOS splash screen appears when you turn on the laptop. If it appears, then the hard drive needs to be repaired or replaced.
- You should also check whether the RAM is tightly seated in the connector (it often comes off when it is hit or vibrated).
The power button doesn't work.
- The laptop start button itself can also fail during operation. There can be several reasons for this - from banal wear and tear and dirt to moisture getting on the conductive tracks (for example, when turning on the computer with wet hands).
- To fix the problem in this case, you should check the operation of the button and, if necessary, clean or replace it.
How to check the laptop power button for a malfunction
To make sure it's really laptop power button not working need to be diagnosed.
To do this, follow a series of steps:
- Disconnect the device from the network;
- We disassemble the laptop. To do this, turn it over, remove the battery, unscrew all the screws on the case, disconnect the bottom cover;
- We carry out a visual inspection of the button. In most cases, the button is very simple: two contacts close when you press 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 the button is pressed, the contacts do not close;
- We call the button. To do this, put the needle tips of the tester on two contacts of the button and press it. When you press the button, the device should emit a characteristic sound signal. If this does not happen, the button does not work;
- We clean the contacts under the metal diaphragm of the button. Using tweezers, carefully remove the upper part of the button and use a contact cleaner to remove traces of oxide and other contaminants;
- Assembling the button and re-testing. In most cases, cleaning the contacts allows you to restore the functionality of the button without replacement.
VIDEO INSTRUCTION
If such manipulations did not work, and the button still does not work during testing, its complete replacement is required. To do this, the old part is soldered and a new one is mounted in its place.
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 only appropriate if you need to make sure that the button itself does not work, and that, say, the loop of the laptop power button is not interrupted.
When you urgently need to start your laptop for work, it's easier to use another method:
- We start the computer by pressing and holding the Del key;
- In the BIOS window, go to the Power Management Setup section, which is responsible for the computer's power consumption settings;
- Select the Power on Function option, which determines the order in which the computer's power is turned on;
- To turn on the computer with any key on the keyboard, select "Any Key" in the settings;
- We save the given parameters (F10), press ENTER.
It is impossible to imagine our modern life without a portable computer, how convenient and necessary it has become. We can use it at any time and in any place convenient for us. But there are also problems when Acer laptop won't turn on. It all depends on the fact that it is thin, delicate and transportable, but inaccurate actions will only harm it.
If you have no idea why squeaks and refuses to work on battery or directly from a power source, then contact the gsmmoscow service center. Our masters will quickly and efficiently fix all problems. Causes breakdowns, as our experience shows, in most cases appear due to improper operation and negligence. To begin with, you can, if you wish, try to determine on your own why laptop is not working. Check if you are using the original power adapter that came with your Acer. It is also necessary to remove additional USB devices, disks. Now try to turn it on again, if the Acer laptop is working, then these tips will help.
You tried but still laptop won't turn on? Then, most likely, it is not working properly and you should contact the service for professional help.
Reasons why Acer laptop won't turn on.
Firstly, you should take care of the mini-computer, because shocks, strong pops, drops, moisture ingress can severely damage the parts and the Acer laptop can simply fail completely. As a result, after such manipulations, laptop won't turn on.
So, the video chip fails, which naturally needs to be changed.
If the laptop simply does not charge, then the problem may be in the power harness, which will become clear after checking.
The north and south bridges are also replaced when they are not working.
There is another elementary problem in acer- this is a broken power button, it needs to be fixed in order to continue using it.
Due to a broken power connector, you will not be able to use the device until it is repaired.
The laptop does not turn on and through the contact group of the connector, on which there may be damage, in order to resume its operation, it is necessary to contact specialists so that everything is restored.
Problems can also arise from the motherboard, which could be damaged.
So if light bulbs are not on, nothing works, then you should heed the advice of professional help, diagnostics and check it as soon as possible.
Acer laptop won't turn on? Want to know how long the repair will take?
Your laptop turned off and won't turn on, you have tried all the measures, then visit specialists to diagnose possible problems. Diagnostics takes approximately one hour. You will learn for free, for example, why indicators are not lit.
If you are interested in knowing how long the repair will take, then this information is for you. Each type of replacement parts is difficult in its own way, and so is repair. An important role is played by the presence of the desired spare part and the complexity of the model. If your laptop stopped turning on due to a malfunction of the video chip, then its usual replacement lasts about 4 hours. The repair of the board you need can be done in 2 hours. If a light bulb does not light up, and you know that the reason is in the power connector, then we will replace it in about an hour. AT Acer Aspire, for example, the replacement of the south and north bridges lasts from 4 hours.
