Recently my laptop randomly shuts off without warning despite the battery being at nearly 100%, maybe ninety six% or so (for some I can't type number nine here).9
Today, I discovered that the battery isn't charging. It's showing "0%, charging", but the power level does not increase. Is the battery busted? I replaced the battery maybe 2 years ago. I don't have an extra laptop or charger of the same model to test...
