Hi, my X280 just suddenly won't turn on. It was left on a bed alone so no physical damage. When plugged in the charging indicator is solid white after flashing white 3 times. I've tried turning it on with the battery out but plugged in. I've also tried draining the CMOS battery (unplugged CMOS and the battery and held the power button down for 10 seconds before plugging everything back in.)

I'm wondering now if it could be a problem with the power button? The laptop is dual booting Fedora 38 and Windows 11 if that helps and wasn't powered off but went into sleep/hibernation before this behaviour. Is it somehow stuck in sleep mode? I have had some issues with sleep to wake being slow/finicky before.

I have access to a screwdriver set and isopropyl alcohol. What would my next steps be?

Try the pinhole reset, which is the same principle as this

Yeah I have done. I think the laptop has nuked itself somehow. Maybe the power button board.

Wow, What have you tried so far?