The professionals of the zhsmmoskov center will qualitatively and reliably bring your Acer portable computer back to life.
A laptop, like everything else, can fail, but if it still doesn’t boot, then it can be great to shake your nerves.
I would advise, first of all, to make sure that the devices are connected and installed correctly:
- is the battery installed correctly in the laptop,
- is it loaded
- Is the power supply fixed, is the power cord working?
If everything is normal, and the device does not want to turn on, it is necessary to analyze what previously performed actions with it could disable it: and mechanical damage. If this has not happened, then you need to observe how the computer behaves at startup and work according to the situation.
Possible problems and solutions.
Below, you can see all the main reasons why the laptop may not boot, as well as self-diagnose your laptop. Hope the tips below help you.
A system reinstall is required.
The computer seemed to start up, the lights came on, a splash screen appeared on the screen, but at the time the Windows operating system was loaded, the laptop freezes and reboots. This situation is the most common. If this is related to the software part, then it is not at all difficult to cure it, I advise you immediately
This can be done both from a boot disk and from a flash drive. But no less common reason for a "tight" freeze is a hard drive failure. In this case, you will need to buy a new hard drive and install it. It's not at all difficult to do this. (Read how to do it)
Problems with the BIOS.
The laptop started up, the indicators lit up, but after 1-2 seconds the device turns off. Here, most likely, there was a physical breakdown, in which case reinstalling Windows will not help here. Such symptoms indicate that the BIOS firmware is incorrectly completed in it. Here you can’t manage it yourself, it’s best to contact the service center, where a specialist on the programmer can completely restore the BIOS to you. Naturally, you can try to restore the BIOS yourself, but the center will install the latest firmware for the required model.
The laptop needs to be cleaned.
If you are sure that the boot program is not damaged, then the problem is in or on the chip on it. There are many reasons here: improper connection of a faulty device via USB, processor overheating, short circuit in bridges or power circuits, etc. I want to suggest conducting and, and at the same time, inspecting all microcircuits for their performance
Hardware malfunctions.
If the laptop is turned on, but the monitor does not turn on, you need to try connecting to a regular TV. If everything works, then the matrix needs to be replaced. If, when turned on to a monitor or TV, no picture is shown, then you need
Blue screen of death.
On the device - a blue screen and nothing starts? This blue color is called the Bsod Death Monitor.
Although the name is terrible, there are also various medicines here, but the main thing here is to find out why this happened? You can learn more. From myself, I can add that 90% of the problems that cause damage to a laptop appear only through the fault of the user. One thing to remember is that you can replace the main devices, replace the thermal paste, clean the laptop yourself, but if you are not confident in your abilities, then take your friend to a service center or call the master at home (if possible) so as not to break the device completely.
A more detailed article “Laptop does not boot. What to do?" located In the video below, you can see how to properly diagnose a laptop if it does not boot. Good luck!
Sometimes there is such a problem that your laptop stops working and you cannot understand what is the reason. Well, that's pretty annoying. Especially if your laptop plays the role of a workplace. In this article, we will tell you what troubles could happen to your laptop.
Different problems can relate to two areas: hardware and program. Hardware problems are when any part of the laptop fails. Software problems are problems that affect the software part of the system. For example, incorrect BIOS, OS or utilities settings.
First you need to understand which area your problem falls into. For example, if your laptop does not even start, then the problem is definitely a hardware one. However, if your unit can get to the BIOS or even start the operating system, then there is a possibility that the problem is software.
Here we need to perform a power check. Throw the power supply to the laptop and be sure to check your outlet. Your device should have a small diode, which indicates that it is connected to the network or the battery is starting to charge.
It is possible that the problem lies in the power supply, damaged connectors or wires. Take a good look at this whole system. In order to prevent various breakdowns, first try to power the laptop, and then connect it to the outlet.
However, if you are convinced and sure that the problem is not in your power supply, then it may be in the batteries. Reconnect the battery. You can also try turning off external devices. After that, turn on your laptop and turn on the disabled things little by little. This will allow you to determine what the problem is.
Strong fan noise, but the screen does not show signs of life
It's possible that your monitor's backlight has simply stopped working. Try to activate it with a keyboard shortcut Fn+F2. If it does not help, then you can throw another monitor to the laptop. With it, you can determine if the problem is in the non-working screen.
