Laptop does not turn on at all. check 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 reasons. Black screen in laptop can be caused by full battery discharge.
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 the end of life.
You need to carefully check the power supply and socket in the laptop and even the electrical outlet.
You need to look at the cable, and whether it is damaged, not worn out and in what condition the plug in the power socket.
If you can, try running it on a different battery or PSU. 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 and 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 seeing if the light diodes (indicators) are on, confirming the start.
often than not, when you hear the sounds of running components and the laptop does not turn on, or to be more precise, you only see a black screen, it is very likely that you will need to replace the card.
Reasons why the laptop does not turn on
Shocks, falls, moisture penetration can seriously damage the parts, as a result, after such manipulations, the laptop does not turn on.
There is one more elementary problem. a broken power button, fix it to continue using it. Due to the broken power connector, you will also not be able to use the device.
Laptop won’t turn on. constant restart or shutdown
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 general and final death of the laptop.
Usually, if it screeches, but does not start, the sounds are produced by the BIOS, and thanks to them, you can pinpoint where the problems are. Let’s consider the set of sounds in the BIOS Award system. In AMI BIOS SIMilar.
A short single beep means the system is working properly. After that, it should continue with a normal start.
Two short beeps are a reassuring sign. The system speaks of minor faults.
Three beeps. keyboard error. A complex combination of 1 long and 9 short beeps indicates that the data cannot be read from the disk.
Black screen on laptop and won’t turn on. what to do
As I wrote above, the reasons why laptops won’t turn on can be very prosaic, but unfortunately this is not always the case.
There are times when a hardware failure occurs. then you have to take into account significant costs. A black screen in a laptop may be for this very reason.
If you hear sounds of operating components when you press the power switch, connect an external monitor (maybe a modern TV) to the VGA or HDMI jack. This procedure will bring you closer to figuring out what makes only a black screen see.
If the image appears on the external screen, it means that you do not need to change the card. it works and interacts correctly with the monitor. In this case, you need to check your operating system settings.
Perhaps the screen was SIMply turned off, and the connection to an external monitor was activated. Pins in the case connecting the screen to the rest of the computer could also be damaged.
What if there is no image on an external monitor connected to the laptop? There are many signs of card failure. What to do in this situation?
Laptop won’t turn on. BIOS problems 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 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: incorrect connection of a defective device via USB, processor overheating, short circuit, and others.
The laptop turns on and does NOT boot further
The source of this problem could be the BIOS, or more precisely, its settings. Try to set the default settings.
This function may be in different places in different BIOS, but its name usually looks something like this: “default BIOS settings”.
It is also possible that after starting the system, you see the message “Press F1 to continue”.
Usually this issue occurs when a 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 emits a squeak or pops.
There could also be a problem with the RAM. Maybe you just need to turn off RAM memory and clear contacts.
7 proven reasons why your laptop won’t turn on
In the mobile age, few people still use desktop computers. they are increasingly replacing them with laptops hp pavilion / compaq / probook, asus, acer aspire, Lenovo yoga, Samsung, dell inspiron, MSI, good, sony vaio, packard bell, dns, emachines. irbis, prestigio, fujitsu, Digma, haier, iru, acker, xiaomi, fan, haier, 4good light am500, siemens, hi, alienware, brother, dexp, nek and others.
These are extremely useful devices, but they can also sometimes NOT turn on. What to do if the laptop does not turn on. just the 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 have seen such a defect in ASUS d541n, k750j, x551m, m50s, k52d, f3, f5r, x751m k50af x52n, k52n, n550, lenovo g500, g50, g505, g700, g580, b570e, g565 в590, np350, samsung r540e r425, r528, np300e5c, rv508, np350, hp pavilion g6, m6, dv6, g62, dv7, g62, g7, 625, g7 2300er, 6715, probook 4730s, omen, bcm943142y, compaq cq58, presario cqire e15, acer 571g, v3 571g, e531g, v5we2, toshiba l40w, satellite l300, emachines e642g, d620, dell inspiron 15 vostro 15 3558, haier hi133, ISI vr330x, cx620, alienware m17x, iru jet people am 1521, sony, sve11501b11. dexp athena t132.
Only you should know that there can be many reasons that the laptop does not turn 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.
Laptop does not turn on. replace card
A malfunctioning 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 idea immediately arises of replacing the old card with a new one. The problem is that on most laptops it is impossible to replace the card yourself.
On many models, especially low-cost 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 corresponding equipment.
