HI my battery is constantly showing up at 100%. I've updated BIOS, enabled and disabled and deleted AC adaptor and battery in device manager. Device manager says that the devices are working properly. Windows troubeshooter doesn't find anything. I'm stumped as battery is new and charging fine. Old battery was replaced and said it was at 0% but was old and only lasting a few minutes once plugged out. Any help would be really appreciated.
