Laptop Won’t Start What To Do

Table of Contents

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 indicates 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.

Laptop does not turn on. replace the video 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 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-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 a graphics 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 video card, 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.

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 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 see only a black screen, it is very likely that you will need to replace the video 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 basic 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.

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 the wrong 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.

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 the 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, 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 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 a graphics 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 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: incorrect connection of a defective device via USB, processor overheating, short circuit, and others.

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 HP pavilion / compaq / probook, asus, acer aspire, Lenovo yoga, Samsung, dell inspiron, MSI, good, sony vaio, packard bell, dns, emachines laptops. 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 may also sometimes NOT turn on. What to do if the laptop does not turn on. just a black screen 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, MSI 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 what to do if the laptop does not turn on. only a black screen, I have collected the most common causes and remedies.

Laptop won’t turn on. problem solution!

Worked your laptop for a year or two and stopped turning on? Or maybe he didn’t work at all. Well, such a nuisance happens, and in this article I will tell you what you can do in this situation yourself, and when you need to contact the specialists at the service center.

All problems with a laptop can be divided into two parts: hardware and software. Hardware 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.

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 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 plug 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 at the moment of connecting the plug, 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 yourself without disassembling the laptop, if it really does NOT show signs of life at all or shows a black screen. serious reasons may include a non-working motherboard, a broken internal power controller, a south / north bridge, broken contacts inside the device, failed BIOS firmware, and others.

Constantly reboots or shuts down

The laptop can reboot indefinitely before attempting to boot Windows. This is a serious hardware problem, the south bridge may overheat, usually due to a short circuit in it. Most often this happens due to a breakdown via USB (remember what you inserted into the USB connectors).

Or processor overheating due to a dust clogged cooler or a loose heatsink. But this is rare and is mainly accompanied by high fan speeds. In this case, the laptop may turn off or reboot at different times.

In the absence or poor power supply, the following picture can be observed: the device turns on, but quickly goes out due to a dead battery.

Turns on, shows a splash screen or writes something and hangs

It may be that the initial splash screen appears or information is displayed, but then the laptop does not start, it also beeps or writes about errors. The probable cause is problems with BIOS settings. You just need to enter BIOS and reset all settings to 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 download 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 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.

Windows starts to load, but everything is bad.

It’s a kind of option that, as usual, Windows starts loading, but then the laptop reboots itself, errors appear on a black or blue screen. Here again, there may be a problem in the hardware, ie. Hardware failures, and maybe software.

The surest way to test, again, is to reinstall Windows. “Lite” check option. will run from a bootable USB flash drive with Windows. If the laptop with it behaves similarly badly, then the case is probably rubbish, you need to carry it for repair. In general, Windows boot problems are a completely different story.

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.

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 the “FnF2” buttons.

The screen may really not work, and there are also various artifacts instead of an image. The surest way to check if 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 video 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, dustiness / pollution thereof, or improper use of your “friend”, video cards overheat and break down faster. This is especially true for nVidia video cards (GeForce 8400M, 8600M, 9300M and others).

No need to play with the computer on your knees, on your stomach, or in any position that blocks the vents. It is advisable to use laptop cooling pads. And in general, if a laptop is not positioned by 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 your graphics card temperature.

So, if the matter is in the video card, then try to pull it out, if the design allows, or turn it off using the switch, which is present on some models. The beech can work without a discrete graphics card, it just won’t work 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).

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 video card or other laptop chipsets 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.

“The computer did not start correctly” or “Windows does not seem to boot correctly

The first common variant of the problem is when Windows 10 does not start, but instead first (but not always) reports an error (CRITICAL_PROCESS_DIED, for example), and then a blue screen with the text “The computer has not started correctly” and two options for actions. restarting the computer or additional parameters.

Most often (with the exception of some cases, in particular, INACCESSIBLE_BOOT_DEVICE errors), this is caused by damage to system files due to their removal, installation and removal of programs (often. antiviruses), the use of programs to clean the computer and the registry.

READ  USB ports not working on laptop

You can try to solve such problems by repairing corrupted files and the Windows 10 registry. Detailed instructions: The computer does not start correctly in Windows 10.

Windows 10 does NOT start

Questions about what to do if Windows 10 does not start, constantly reboots, a blue or black screen at startup, reports that the computer does not start correctly, Boot Failure errors are among the most frequently asked by users. This article contains the most common errors that prevent your Windows 10 computer from starting and how to solve the problem.

