Just got a brand new laptop (Compaq Presario 700 series), Athlon 1.2ghz, 512mb ram, DVD/CDRW... except I got a little problem, or question that is. I've never owned a laptop before so I don't know how the battery charging works. If the laptop is plugged in, the battery does charge (it was at about 10% when I got it, and now it is at 53%). However, it has not gone passed 53% in the last 2 hours or so. Do I have to leave the laptop off and the AC adapter plugged in to get a better charge? Thank you for any responses on this issue.
