Most Common Reasons Why Your Laptop Is Randomly Shutting Down.

1. Dirty Fan/Overheating

The first thing to do when you notice that your laptop shuts down randomly is to check for overheating. Now the question is

What causes overheating in laptops or computer?

The first culprit is probably that the fan is not working or is faulty.

Laptops of nowadays are have a built-in mechanism that will shut off your computer if any of the components become too hot. This is a protective mechanism protecting your expensive electronic device.

Most times you may hear an abnormal noise coming from your computer, such as a high squealing sound, this could be an indication of a fan malfunction.

For you to access your laptop fan, you need to open your laptop casing. Mostly the fan is by the left of the power input side

If you find that the fan in the power supply is not working correctly or at all, and the power supply is very hot to the touch, you may need to replace the power supply.

An overheating power supply, due to a malfunctioning fan or dirty fan, can cause a computer to shut off unexpectedly. Continuing to use the faulty power supply can result in damage to the computer and should be replaced immediately.

Note If your issues are on a laptop, I do not suggest you opening the computer. Instead, verify the fan from the side of the laptop to see if it is working and blowing out hot air. Also, you may get a cooler pad to use with the laptop to help lower its running temperature.

Tip

Working on the interior of your machine provides an opportune time to clean the inside. Dust, dirt, hair, and other trapped debris can prevent proper air flow, which may lead to overheating.

When a laptop shuts down abruptly, it can also be caused by hardware failure. When there is a hardware failure, this can make your laptop to unexpectedly shut down.

The hardware to check first are as follows: RAM, CPU, your motherboard, power supply and your video card.

Also, you may have installed a new hardware that may be causing this problem. If you have recently added any new hardware, remove it from the computer to make sure it is not the cause of the problem.

In a situation that you did not add any hardware of such to your laptop, the best thing to do is to remove certain hardware like modem, sound card, vcard and some other non essential hardware that do not affect the operation of the laptop.