The more expensive ones have separate graphics cards, but in this case, replacing this module will not be an easy 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, proven repair service.
Replacing the card is so difficult 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 map, you need to disassemble most of the device, and after that you need to fold it all.
There may be other damage that will lead to the fact that your laptop will not be able to turn on. Sometimes the motherboard needs to be replaced.
Table of the most common software and hardware failures
Below you will find the most common problems with a laptop with a description and recommended solution to the problem.
That’s all. I tried to PROVIDE the main reasons why the laptop does not turn on the toshiba satellite laptop, irbis, Samsung, Sony Vayo, dell inspiron, Acer aspire, emachines, prestige, del, dns, Packard bell and others.

DO NOT describe everything. I watch the recording and it turned out far from small. If you DIDN’T find help in this article, write in the comments and I will try to GIVE you personalized help.
How to connect an external monitor
For this, you will additionally need a cable, it must correspond to the interfaces on the external monitor and laptop. Usually, new devices no longer have an outdated VGA interface at all, but there is a modern HDMI.
I can further recommend the following order of their connection:
- Connect the laptop and monitor with a cable;
- Connect the devices to the mains;
- The monitor should turn on first, then the laptop.
If the image is normally loaded onto the monitor, set the transfer mode on the laptop by SIMultaneously pressing Fn and one of the F1. F12 function keys, depending on the manufacturer. It usually shows a schematic of a monitor and a laptop. This button is responsible for displaying the image. on a laptop, on a monitor, or feeds it to both devices.
How to turn on a laptop if it does not turn on in the usual way
The laptop does not turn on and does NOT boot for various reasons. hardware or software. It often fails to start due to an OS problem, BIOS malfunction, or after malicious applications are running. Next, we will tell you why the laptop does not turn on, and also describe the ways to eliminate most of the problems due to which the device does NOT boot.
If it was not possible to find signs of laptop life on the external device, but all the indicators are on, a common cause of failure is a discrete card. Due to the frequent launch of “heavy” applications, games, poor cooling system and strong dustiness of the device, the cards overheat and quickly fail.
Therefore, in order to extend their life, and not working on a laptop, sitting on a sofa or bed (this is how you close the ventilation grilles), and for “heavy” games, purchase a special laptop stand with built-in additional fans.
You can fix the problem either by replacing the burned-out module, or SIMply by disabling it. If it turns off, then the integrated graphics will work normally, but serious games on the laptop will NOT work anymore. Switching can be done in the BIOS by setting the Disable parameter for the Burnt card. In addition to the described malfunctions, the device is often loaded due to the inoperability of the processor or motherboard.
Solving software problems preventing the laptop from turning on
When suspicion does NOT fall on any physical module, you can try to repair or reinstall the OS to fix the problem. This will require installation media or recovery disc (it is created directly on the system).
Boot Loader Repair
If, when attempting to boot, the display shows that the operating system is in general Tenders, you just need to restore the bootloader. Usually, SIMilar problems arise when installing a second, older OS. For example, when the computer already has Windows 8.1 installed, and you put “sevens” as an additional one, then problems with their loading are guaranteed.
True, the solution is quite SIMple:
- Boot from the installation media;
- Run the command timeline in the initial setup window by pressing Shift and F10 at the same time.
To fix the problem, enter the following commands in sequence:
- Bootrec / FixMbr. a new boot record is created;
- Bootrec / FixBoot. new boot sector;
- Bootrec / ScanOS. search for all installed Windows;
- Bootrec / RebuildBcd. add information about found OS to the boot store.
After restarting, Windows should start.
Determining the source of the problem
I can immediately make a reservation that by the nature of the malfunction, it is almost always possible to determine exactly which part of the laptop needs repair. Analyzing the behavior of the device immediately after switching on can tell more:
- If the laptop is completely disconnected, and when you press the power button does NOT want to turn on and does NOT show any signs of life at all, the indicators are off, then this is definitely a hardware problem. In this case, you will have to change individual modules of the device.
- When it starts up, the light is on, after which it crashes when loading Windows, then this problem can be a software problem, which can sometimes be solved very easily.
Understanding the problems, as a result of which the laptop still does not turn on is already half the way to solving them.
The laptop does not respond when the power button is pressed
So, because of which there are no signs of the life of a laptop at all. mainly power problems. I can advise further immediately to exclude the obvious things, for example, check if the device is receiving voltage. Why just Connect the power supply to the mains. most adapters have a light bulb.
