I'll go through our S.O.P. for the MacBook Air, and check off the ones that you already took care of.
- First try another power adapter. However, if you do indeed have a fully-charged battery, this isn't an issue and the computer still should be powering up.
- It is POSSIBLE that your battery is charged, but faulty (not likely, but possible). Does the sleep light flash 5 times, pause, flash 5 times, pause, etc? If so, the battery is unhappy. In that instance, try a different power adapter to circumvent the issue and see if the machine boots (it's possible that both your battery and adapter are bad. Again, not likely, but I'm postponing the next step as much as possible).
- If 1 and 2 don't work, you must replace your logic board. It's possible that a RAM issue is causing the problem, but it's soldered onto the logic board. That's the trade-off with making things small...many components gets centralized onto one part.
