Would you happen to know how to hot wire an 17" Macbook Pro purchased in August 2011? My wife spilled water on it, and it won't turn on with the power button. The Genius at the Apple store said he was able to turn it on, but he didn't verify if anything works beyond it just chiming. He suggested we send it to Apple to repair, but that we ought to back up the data first.
I could take the hard drive out and mount it externally on another machine (and just copy), however I'd like to try to power it on to see if it works, and try to run a Timemachine backup. Seems like a more reliable method than just dragging the files over. But I can't find any power pads, or a power symbol, and jumping pins 5-29 on the keyboard ribbon cable doesn't seem to work either. I'm out of ideas, help!