If it is on, then the device is working properly. The laptop also has indicators that are on, showing that the device is connected to the network.
When the light does not light up and does not show signs of life, then this indicates an inoperative power supply. Sometimes the lights are off due to loose connectors. It is quite easy to extend the life of a power supply unit. you need to turn on, first insert the plug from it into the laptop, and then connect the device to the network. So the spark does not light up when connected, because of which the contacts fail more slowly.
In the case when all the indicators are on when turned on, the problem may be in other devices. I can advise you to follow these steps:
- Remove the battery from the laptop and connect the device to the mains through the power supply without it. If the laptop starts up, the light is on, then the exit is to buy a new battery.
- If the laptop does not show signs of life, put the battery back.
- Disconnect external devices.
If, after turning them off, the indication lights up normally, the laptop is working, connect external devices one by one. this way you can determine what caused the failure.
Laptop won’t boot, but fan noise is heard
Sometimes the laptop will not turn on due to a non-working screen, although the device boots. The backlight may just not be on. To enable, you can use “hot” keys. Their usual combination is the Fn button, pressed SIMultaneously with F2, F4, F5, etc. Depending on the model and manufacturer of the laptop.
Sometimes the monitor itself is NOT promising, and instead of the image, all kinds of artifacts can be displayed on the screen.
To check if only he is really faulty, the laptop should be connected to an external monitor.
Malfunctions other than allowing the laptop to boot
When there are problems with the fact that the hard drive has stopped working, they can also be diagnosed by some signs. To do this, just listen to the life of the HDD. the engine can spin the disk for too long in unsuccessful attempts to read information, the heads can also crackle cyclically for a long time. After that, he generally “hangs”.
When the message “Error loading operating system” or something SIMilar is displayed during boot, the problem may also be caused by a hardware or software failure of the hard disk. However, usually the reason for the impossibility of loading in this case is a flash drive forgotten in the USB connector or an optical disc in the drive.
An endless cyclic reboot of the laptop even before the OS is loaded happens due to problems with the motherboard. This may be the overheating of the south bridge or a short circuit. They are often sourced from USB breakdown. Poor operation of the power supply can cause the problem of quickly turning off the laptop immediately after starting the download. it goes out due to the fact that the battery SIMply stopped charging.
The laptop does NOT turn off. How does it happen?
And it happens like this: the laptop is frozen, And does not respond to user attempts to reach it. Another option. The standard shutdown procedure through “Start”. “Shutdown” does not lead to the desired result. The machine begins to execute the protocol, saves data to disk, but does not turn off, but continues to work further or, again, SIMply hangs.
It happens that the screen goes out, but at the same time the noise of the cooler and the glow of the indicator indicate that the system continues to work.
Why the laptop does not turn off?
There may be several reasons. They are universal, that is, they can lead to the fact that an asus, dell, lenovo laptop, tablet or personal computer does NOT turn off.
Lots of applications
A long shutdown of the laptop can be the result of many applications running. And you may not notice some of them if they are in startup and running in the background. The OS begins to close, saving their data, respectively, the more programs are running, the longer the shutdown process takes.
It can be provoked by any program that does not allow the laptop to turn off. Usually this is a process that the system does not terminate due to blocking or freezing. SIMilar problems can be caused by a virus, only in this case the program is not necessarily malicious, but SIMply does not find a common language with the system.
With the advent of new versions of the most popular operating system, it is quite common for a laptop with windows 8 or windows 7 to NOT turn off.
In most cases, this is a consequence of updated raw versions of programs and driver installations, which the system often performs by default. In this case, both rollbacks to previous working versions and installing additional drivers can help. In each case, our laptop repair specialists will determine the optimal solution and ensure normal compatibility and system performance.
When a laptop does NOT turn off in Windows 7 or Windows 8 and newer, the problem may be rooted in the overall system state. Usually this can be judged by the speed of the system as a whole. Programs and applications slow down, the system regularly freezes, and does not immediately respond to user actions. Usually a laptop with a cluttered OS still turns off, but it takes a long time. If not, then the files that are responsible for performing this task could have been damaged directly.
Bad programs are one of the most common causes of blocking system processes. They can be introduced into existing processes, preventing their termination by the OS side. This means that the computer or laptop works, but does not turn off.
Antivirus is NOT a guarantee against getting such a virus.
The cardinal solution is to reinstall the system, but even it does not always save you from viral metastases, which can infect disks and processes. Our specialists can win the battle with him.