When fixing such errors, it is always useful to remember what happened to the computer or laptop just before that: Windows 10 stopped starting after updating or installing antivirus, perhaps after updating drivers, BIOS or adding devices, or after an improper shutdown, a dead laptop battery, etc. P. All this can help to correctly identify the cause of the problem and fix it.

Attention: the actions described in Some instructions may lead not only to fix Windows 10 startup errors, but in some cases, to the fact that they will get worse. Only take the described steps if you are ready to do so.

The Windows 10 logo appears and the computer shuts down

The reasons for the problem when Windows 10 does not start, and the computer turns off itself, sometimes after several reboots and the appearance of the OS logo, is similar to the first description of the case and usually occurs after an unsuccessful automatic startup fix.

Unfortunately, in this situation, we cannot get into the Windows 10 recovery environment available on the hard drive, and then we need either a recovery disc or a bootable USB flash drive (or disk) with Windows 10, which will have to be done on some other computer (if you do not have such a drive).

For details on how to boot into the recovery environment using an installation disc or a USB flash drive, see the Windows 10 Recovery Disc guide. After booting into the recovery environment, we try the methods from the section on “The computer does not start correctly”.


There are several options for the causes of the error on the Windows 10 INACCESSIBLE_BOOT_DEVICE blue screen. Sometimes it’s just a bug when updating or resetting the system, sometimes it is a consequence of changing the structure of partitions on the hard drive. Less commonly, physical problems with the hard drive.

If in your situation Windows 10 does not start with this particular error, You will find detailed steps to fix it, starting with the simple ones and ending with more complex ones, in the material: How to fix the INACCESSIBLE_BOOT_DEVICE error in Windows 10.

Boot Failure and An operating system was not found errors

Another common variant of the problem with starting Windows 10 is a black screen with the Boot failure error text. Reboot and Select Proper Boot device or insert boot media in selected boot device or An operating system was not found. Try disconnecting any drives that do not contain an operating system. Press CtrlAltDel to restart.

In both cases, if this is NOT the wrong order of the boot devices in the BIOS or UEFI, and NOT a damaged hard disk or SSD, it is almost always the Corrupted Windows 10 boot loader that is the cause of the startup error. Steps to help fix this error are described in the instructions: Boot Failure and An operating system was not found on Windows 10.

Black screen when starting Windows 10

The problem when Windows 10 won’t start and instead of the desktop you see a black screen has several options:

  • When, judging by everything (for example, by the OS welcome sound), in reality everything starts, but you only see a black screen. In this case, Use the instruction Windows 10 Black Screen.
  • When, after some action with disks (with partitions on it) or an incorrect shutdown, you first see the system logo, and then immediately a black screen and nothing else happens. As a rule, the reasons for this are the same as in the case of INACCESSIBLE_BOOT_DEVICE, try using the methods from there (the instructions indicated above).
  • Black screen, but there is a mouse pointer. try the methods from the article Desktop does NOT load.
  • If after turning on, neither the Windows 10 logo nor even the BIOS screen or the manufacturer’s logo appears, especially if before that you already had problems starting the computer the first time, the following two instructions will be useful to you: The computer does not turn on, and the monitor does not turn on. I wrote them quite a long time ago, but in general they are still relevant now and will help you figure out exactly what the matter is (and it is most likely not in Windows).

So far, this is all that I managed to organize from the Most common problems for users with the launch of Windows 10 at the current time. Additionally, I recommend Pay attention to the article Restoring Windows 10. perhaps it can also help with solving the described problems.

New laptop. the unit does not want to charge

Assembly-only devices have a pre-installed licensing system. In this case, the battery of a brand new laptop does not charge for 2 reasons: a factory defect or incorrect battery initialization.

You can help the device like this:

  • Turn it off;
  • Disconnect the gadget from charging;
  • Take out the battery;
  • Hold the ON key (20 sec)
  • Return the battery to its place;
  • Connect charging.

The only thing left to do is to turn on the device and make sure it works correctly.

A couple more tips for those who have a removable battery. For example, an elementary method:

  • Disable charging completely;
  • Remove the battery from its compartment;
  • Press and hold the power key for 1 minute.

Then you need to sequentially perform the steps: return the battery. turn on the charger. wait 15 minutes and turn on the device. Everything.

New variation of the previous method:

  • Disconnect charging with the device switched on, DO NOT touch the battery.
  • Press and hold the power key to turn off the device.
  • Connect the power supply.
  • Wait a quarter of an hour.

The procedure ends with turning on the device. Thus, you can cope with the problem yourself, without involving a master. 3 more common problems and their elimination are discussed below.

