Took my 2012 MacBook Pro into shop for diagnostics after small water spill. Instructed that will only turn on when power is held down for several seconds and then MagSafe charger is plugged in. After 11 days shop called. Reported they were unable to power MacBook on - apparently front desk staff didn’t tell them how I’ve been powering it on. Diagnosed “motherboard replacement and MagSafe replacement ($875) + labor and 240GB SSD ($200). My question is is it possible to come to this conclusion and recommendation when they never even turned computer on?
To answer your question, if they didn’t even boot it they don’t know. Different shops have widely varying levels of competence. First how much liquid got into the machine and how did it enter? If it came in via the keyboard and a small amount like said, but it will boot after the battery and mag-safe adapter are disconnected then reconnect, then I suspect a logic board and DC in port won’t help it at all. Tell me if it runs OK after you boot it? How’s the trackpad doing? Now for what I suspect, do all the keys work? Will an external keyboard and mouse work?
