Hi Husler,

We need more details such as what operating system are you using and does anything appear on the screen at all before it shuts down?

Well try the following :

  • Inspect the battery. Turn off your laptop completely and shut down the flap.
  • Check for overheating.
  • Check the RAM and hard drive.
  • Check the power supply outlet and charger.
  • Perform a hard reset.
  • Run a malware scan.
  • Update the drivers.
