Hi guys, I'm new here, and I'm having some problems with my MBP... Recently, it started randomly shutting down with no warning.. it's not like quitting all apps, but really sudden complete loss of battery... The computer doesn't restart when I press the power button, nor does the battery light show anything when I press the check-battery button (although there has always been at least 30% charge left in the battery). It then works fine again when I plug in my power cable, and the battery light flashes again, at the % of battery it was at... Sometimes the time resets itself to 2000 as well... It's a 2009 13 inch 2.26 core 2 duo, running mountain lion 10.8.2 with 4GB memory.. Edit: Oh right it has been saying service battery ever since I upgraded to lion.. PLEASE HELP!!
