Yesterday evening (1 AM) I powered off my laptop with Linux 7.1.rc2-1, with battery 65% Today I wanted to power on, but no reaction. I connected to AC and it took a while then it started. I checked battery, it was only 5 %. So it seems the battery drained completely over night. I’m pretty sure I really shutdown yesterday, no standby. So what happened? Battery issue? Kernel issue? Maybe the laptop restarted itself after shutdown? Fans spinning after shutdown? I remember a similar issue once...
