I have this Acer Chromebook 13 that after sitting for 6 months would die if you unplugged it so I bought an identical battery and replaced it. That fixed for a few weeks. Then the same problem again. I assumed this meant the battery shipped with a charge and when it died the charger wouldn't charge it. So I bought a charger. But it still won't run when not plugged in. Crosh shows no battery found. I know the battery is good and the charger is good. What the hell would be the problem. I called Acer they said it's out of warranty call a third party they said take it to best buy.  Anyone have any idea what this is?
