Laptop turns itself off

Laptop turns itself off with a fairly full battery(today 85%) does not do this when plugged into mains

@Alison04 Does the laptop turn off suddenly with its lights off as well? or do the lights remain on and only the screen blacks out?

Also, do you know if any updates were recently installed or interrupted during an update?
