PC switching itself on overnight

[Jackimus]

'Shutting down' on Windows 10 doesn't actually shut down, even if you hit the physical power button, meaning any policies or timers left over from it being a work machine will still fire and boot it up.

Quick way to get around this rather than hunting for what is causing it might be to shut down through Powershell/command prompt by typing 'shutdown /s /t 0' without the quotes. This is an actual shutdown Vs the deep hibernation of other methods.

I just pull the power cable out the back - it's not turned on once since

K.I.S.S. usually works ,or did until it didn't.

are you having power cuts?
ours boots up even if the power flashed off and back on,

That can be disabled in BIOS.
Power off - reboot/ do nothing on power restore.
In hibernate, mine would occasionally re-start during the night until I realised it was being polled by the PC in the back room which is always on.
I now flick the power switch off at the wall.

That sounds like authentic PC behaviour. A bit like a house that’s been bodged and extended for decades - trying to find things that should be together, but hidden down different corridors and false attics.

Anyway, it stayed off overnight, so I think the BIOS settings did it. Cheers