In a sense, this problem is one of the variations of the systemic conflict.
Problematic drivers disrupt the operation of devices, which is why there are problems with shutting down the laptop.
Also, one of the reasons may be a problem in the operation of the cooling system, in this case it is recommended to carry out a complete cleaning of the laptop.
Laptop does not respond to charging connection
As noted in the previous section, the lack of reaction of the laptop to the connection of the power supply (both when turning on and when the laptop is turned off) may be the result of problems with the power supply or the contact between it and the laptop. In more complex cases, problems may be at the level of the power circuit of the laptop itself. If you cannot diagnose the problem yourself, it makes sense to contact the Repair Shop.
ACPI and Chipset Drivers
Regarding problems with battery drivers, power management and chipset Several options are possible.
The first method may work if charging worked yesterday, but today, without installing the “big updated” Windows 10 or reinstalling Windows of any versions, the laptop stopped charging:
- Go to the device manager (in Windows 10 and 8 this can be done through the menu by right-clicking on the “Start” button, in Windows 7 you can press the WinR keys and enter devmgmt.Msc).
- In the Batteries section, look for Microsoft ACPI Compliant Battery (or a SIMilar device). If the battery is not in the device manager, this may indicate a malfunction or lack of contact.
- Right-click on it and select “Delete”.
- Confirm deletion.
- Reboot the laptop (Use the “Restart” item, not “Shutdown” and then turn on).
In cases where the charging problem appeared after reinstalling Windows or an updated system, missing original chipset and power management drivers from the laptop manufacturer may be a prerequisite. over, in the device manager, it may look as if all the drivers were installed, and there are no updates for them.
In this situation, go to the official website of your laptop manufacturer, download and install the drivers for your model. These can be Intel Management Engine Interface drivers, ATKACPI (for Asus), individual ACPI drivers, and other system drivers, as well as software (Power Manager or Energy Management for Lenovo and HP).
Battery is connected, not charging (or Charging fails in Windows 10)
Perhaps the most common variant of the problem. in the status in the Windows notification area, you see a message about the battery charge, and in parentheses. “connected, not charging.” In Windows 10, the message looks like “Charging not in progress.” This usually indicates software problems with a laptop, but not always.
Battery connected, charging (but NOT actually charging)
“Modification” of the problem Described above, but in this case, the status in the Windows notification area shows that the battery is charging, but in fact it does not happen. In this case, you should try all the methods that were described above, and if they DO NOT help, then the problem may be:
- Defective laptop power supply (“charging”) or lack of power (due to worn components). By the way, if there is an indicator on the power supply unit, pay attention to whether it is on (if not, there is clearly something wrong with the charging). If the laptop does not turn on without a battery, then the matter is also probably in the power supply (but it could also be in the electronic components of the laptop or connectors).
- Faulty battery or controller on it.
- Laptop Connector or Connector Problems Chargers. Oxidized or Broken Contacts, etc.
- Problems with the contacts on the battery or their corresponding contacts on the laptop (oxidation and the like).
The first and second points can be a prerequisite for charging problems even when no charge messages appear in the Windows Media notification area (that is, the laptop is running on battery power and “does not see” that the power supply is connected to it ).
Laptop is NOT charging
In this material, in detail about the possible reasons that the battery is NOT charging on the laptop and in possible ways to fix it, the normal process of charging the laptop returned.
Note: Before starting any action, especially if you have just encountered a problem, make sure the laptop power supply is connected to both the laptop itself and to the mains (outlet). If the connection is made through a surge protector, make sure it has not been disabled with the button. If your laptop power supply consists of several parts (usually there are) that can disconnect from each other. Disconnect them, and then reconnect them tightly. Well, just in case, pay attention to whether other electrical appliances powered by the network in the room work.
Overheating of the battery
The above “not always” refers to overheating of the battery (or a faulty sensor on it). if overheating, the system stops charging, as this can harm the laptop battery.
If the laptop just turned on from the off state or hibernation (to which there were no charger connections during this) is charging normally, and after a while you see a message stating that the unit is not charging, the reason may be the battery overheating.
The battery is NOT charging on a new laptop (suitable as the first method for other scenarios)
If you have purchased a new laptop with a pre-installed licensed system and immediately found that It does not charge, this can be either a disadvantage (although the probability is not high) or an incorrect initialization of the battery. Try the following:
- Turn off your laptop.
- Disconnect the “charging” from the laptop.