Another possible problem is the video card. Quite often we forget to do such basic things as cleaning a laptop. If you are a fairly inexperienced user and have only recently begun to get acquainted with such a thing as a laptop, then know that it needs to be cleaned regularly. Also be sure to keep an eye on the temperature.
Of course, there are more serious problems. For example, problems with the central processor, RAM, BIOS, etc.
Starts up, splash screen displays, or displays a message and freezes
The root of this problem is most likely the BIOS, or rather, its settings. Try to set the default settings in it. This function in different BIOSes can be located in different places, but its name usually looks something like this - Load BIOS Defaults.
It is also possible that you saw the message “Press F1 to continue” while booting the system. This problem usually occurs when the battery on the motherboard (not the main battery) lands, the wrong time is set, or the BIOS settings get lost. To change the battery, you must contact the service center.
Another problem may be the hard drive. It is possible to determine the correct operation of the hard drive by its sound. When starting up, the hard drive makes a couple of crackles, but when something is not right with it, there are much more crackles and everything freezes.
There is also a problem with RAM. If possible, disconnect the RAM and clean its contacts. If you have more than one bar, then try disabling one of them.
Constant reboots or shutdowns
This is most likely a hardware issue. Most likely there was a short circuit that overheated the south bridge. In most cases, this is due to breakdown through USB.
As mentioned above, be sure to clean your laptop. Due to a lot of dust, your CPU can get very hot. In this case, you may hear a loud fan hum and experience constant reboots.
Unable to start from boot disk
With this error, you may receive messages like ". Try removing the flash drive from the laptop, remove the disk from the drive and reboot. If this does not help, you can try reinstalling the operating system. Well, if this did not solve the problem, then you will have to carry your “friend” to the service center.
Found a typo? Select the text and press Ctrl + Enter
The laptop turns on, but does not boot - what to do? This is a natural question that, along with a sense of impending panic, arises for everyone who finds himself in a similar situation. To begin with, you should calm down, put aside the panic and try to start it again: disconnect from the network and after a couple of seconds reconnect the power. If the laptop does not boot after rebooting, then the problem may be serious. A variety of parts can fail:
- Power Supply;
- Video card;
- RAM;
- Winchester.
But there are less terrible problems:
- BIOS failure;
- Software failure;
- accumulation of dust;
- lack of power;
- Disconnecting contacts in bridges.
The easiest way to accurately determine the cause and eliminate it is to contact. But you can go the hard way: do everything yourself. And the first step to this can be booting Windows from a USB flash drive. Although even here you can fail.
Laptop won't boot from flash drive
If you are trying to revive the device using a USB drive, but it does not work, do not rush to despair. Try restarting the laptop or using a different port to connect. If after that the laptop does not boot from a USB flash drive, then most likely the BIOS simply does not enable such a function to boot from a USB drive. Check for its presence: go to the BIOS and select Advanced Features there, and in the window that appears - Boot Sequence. If the system sees a flash drive, then it will be in the list that appears.
To activate the download, move the line with the USB device to the first place in the list and press F12 on the keyboard. If after that the laptop turns on, but does not boot, then pay attention to the sounds: is there any extraneous noise when turned on?
Laptop won't boot and beeps
When downloading, any sounds that the device produces are better than nothing. Silence may indicate the complete and final death of the laptop. Usually, if the laptop beeps, but does not boot, then the BIOS makes sounds and you can use them to determine exactly where the problem happened. Consider the set of sounds in the Award BIOS. At AMI Bios it is similar, but somewhat truncated.
A short single signal indicates that the system is working properly. After it, the normal boot should continue. If the laptop does not boot, what should I do? Nothing special: contact a laptop repairman because your device's video card has failed. This is evidenced by a single signal of the system.
Two short beeps - not a clear, but encouraging sign. So the system talks about disconnecting cables, contacts and other minor problems. To quickly eliminate them, you need to contact computer repair in Krasnodar.
Three beeps - keyboard error. And a complex combination of 1 long and 9 short signals indicates the impossibility of reading data from the disk drive.
In the mobile age, few people still use desktop computers - I increasingly replace them with laptops hp pavilion / compaq / probook, asus, acer aspire, lenovo yoga, samsung, dell inspiron, msi, toshiba, sony vaio, packard bell, dns, emachines , irbis, prestigio, fujitsu, digma, haier, iru, aker, xiaomi, fan, haier, 4good light am500, siemens, h, alienware, brother, dexp, neck and others.
