I reset my PRAM last night due to some other issues I was having. The Magic Mouse battery was at about 80% or higher when I shut it down. I turned my laptop back on at 8pm tonight. I left it idle while downstairs and by 11pm it was down to 20%. 11:30pm down to 10%. Midnight, it died. What the hell could I have done? Should I reset the PRAM again? I'm at a complete loss!
