Chosen Solution
I’ve replaced the MagSafe charger, battery, and I/O board on my late 2010 11” MacBook Air but the thing is a paperweight. It won’t boot even when I bypass the battery. Does anyone have any recommendations for what else I could try? I haven’t spilled anything on it, or witnessed a surge of any kind. So I’m at a loss! Thank you in advance.
There’s nothing more than the logic board left unfortunately. Try disconnecting the keyboard not to leave anything untried, but if you still have the dim light a board replacement seems to be the only solution, as even a component level repair wouldn’t cost less, but rather the contrary.
