Acer E 11 battery failure

[frcguy]

We use an Acer E 11 laptop (came in the Rookie KOP last year) for our driver station laptop. After pulling it out of storage this week (we left it unplugged and in storage since around the conclusion of the Championship, I know - not a great idea) the battery will no longer charge. We've left it plugged in for multiple hours, power cycled, etc. to no avail. We've got an event this weekend (Capital City Classic), and thus need the laptop to have a functional battery. If I can't get it working, we can probably throw something together for the event but I'd prefer not to as the E 11 already has everything set up. Any ideas? Thanks in advance