- If the battery is removable. Disconnect it.
- Press and hold the power button on the laptop for 15-20 seconds.
- If the battery was removed, reinstall it.
- Connect the laptop power supply.
- Turn on your laptop.
Helpful The described steps are not often, but they are safe, easy to perform and a lot of time will be saved if the problem is solved right away.
Note: there are two more variations of this method.
- Only in the case of a removable battery. disconnect charging, remove the battery, hold down the power button for 60 seconds. Connect the battery first, then the charger and do not turn on the laptop for 15 minutes. Enable after that.
- The laptop is turned on, charging is turned off, the unit is not removed, the power button is pressed and held until it turns off completely with a click (sometimes it can be absent) for about 60 seconds, connect the charging, wait 15 minutes, turn on the laptop.
Reset and update BIOS (UEFI)
Very often, certain problems with laptop power management, including charging, are present in early BIOS versions from the manufacturer, but as such problems appear in users, they are eliminated in the BIOS update.
Before updating, just try to reset the BIOS to factory defaults, usually using the “Load Defaults” or “Load Optimized BIOS Defaults” options on the first page of BIOS settings (see How to enter BIOS or UEFI in Windows 10 How to reset BIOS).
The next step is to find downloads on the official website of your laptop manufacturer, in the “Support” section, download and install an updated BIOS version, if available, specifically for your laptop model. Important: carefully read the official instructions for updating the BIOS from the manufacturer (they are usually found in the downloadable update file as a text or second document file).
A couple more nuances that may be useful in the context of charging a laptop battery:
- In Windows 10, the message “Charging is not in progress” may appear if the laptop is disconnected from the network with a charged battery and after a short time, when the battery has not had time to be seriously discharged, reconnect (in this case, after a short time, the message disappears).
- Some laptops may have an option (Battery Life Cycle Extension and the like) to limit the percentage of charge in the BIOS (see the Advanced tab) and in proprietary utilities. If the laptop starts to report that the unit does not charge after reaching a certain level of charge, then most likely this is your case (the solution is to find and disable the option).
In conclusion, I can say that in this topic, comments from laptop owners with a description of their solutions in this situation would be especially useful. they could help other readers. At the same time, if possible, we inform you of the brand of your laptop, this may be important. For example, for Dell laptops, the method with updating the BIOS on HP is more often triggered. turning off and then turning on as in the first method, for ASUS. installing official drivers.
Freezes, showing splash screen
Above, situations were described when the laptop stopped turning on. What if it freezes? In this case, an initial splash screen or some text may appear. Then nothing happens, the laptop writes about an error or beeps. This is most likely a problem with the BIOS settings. You need to enter it and reset the settings. In different versions, this item may be in different places, but it is called the same and contains the keyword defaults. Then save the settings (save) and exit. Please note that the system may report an error, but further downloads are possible. You just need to press the F1 button. This usually happens when the battery on the motherboard runs out. At the same time, the BIOS settings and time get lost. It needs to be replaced (either by yourself or at a service center).
This also includes the situation when the laptop does not turn on after the update or freezes. Reinstalling the system will help here. It is better to turn off the automatic updates function and choose from them only the ones that you really need.
What if the laptop won’t turn on (or rather, NOT boot) after following the tips above? Then the problems may be due to RAM or Hard Drive. And this is much more serious. Some laptop models do NOT have access to RAM. It is worth removing the strips and carefully cleaning the contacts. The problem with the Hard disk can be diagnosed by clicking it while transferring information.
Does not turn on (there are signs of life)
In most cases, these are power problems. Check the tightness of the connection of the contacts and the presence of voltage in the socket. Usually, on the laptop and its adapter there are indicator lights, which are lit if there is no breakdown. Most often, the problem is in the power supply, which is functioning defective (there is a contact in the connector, wires are bent or broken). Find out at what point the power goes out.
To avoid future difficulties with the power connector, first insert the plug into the laptop and then the power cord into the outlet. On the contrary, it is not worth doing, since when the plug is connected, a spark will appear, spoiling the contacts.
If everything is in order with the power supply and connectors, and the laptop still does not turn on, then check the battery. Remove the battery and turn on the device without it. If this does not help, take the laptop to the service center.
DOES NOT boot from disk
This can be signaled by the inscriptions on the screen in English. For example, Error loading operating system or something SIMilar. First, disconnect all external devices (flash drives, disks, etc.). Then reboot. If it does not help, then it is either a software or a hardware problem Hard disk.
