Computer has been working fine until this. I left it plugged into my Apple Thunderbolt power cable over night. The next day it would not turn on. After looking at YouTube videos I played around with holding down the power button and randomly plugging in the MagSafe charger. It randomly turned on during this. Now it is completely dead. The green / orange light still comes on when I plug in the charger but this thing will not power on. I opened up the bottom case and tried unplugging and replugging the battery in with no luck. Honesty I just need this thing to turn on once so I can de-register Adobe Photoshop CS6 ... Any ideas ?
