Dim green light on MagSafe after replacing battery and I/O board.
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.
