After reinstalling windows on my laptop, my laptop battery appears to be stuck at 6%. I dont think its very realistic, because i can still run it on battery for ages after i unplug it and no matter how much i charge it, the level wont go over 6%. Is there a way to reset the battery level?
Try downloading a program like BatteryCare and see if that gives you a proper reading.
EDIT: I would also try performing a full discharge. The procedure is explained in the "Guide" tab of the BatteryCare website which is linked above.
