Question

I am experiencing a very weird problem with my 2010 battery. It seems to charge fully to 100% (according to the power meter in control settings), and after a bit over an hour, the computer shuts off all of a sudden. I then re-plug and check the power meter and it is at 86%. I can recharge the battery and start over again, but it will not last more than this.
