Hey, wondered if anyone had encountered this same problem as me... I have a 15" MacBook Pro that's about a year and a half old and no longer runs it's battery down to empty. The meter gets to about 1/4 full (not yet in the red) and then the laptop just turns off without warning. It doesn't shutdown properly or sleep - just instant off, losing anything I had open. Battery Health Monitor tells me it has 78% it's original capacity at 182 charge cycles. That seems kind of bad but I'm not sure it explains this problem. It feels like somehow the laptop is no longer correctly measuring the charge?? Does anyone have any ideas what's happened or if it's easily fixable? Thanks in advance!
