Only had my MBP for 2 months - heres my first problem. Like it says, it doesn't charge when its turned on... the LED on the magsafe connector flashes green/off (not green/amber btw)... also, the screen turns off quickly... as if no power was connected and it's conserving power. If i turn it off, the magsafe LED goes amber and it charges ok... turn it back on... LED flashes w/ no charging. I cant find any info from apple about what the green/off flashing means. This is V.annoying and V.crap!... Any ideas?
