Had the laptop shut off on me while at near 45% battery. the charging light and everything would not light up and the chromebook would not power on. I took the chromebook apart, took the battery off for about 30 minutes. Reinstalled thinking I'll replace the motherboard. Just for giggles I plugged it back in, and the lights came back on.

Also when I hit the power button everything powered up just as before. Still at 45%. So I'm guessing by removing the battery I cleared up what ever power issue was keeping everything powered down. Time to backup the offline and downloads folder. ;)
