I hate troubleshooting hardware. Got a new battery for my linux laptop and it will randomly shutdown after 30 seconds to five minutes of being unplugged. This is how I find out that linux is dogshit at managing battery power.
I've narrowed the problem down to two things, linux miscalculating the current charge because it hasn't gone through a full cycle yet or having a usb mouse plugged in is too much for it.
According to Linux, a full charge gives me somewhere between 1 hour and 11 hours of use.
It also just powered off while I typed this, so both of my previous guesses were wrong. And because of the way it just turns off, it doesn't generate a crash report or a log line. Or if it does, I have no idea where.
