The title sums it up. I have a new computer that starting yesterday will not charge the battery. I have not experienced any problems with the battery or power systems before this.
*original title - (Plugged in, not charging) with 21% charged battery. It has been this way for 24 hours after many reboots. This is a 2 month old acer aspire 5740-6378. Is there a way to reset the power control software? Until now it has performed very well.*
