(SOLVED) Why Does My Laptop Keep Turning OFF?

Why does my laptop keep shutting off?

The main reason why your laptop keeps shutting off is because of dirty CPU fans, malware on your PC or a battery defect.


Possible Causes:

  • Fans not working
  • Malware in PC
  • Battery Defect


Fans Aren’t Working

Overheating is one of the most common causes of your computer or laptop shutting down unexpectedly.

Because the heat has nowhere to go, this is the bane of most computers, particularly laptops. To avoid this problem, ensure that the computer’s fans are in good working order.


This is such a common and critical issue that most computers now have a built-in mechanism that will shut down your computer if any of its components become too hot.

The most likely cause is a dirty or damaged fan. Pay close attention to the sound of the fans to see if any of them are making noise. If one is, the other is likely broken.


Malware in PC

Assuming your computer is powered on long enough, begin with a malware scan using your preferred software.

Consider booting from a live operating system disc to prevent malware from shutting down your computer before you can clean it.


Battery Defect

A defective battery will cause the laptop to shut down randomly in most circumstances. As a result, it is important to keep an eye on your battery while it is in use.

If the battery fails to last longer or the % drops quickly, it is possible that the battery is causing your laptop to shut down intermittently.


You may get a new battery, which should solve your problem. A faulty power line is another cause of battery problems.

The cable may not be charging your battery properly, or the connection may be loose somewhere. As a consequence, it is smart to look into such options.

How do I fix a laptop that keeps turning off

To fix a laptop that keeps turning off, you must check and clean the fans, remove the malware or replace your battery/charger.


Check/Clean the Fans

If your computer is sporadically shutting down, inspect your video card fan, case fans, and CPU fan, and thoroughly clean the components.

They can become clogged with dust, hair, and other nasty material, making it difficult for the computer to cool itself.

It would be best to inspect the laptop’s vents to ensure no obstructions, but this may not be easy to verify or clean on your own.

Another solution is to monitor the interior temperature and limit the heat generated.


Remove Malware

To guarantee your system maintains ideal performance and heat levels, you might strive to reduce high CPU utilization and resolve memory leak concerns.

Suppose you have this issue while using the laptop for gaming, video processing, or other intensive tasks. In that case, you may consider utilizing an external graphics card and a laptop cooling pad to minimize the temperature.

There might be malware causing it to shut down randomly.So, check your complete Windows system for viruses. Yes, it will take some time to accomplish, but it is well worth the effort.

  1. Fortunately, Windows Defender may identify it, but it’s also worthwhile to test alternative antivirus software.
  2. If malware is found, follow the instructions supplied by the antivirus application to remove it.
  3. Then restart your computer and test it.


Replace Battery/Charger

Most gadgets have specified charger ratings intended to be used with the device. Using a lower voltage or greater current adapter may cause your gadget to malfunction or shut off.

If your battery has given out, the only solution is to replace it; however, check to see if your charger may be the culprit.


Why does my laptop keep turning off when starting up?

The reason why your laptop keeps turning off when starting up could be because of a hardware failure.


Whether you’ve just added new hardware, now is the time to uninstall and see if the shutdown problem goes away.

To check for hardware issues, open the Device Manager and see if it indicates any errors.


If there is a hardware fault, the indicated hardware error would be an excellent place to start looking for a solution.

  1. A laptop switches off randomly owing to hardware difficulties, which might physically damage internal components.
  2. At such times, a thorough examination of all internal components is required to guarantee appropriate connections and hardware integrity.
  3. It isn’t easy to do so on your own for a laptop. Therefore we propose going to a service facility.


Why does my laptop shut down after a few seconds of turning it on?

The reason why your laptop shuts down after a few seconds of turning it on could be because you changed your BIOS settings.


Instead of hunting for the erroneous option, reset the BIOS to default. Because laptop BIOSes are intended to function with that specific laptop, you seldom need to change the settings.

Any configuration causes a hardware component to operate outside its factory default operating range.


While resetting the BIOS to factory settings is a useful starting step, it is insufficient. You’ll also need to reset any software that allows you to overclock or change hardware settings from the desktop.


If your computer is shutting down quicker than you can, try booting into Safe Mode.


If the BIOS is reset and the computer shuts down in Safe Mode, it’s a dead giveaway that the issue isn’t caused by overclocking or other faulty hardware settings.


Why does the laptop keep turning off after a few minutes?

The reason why your laptop keeps turning off after a few minutes is because you may have overclocked your RAM and your laptop is unable to keep up.


If you activate overclocking on your computer, it may become unstable when utilized for more intensive gaming or video processing tasks. This can be a difficult problem to verify. Your best approach would be to deactivate overclocking on your laptop or PC and see if it stops the machine from randomly shutting off instances.

Anything to do with overclocking, RAM timings, or voltages is one of the things we’re attempting to reset in the BIOS.


Why does the laptop keep turning off randomly?

The reason why your laptop keeps turning off randomly is because it may have incompatible or outdated drivers.


The issue with a hardware component frequently is not the device itself but the associated driver. Incompatible drivers can create a slew of issues.

A driver failure can always bring a computer to a halt. If you suspect a driver problem, I recommend reading our Windows device drivers guide to identify the malfunctioning driver and how to deal with it.


Laptop keeps turning off when plugged in

The reason why your laptop turns off when plugged in is because it may have an operating system error.


Your operating system is a sophisticated collection of software code; things can go wrong and force the computer to shut down.The most prevalent cause is system file corruption. Most operating systems provide a repair install capability to reinstall the operating system without losing your data.

However, you must consult the manual for that operating system. Look for a repair feature to scan and repair all system files for errors.

The System File Checker is the program you’re looking for in Windows.


Why is my laptop turning off when unplugged?

The reason why your laptop is turning off when unplugged is because its battery may be drained out.


Laptops rely on their batteries to work. They need to be charged and have sufficient power to stay on.
