Here are some points which you can check and get the laptop shutdown issue resolved easily.

Another major cause of this problem is of cooling hardware or the dust problem. Most of the laptop after a long usage carry this major problem. In this, the laptops become extremely hot and the fan throws extremely hot air.
How to fix: You can fix this problem by a cooling paste that is applied on the processor. Note, do not apply it by yourself, and fix this problem by laptop repairing shops. Or you can also check your fan if it is working well, or you can also buy a cooling pad.

Battery problem is another major reason for random shutdown of laptop. This problem usually occurs after a long use age of laptops, or excessive charging. If your laptop shuts down randomly, test your battery if it’s working well or not. If it isn’t, you really need to buy a new battery. Make sure the battery has the same amperes the laptop requires, otherwise your laptop might have problems while working.

Hardware failure

This isn’t a common problem, but when it occurs, you cannot resolve this problem by yourself. If you are sure that all the parts of your laptop are working well, but the laptop just turned off, you should go and have your laptop checked by the service centers. Make sure the service center has enough expertise to check and repair your laptop. Because, most of the people do not have enough laptop hardware repairing expertise.

If you still have the virus problem in your computer, you need to go and have your laptop checked by the service center.

Most of the laptops either stop working or just turn off randomly because of ram crashing problem. This problem generally occurs when your ram stops working or by the displacement of your ram. To resolve this problem, unplug your ram, cool and clean it out and plug it again. Check if the problem is solved or not. If it doesn’t go and have your laptop checked by the service center.

There is another major cause for the laptops to turn off randomly that is the faulty power supply. It is the most dangerous problem as it can cause severe problems to your laptop like your laptop can go dead due to the faulty power supply. Because the value of current decrease and also increases, so it greatly damages the battery and laptop itself. If you are having the same problem, it is recommended for you to change your power supply as soon as possible. If you are not sure if it’s the problem of power supply, you can also test it, whether it’s working well or not!

No laptop service

The most common problems are overheating, random shut down and slow processing. Therefore, it is mandatory to service your laptop regularly from dust for a smooth and fast processing.
