6 Reasons Why Your Laptop Keeps Turning Itself Off

Having your laptop turn off while being used is a real bother as you risk losing valuable data. If your laptop keeps shutting down on its own, it could be due to any one of the following reasons.

1. Overheating

If you often use the laptop on the bed with the laptop resting on a blanket, or on a cushion on your lap, you run the risk of your laptop overheating. If the laptop cooling fans appear to be running faster than normal or the chassis feels warmer than usual, your laptop is overheating. Laptops have heat sensors, which on sensing a rise in internal temperature will shut down the laptop. Thoroughly cleaning the laptop air vents to clear any dust can help rectify the overheating. Also, ensure that you place the laptop in a manner that allows for adequate air ventilation. In some instances the heating could also be due to a broken cooling fan. However, if the problem of overheating has been going on for some time, it may have already damaged the motherboard, and you may need to replace it.

2. Inadequate power supply

A defective power supply unit (PSU) is one of the most common reasons for laptops to turn off by themselves. A fault in the PSU will mean that your laptop is not getting enough power for the hardware to work properly. You may need to replace the PSU.

3. Computer virus

It is possible that your laptop is infected with a virus that is causing it to shut down on its own. Ensure that your anti-virus software is up-to-date. Also scan your laptop for any malware.

4. Faulty RAM

This can cause your laptop to shut down, crash or reboot by itself. Run a Memtest86 v4.0 to check if there is a problem with your laptop’s RAM. If the test confirms faulty RAM, then you will need to have it replaced.

5. Other hardware problems

Any faulty hardware in your laptop could cause it to turn off unexpectedly. Remove any recently added hardware to ensure that it is not causing the problem. If you have not added any new hardware, turn on your laptop with only the essential hardware (remove the modem, sound card and any other expansion cards). Running your laptop without these cards will help confirm if they are causing the problem.

6. Issue with the operating system

Your laptop may be experiencing a Microsoft Windows operating system issue. Re-install Windows to see if it resolves the problem.
