I need some help! My 2008 MacBook Pro was working fine and I shut it down one day, and now it wont turn back on. I've tried a few of the Apple support tricks but they haven't worked. Now one weird thing is happening and I don't know what it means. When I attach the magnetic charger to the computer, the light goes from green to orange then right back to green. This computer has been off for a while so I know now that the battery has to be dead. Therefore, the charging light should not be green. I've tried a couple different batteries with the same result. Anyone have any idea what this means or how to get it to turn back on???
