That sounds plausible, though I thought any power running through it would've caused it to burn out. I was actually going to do a full disassembly with a mate

That sounds plausible, though I thought any power running through it would've caused it to burn out. I was actually going to do a full disassembly with a mate of mine who was an EE, but never got round to it. We attempted to do it with my iPhone (which was dunked into a toilet in an unrelated incident), but even cleaning everything with isopropyl alcohol it wouldn't work. I didn't hold high hopes for the MacBook. And no, water damage wasn't covered by warranty, but it was out of warranty anyhow. I just didn't want to pay another $2K for a MacBook Air (maxed out specs at the time).
