[AC Question]

Nexus seven powered down with 2% power left. Next time I try to power up plugged in, the machine would not charge.
I've tried various combinations of a button pressing but nothing acts as advertised.

Hi

be sure you are using the Original Charger for your device.

1. At 2%, the battery probably has to be precharged. If the stock charger doesn't do precharge (most of them don't), the battery has to come out and be connected to a charger that does precharge.

2. You should never drop a lithium battery below 40%. Only high-discharge lithium batteries are made to take that kind of use. (And you won't find any in cellphones - they cost more for the battery than a flagship cellphone costs.)
