Why my computer shutdown by self suddenly?

Hi @alhalafi ,

Was the laptop hot when it shutdown?

Was the fan operating OK and is the fan vent clear so that the laptop doesn’t overheat.

If not then maybe it shutdown to protect the CPU because it was overheating.

If the fan is not working then here’s the hardware maintenance manual for the laptop. Go to p.42 to view the necessary pre-requisite steps and then the procedure to remove the fan and heat sink assembly.

If the fan is working OK and the vent is clear does the laptop work OK when the charger is connected?

If so then create a Win 10 battery report and check the Design Capacity value versus the Full Charge capacity to see what the status of the battery is.

If the battery appears to be failing it may need to be replaced, (see p.36 of the manual)
