A friend of mine has a macbook pro that had some liquid spilled on it. The only problem that i can see is the keyboard doesn't work. It powers on ok and will work fine with an external keyboard. He's selling it for a great price and I wanted to get some advice on how much it might cost to repair. I'm assuming that since it powers up OK and works with an external keyboard it's not something major like the logic board. Could it be something as simple as buying a new keyboard. Any help/suggestions would be appreciated! Thanks in advance!!
