@llamee see my recommendation on the other thread to get yourself a new battery.  Be sure it is OEM and not counterfeit.

To everyone else, I know this isn't scientific, but normally I'd have lost at least 5-7+% in the last 90 minutes.  However, after an hour I looked at my battery and it still said 100%!  Right now it's at 98% after 90 minutes.  According to the battery meter I can get through the rest of today, and all of tomorrow without a charge.