Battery connected. charge available

The age of the device and its manufacturer do NOT play any role here. Laptops from Samsung, Xiaomi, Prestige or other companies are equally affected by this problem.

The defect is identified as follows. in the notification area next to the icon indicating the charge, a message is displayed with the text: “connected, not charging”. Windows users (version 10) will read a slightly different message: “Charging not in progress”.

The first cause of the problem is software anomalies that only a specialist can figure out. What can you do yourself? The universal method is to “reset” the BIOS.

This is done in 10 steps:

  • Turn off the device completely.
  • Take out the battery.
  • Disconnect the gadget from the network.
  • Hold the power key on (1 min).
  • Connect the device to the mains (without battery).
  • Press the power key and go to BIOS.
  • Reset to factory defaults (EXIT menu. Load Defaults).
  • Save changes and turn off the gadget.
  • Disconnect the power supply cord from the laptop.
  • Return the battery to its place, connect the charger.

At the end, it remains to turn on the device (user settings will be saved) and observe its operation. If everything is done correctly, then “Windows” will please the user with a message: “connected, charging.” In case of failure, it is worth studying the following sections of this material and apply other methods of eliminating breakdowns.

Battery charge does not reach 100%

Most of the manufacturers of laptops develop and install specialized software on devices to monitor and control the consumption / condition of the battery. Most often, these “optimizers” are the culprit for incomplete charging.

In such utilities there are 2 modes of battery operation, the first of them saves energy and does not allow you to fully charge. Switching to the second mode will restore 100% charge. A radical solution is to disable or completely eliminate the utility.

If the last procedure did not help, then the matter may be in the natural wear and tear of chemical elements, failure of controllers, oxidation of contacts. In this case, it will not cope with the problem on its own.

Overheating of the battery. causes, effects, solutions

The problem arises if the owner of the gadget did not keep the cooling system clean. As a result, the dust accumulates in a dense layer and the battery, along with the entire device, simply overheats. Also, this defect can occur if you use the device in stuffy / dusty rooms. In hot seasons. this is one of the first reasons on the list why laptop battery won’t charge.

How to tell if a battery is overheated? When the device is turned on, it charges quite normally for a certain period of time, and then the message “the unit is not charging” appears. This is a sure signal of its overheating. What are the solutions? First of all, it is necessary to clean the device from dust accumulations. To do this, you should contact a laptop technician.

In addition, special laptop stands will save the battery from overheating. They help to cool the device as a whole, and therefore, extend the life of the gadget.

An important tip in the end: The laptop should not be placed on soft surfaces (such as beds or sofas) so as not to block the ventilation holes.

Laptop won’t charge: 5 main reasons and more than 10 solutions

What is the reason that the laptop suddenly stopped charging? Can this be fixed without calling a repairman? This article discusses the 5 most common charging problems that users encounter, as well as ways to fix them on their own.

Does the laptop NOT charge? The software is to blame!

The creators of the devices often stuff devices with various utilities. Their purpose is to increase the performance and lifespan of devices. The flip side of the coin is that the battery charge does NOT reach 100% because of this. The same goes for the official software where the error has crept in. You can fight this by finding and eliminating unnecessary software.

Finding harmful utilities is easy:

  • Name “Start”. “Control Panel”;
  • Go to “Programs and Features”;
  • Select Unnecessary software (hint: it is easy to recognize a software pest. its name contains the brand of the laptop)
  • Select it with the mouse button and click “Delete”.

Securing success is worth rebooting the gadget.

In the end, all of the above methods are effective in 90% of cases of troubles in charging a laptop. Even beginners can use these instructions to help the gadget get back to work. If, despite all efforts, the charging is NOT working out, then the problem lies in the equipment itself: wear of the charger, lack of power, problems with connectors on the laptop, and more. In this case, only a wizard will be able to find out why a Lenovo, ASUS, HP or second-brand laptop is not charging.

Battery replacement (if necessary)

If wear is high, then it is probably a prerequisite for reduced battery life. To solve the problem, you need a new battery, in most models it is removable. In this case, you can change it yourself. In a number of modern compact models, the unit is not removable and its independent replacement will be more difficult. It is safer to do this in a service center.

What to do if the laptop battery does not charge?

When there are problems with charging, many people wonder. “why the laptop is plugged in but not charging?” and rush to replace it with a new one. Yes, the battery is a consumable item. It is designed for a limited number of charge / discharge cycles, and over time, the capacity becomes significantly less than the nominal value indicated by the manufacturer. However, the charging problem will not necessarily be solved by replacing it. In this article, we will look at the three most common problems and tell you what to do to solve them.