These are extremely useful devices, but they can also sometimes fail to turn on. What to do if the laptop does not turn on - just a black screen is on and that's it?
The situation when the laptop does not turn on at all is not at all uncommon. I met such a defect in laptops asus d541n, k750j, x551m, m50s, k52d, f3, f5r, x751m k50af x52n, k52n, n550, lenovo g500, g50, g505, g700, g580, b570e, g565 v590, samsung r550, ncp r425 r528 np300e5c rv508 np350 hp pavilion g6 m6 dv6 g62 dv7 g62 g7 625 g7 2300er 6715 probook 4730s omen bcm943142y 571g, v3 571g, e531g, v5we2, toshiba l40w, satellite l300, emachines e642g, d620, dell inspiron 15, vostro 15 3558, haier hi133, msi vr330x, cx620, alienware m17x, iru jet 1521, sony 1goodsv, lg50 am600, dexp athena t132.
Only you should know that there can be many reasons for a laptop not turning on - some of them are trivial and easy to fix, others are related to the graphics card and even replacing the motherboard.
Therefore, in my guide on what to do if the laptop does not turn on - only a black screen, I have collected the most common causes and solutions.
The laptop does not turn on at all - check the power
Please note that this can be either an old or a new laptop. You press the "On" button, wait and ... it does not turn on - the device does not respond to our actions, even if we try to turn it on once, twice or 5 times.
Relax and start by eliminating the obvious causes. A black screen in a laptop can be caused by a dead battery.
Then you need to connect the power source, only sometimes the laptop does not turn on when working from the network, but this does not mean that it has already come to an end.
You need to carefully check the power source and socket in the laptop and even the electrical outlet.
You need to look at the cable, whether it is damaged, whether it is worn out and in what condition the plug in the power socket.
If you have the opportunity, try running it on a different battery or power supply. The use of non-original, as well as cheap power supplies can sometimes lead to a short circuit - this is not always the case, but many confirm.
If the power supply is on but the laptop won't turn on, turn it on again, but this time listen to how it reacts.
You need to check if the hard drive and fans are working. It is also worth looking to see if the light diodes (indicators) are on, confirming the start.
Most often, when you hear the sounds of running components, and the laptop does not turn on, or to be more precise, you see only a black screen, it is very likely that you will need to replace the video card.
Black screen on laptop and does not turn on - what to do
As I wrote above, the reasons why laptops do not turn on can be very prosaic, but, unfortunately, this is not always the case.
It happens that a hardware failure will occur - then you will have to take into account significant costs. A black screen in a laptop can be precisely for this reason.
If you hear component sounds when you press the power switch, connect an external monitor (maybe a modern TV) to the VGA or HDMI jack. This procedure will get you closer to figuring out what is causing you to see only a black screen.
If the image appears on the external screen, this means that you do not need to change the video card - it works and interacts correctly with the monitor. In this case, you need to check the operating system settings.
Perhaps the screen was simply turned off and the connection to an external monitor was activated. The contacts in the case that connect the screen to the rest of the computer could also be damaged.
What to do if there is no image on an external monitor connected to a laptop? There are many signs of video card failure. What to do in this situation?
Laptop does not turn on - replace the video card
A faulty graphics card can be a serious problem. In this situation, it seems to us that the laptop is not working, but in fact it works, but does not display an image on the screen.
The thought immediately arises of replacing the old card with a new one. The problem is that on most laptops it is impossible to replace the video card yourself.
On many models, especially low-end ones, graphics cards are integrated into the motherboard in the form of a BGA chip.
To replace it then you will not only need a lot of knowledge, but also the appropriate equipment.
More expensive ones have separate graphics cards, but even in this case, replacing this module will be a difficult job.
As a rule, replacing it without special tools borders on a miracle. Then the only option is to use the services of a professional, trusted repair service.
Replacing a graphics card is so complicated that you may need to first remove the hard drive, Wi-Fi module and matrix, keyboard, and GPU cooling.
As you can see, to get to the graphics card, you need to disassemble most of the device, and after that you need to put it all together.
There may be other damage that will result in your laptop not being able to turn on. Sometimes the motherboard needs to be replaced.
Laptop turns on and won't boot up
The source of this problem may be the BIOS, or more precisely, its settings. Try to set the default settings.
This function can be in different places in different BIOSes, but its name usually looks something like this: "default BIOS settings".
It is also possible that after starting the system, you saw the message "Press F1 to continue".
