What to do if your Laptop turns off randomly

Why is my Laptop randomly turning off?

When a laptop starts to randomly turn off, it can be very annoying and time-consuming. There are many reasons why this may occur and in some instances, you may be able to solve the problem yourself.

Failed Motherboard

If your motherboard has failed you either need to call a reputable computer repairs business or consider the purchase of a new laptop.

Faulty Fan

If your fan has died, it can be quite inexpensive to have a computer repair company install a new one for you.

Power Adaptor

An AC power adaptor may cause your machine to turn off if it senses an overload of power drain. The power adaptor may also be faulty. If the problem does not occur when you are using the battery or another power adaptor, then this will be the cause and you will need to purchase a new power adaptor.

Memory Failure

It is quite possible that you could have memory failure caused by your laptop turning off and on. You will need to reset the memory modules to ensure that the connection is good. It might be an idea to remove the memory modules one at a time and then test the laptop with each module to determine where the problem is as you may need to replace one or more of the modules.


A virus on your laptop may be the cause of the machine intermittently turning off. You need to ensure that your antivirus software is up to date then run a full scan and remove any malware that might be on the system.

Overheating Processor

An accumulation of dust and participles on your machine can cause problems with your fan which can lead to overheating of the processor which in turn leads to your machine randomly turning off and on.  In this instance, you need to clean all the dust etc off your machines internal working – or call a repair company to do this for you.

Poor Cooling

With an older laptop, it may just be that it is too hot. Try using the machine in an air-conditioned room and see if this resolves the issue.
