My Acer Swift SF314-57G laptop is running windows 10 Home 20H2. It
regularly won't shut down (via start -> Power -> Shutdown) or go
to sleep (either via Start -> Power -> Sleep or by shutting the
lid, which is set to put the computer to Hibernate in the power
settings). Instead of shutting down/going to sleep, the screen goes
black but the fan stays on. In this state, it's also not possible to
reawaken the computer. It remains stuck in this half on/half off state
unable to either sleep/shut down or start up again. This can last for
hours until either a) the battery runs out or b) I long press on the
power button or c) I use a pin to press the reset button. Any work that
was open is also lost in this state. How can I fix this problem?
