[QUOTE="pigoo3, post: 1615671, member: 56379"] As a repair person...you know that there's really not a whole lot of parts inside an Apple laptop computer. You've replaced a few things so far...and maybe there's a few more small things that can be swapped out to see if it helps. But eventually you end up with just one BIG part remaining...and that's the logic board. And this is one expensive part to replace if this is the problem. If you don't have any good logic boards to swap in (and this problem is the logic board)...then this computer just becomes a "parts computer"!;) I have two more ideas in case you haven't tried them yet: 1. Have you tried an SMC Reset? Although...a battery swap pretty much accomplishes this when it is done. 2. Does this model MacBook Air have a separate DC-In board (Magsafe board)? If so, you could try swapping it. - Nick [/QUOTE]
