I have similar problem as this one.
Things I tried
- disabled "Allow device to wake up my computer" in device manager
- after wake, I tried to run
powercfg -devicequery wake_armed, which just output one blank line. - after wake, I tried to run
powercfg -lastwakeand the weird thing is that it says that power button woke it up, which looks impossible. (And hibernation works perfectly) - restarting my notebook and trying to enter sleep mode BEFORE actually logging in
powercfg /requestsgives me
DISPLAY: None. SYSTEM: None. AWAYMODE: None.
- reset default power plan settings
this all started to happen after small amount of juice fell into keyboard. I immediately unplugged it, shut downed my notebook. Because keyboard was sealed and some keys didn't work (they were probably wet), I put it into water for a day and then kept it 2 days on radiator. After that, everything worked fine, except the sleep.
