I have a dell chromebook 3100 2in1 with a celeron N4000. when plugged in the battery instantly goes to 100% but still charges when unplugged it shows the correct percentage. like (85% KDE takes this a step further and thinks the computer is plugged in even when its not.
okay more info, I have tried another battery and that fixed the issue, but I put that battery the one with the issue, into the computer I took the battery from and now it refuses to boot with either battery. it just boot loops. no battery, it boots fine? wtf?
