who ever gave this guy a processor might have well sold it themselves.

Hi /tech/
Im not sure if i am on the tight board, but might as well giv it a try...
So I bought a Macbook Air 2012 with liquid damage. It still powers on, but the battery is not detected and the laptop is horribly lagging.
On some forum, people say to take the motherboard and clean it with alcool. Is there anyone here who trid doing this? I think its worth a try, anyway. I can't resell this and if I can't repair it cheap I will just sell parts.
