This is such a common issue because most computers now have a built-in mechanism that will shut off your computer if any components become too hot.

For a laptop shuts down randomly,

You’ll want to look at your graphic card fan, case fans, and processor fan and take a proper time to clean the components.

They can be covered with dust & dirt that makes it hard for the computer to cool itself.

You’ll also need to check out the vents for the laptop and make sure that there is proper ventilation available.

Note:- Do not put your laptop on a blanket or pillow. Instead, you should put on a table or where good ventilation available.

Another most common reason for a random shutdown of your computer is a hardware components failure.

  • If the power of the adapter doesn’t match, it causes damage to your laptop. Which directly impacts your battery, and in the worse scenario, it was a damaged motherboard.

  •  It’s recommended to buy the same rating AC and DC power adapter. Also, compare the output and input power of the new adapter compare it with your old adapter.