This problem usually occurs when the battery is installed on the motherboard (not the main battery), shows incorrect time or BIOS settings.
Another problem could be the hard drive. You can determine if it makes a squeak or cracks.
It could also be a RAM issue. Perhaps you just need to disconnect the RAM memory and clean the contacts.
Laptop won't turn on - constantly restarting or shutting down
Most likely, this is a hardware problem, not always, sometimes reinstalling windows 10, windows 7, windows 8 or windows 8.1 (depending on which one you use) solves it.
Hardware problem, may be due to high dust content in the processor. In this case, you may hear a loud fan noise and notice a constant reboot.
When you hear the sounds produced by the device, it's better than nothing. Silence can indicate the total and final death of the laptop.
Usually, if it squeals but does not start, the sounds are produced by the BIOS, and thanks to them you can pinpoint where the problems are. Consider the set of sounds in the BIOS Award system. AMI Bios has a similar one.
A short single beep means the system is working properly. After that, it should continue with a normal start.
Two short beeps is an encouraging sign. The system indicates minor malfunctions.
Three beeps - keyboard error. A complex combination of 1 long beep and 9 short beeps indicates that data cannot be read from the disk.
Laptop Won't Turn On - BIOS Issues or Hardware Errors
The mobile computer starts up, the indicators are on, but after 1-2 seconds the device turns off. Most likely, in this case, a physical failure. Reinstalling Windows won't help here.
Such symptoms indicate that something is wrong with the BIOS and it may need to be restored.
If you are sure that the bootloader is not damaged, this indicates a problem with the motherboard or microchip.
There are many reasons: improper connection of a faulty device via USB, processor overheating, short circuit, and others.
Reasons why the laptop does not turn on
Shocks, drops, moisture penetration can seriously damage parts, as a result, after such manipulations, the laptop does not turn on.
There is another elementary problem - this is a broken power button, fix it to continue using it. Due to a broken power connector, you will also not be able to use the device.

Can't describe everything. I look at the record and it turned out far from small. If you did not find help in this article, write in the comments and I will try to provide you with individual assistance.
For some people, a laptop is such a necessary thing that when it does not turn on, they feel hopeless. If you turn on the laptop, and it does not show signs of life, then do not rush to panic. In this article, we will talk about what you can do if such a trouble occurs.
All problems with a laptop are divided into two groups: software and hardware. The first can be solved immediately without getting up from your chair. This includes problems with programs, the operating system, and BIOS settings. If the second appears, then repairs are needed.
Freezes showing splash screen
Above, situations were described when the laptop stopped turning on. What to do if it freezes? In this case, an initial splash screen or some text may appear. Nothing happens next, the laptop writes about an error or beeps. Most likely, this is a problem with the BIOS settings. You need to enter it and reset the settings. This item may be in different places in different versions, but it has the same name and contains the defaults keyword. Then save the settings (save) and exit (exit). Please note that the system may report an error, but further loading is possible. You just need to press the F1 button. This usually happens when the battery on the motherboard is dead. At the same time, BIOS settings and time are lost. It needs to be replaced (either by yourself or at a service center).
This also includes the situation when, after the update, the laptop does not turn on or freezes. Reinstalling the system will help here. It's better to turn off automatic updates and choose only those that you really need.
What to do if the laptop does not turn on (or rather, does not boot) after you have used the above tips? Then the problems may be due to RAM or hard drive. And this is much more serious. For some laptop models, access to RAM is not closed. It is worth removing the straps and carefully clean the contacts. A problem with a hard drive can be diagnosed by its clicks during information transfer.
Doesn't boot from disk
This can be signaled by inscriptions from the screen in English. For example, Error loading operating system or something similar. First, turn off all external devices (flash drives, disks, etc.). Then reboot. If it does not help, then this is either a software or hardware problem of the hard drive. The first can be solved by contacting a service center, where they know exactly what to do if the laptop does not turn on. The second is by reinstalling the operating system.
Conclusion
So what to do if the laptop does not turn on? The reasons may be different. To begin with, it is worth considering at what point this happened. That is, what last actions could lead to a breakdown. If it was a long game, the graphics card or other laptop chipsets probably overheated. This will require a qualified repair. If some program was installed, and after the reboot the laptop did not turn on, then these are operating system errors.
The most common problems and ways to diagnose them were described in the article. And finally: do not make rash conclusions and do not disassemble a laptop without having the appropriate knowledge.
