CHECK your system for virus.

Hello, the major reason of laptop randomly shutdown is Overheating, you said it is not over heating...

I will suggest you couple of things that you can try:

1) remove the battery and plug the laptop on direct power supply, then place the laptop on a flat and hard surface and then boot the laptop.

or do a complete virusscan of the laptop.

or reinstall the OS...

Sounds like a possible virus.or a hardware conflict

Hello,
Check the computer for virus and spyware.
Thanks

BIOS setting for automatic power on?