Problem: The battery on the laptop stopped charging

It happens that a device that used to charge normally stopped doing it at some point. The laptop is working and the battery is connected correctly, but not charging. This is confirmed by the absence of an inscription when you hover the mouse over the battery status icon in the tray. There are three ways to solve the problem.

Method 1. reset battery settings in BIOS

  • Disconnect power. Unplug the power supply plug from the device or unplug it from the power outlet.
  • Take out the battery. In models with a removable battery, and there are most of them, for this, it is enough just to turn the device over and move one or two locking devices that hold it.
  • Press the power button and hold it in this state for about a minute.
  • Insert the plug of the power supply into the laptop and connect it to the mains. In this case, it is not necessary to install the battery in place yet.
  • Turn on the laptop and enter its BIOS. To do this, at startup, press the key or their combination indicated in your user manual. Typical solutions: Del, F12 or F2.
  • Reset settings to preset value, Restore Defauts, and save BIOS settings, Save and Exit.
  • Turn off the laptop by holding the power button for 5-7 seconds.
  • Turn off the power supply again and Reinstall the battery.
  • Insert the charging plug and plug the power supply into an outlet.
  • We turn on the laptop in the usual way.

If the method worked, then we should see the system message, bring the mouse to the tray icon: the battery is connected and charging.

Method 2. removal “useful” utilities

In some models, manufacturers install “useful” utilities that monitor the state of charge. In particular, they can implement a mode that ensures the maximum battery life. It may prevent the battery from being fully charged.

Try looking for such a program in the system tray. If the battery icon differs from the usual system icon, then it is likely that some similar utility is installed on your laptop. Modern operating systems are quite capable of independently determining the optimal mode of using the battery and charging it. So it’s best NOT to install any third-party apps.

Diagnostics of programs on a laptop

If the diagnostic utility shows no significant wear on the battery in step 1, then the battery is probably NOT a direct cause of a drop in battery life. The culprit for the fast discharge may be some recently installed program that runs in the background and does NOT allow the processor and Wi-Fi chip to go into economic mode.

Open the Task Manager by pressing CtrlShiftEsc and Analyze the CPU usage of background programs. Sort apps in the list by CPU usage and watch for a while. Removing unnecessary programs running in the background will increase battery life.

What to do if a new battery won’t charge

A much more difficult situation is when only the installed new battery on the laptop does NOT charge at all. To get started, we advise you to do the BIOS reset operation described above.

Method 3. if the power supply does not work

Another prerequisite may be the loss of performance of the power supply and a decrease in the reliability of its plug. In this case, the battery has nothing to do with it. It’s easy to check.

  • Turn off the laptop, Unplug the power supply from the socket.
  • Take out the battery, insert the plug of the power supply.
  • Plug the power supply into a power outlet.
  • Press the power button.

If after that the laptop does not work, then the power supply or its cord is out of order. Also, an old power supply may NOT provide sufficient current to operate the laptop and charge its battery at the same time. Such a device must be replaced.

What to do if the laptop does not turn on: 6 main situations and ways out of them

No one is safe from laptop breakage. But the good news is that most of the problems that arise in the operation of this device can be solved. It is only necessary to determine the cause of the breakdown and its nature, and then act according to the situation. All laptop problems are either software or hardware. It is necessary to accurately diagnose the malfunction, and then you will already know exactly what steps to take to eliminate it.

So, why the laptop won’t turn on and what to do?

A message is displayed about the impossibility of starting 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.

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 does NOT boot. 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 “does not start at all”” notebook. And sometimes it still starts, 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 appears about errors 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 must 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 can hear the engine trying 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 each. 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.

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 up, but its screen remains dark. What to do in this case?

Take a close look at the monitor. Perhaps you still manage to consider something? If so, then the screen, most likely, is 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 video card. This element sometimes overheats and breaks down. By the way, some video cards are prone to breakdowns more often than others. For example, nVidia graphics cards have a short lifespan.

To prevent such damage, do not hold the laptop in 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 more. do not forget Monitor the temperature of the video 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 video 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.

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 caused by a 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.

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.

Thus, if the laptop does not turn on, then it still does not lead to panic. In many situations, you can diagnose and fix the problem yourself. You just need to analyze your recent actions with this device. For example, if you spent many hours playing a game shortly before the breakdown, then your video card is most likely overheated. Try a little and you will be able to bring your device back to life again.
