I suspect your power control IC located on the back side of your main logic board has some corrosion or is bad. Look at Step 15 [guide|3745|of the system teardown|page=2] locate the TPS 51982 Chip. Are you able to solder SMT components? If not you'll need a new logic board or will need to find someone with the correct tools and skills to replace this chip if it is bad.
