Last night I guess my plug was sideways so it only looked like it was plugged in. I know it came out and I thought I put in on correctly, guess I didn't. Anyway, this morning it was shut down and showed 0% charged. I think it was probably around 11 or 12 when it wasn't charging and I was at the computer again around 7:45 this morning. So I would guess it was aprox 8 hours that it wasn't plugged in. How long should it run on just the battery?
Thanks
