Hi guys,
I have an 820-3462 that has been liquid damaged.
Initially it was DOA.
R6920 looked burnt so I replaced it and it burnt out again.
Made me look further along. R5081 and R4902 were shorted so I replaced these.
It now turns on and gives a picture but fans are on full and no green light. I think the PCH is getting hot but am not sure what the usual operating temp for this is. I don't fix many newer MBPs.
I swapped out R7010, as it was reading low, but now the new resistor is reading low too, so there must be a short near by...
Everything seems to measure okay, but I just wanted to describe this behaviour I haven't seen before..
If I plug the charger into my laptop, it goes green. Plug it into the 820-3462, and it goes green.
Plug the power into my laptop again and the light goes orange (mines a little flat now), plug it into the 820-3462 and it goes orange. :|
It seems the light does whatever it was doing last. :/
Any ideas?
