[QUOTE="mklasse, post: 687002, member: 32213"] Happened to me a few times, and bad grounding was the culprit for me. My laptop is the older PowerBook G4 with the same aluminum casing as the new MBPs, and I don't know about MBP, but Apple supplied 2 a/c wall plugs for the adaptor. The one with long cable and 3 pronged plug, and the "compact" 2 pronged plug. This usually happens to me when I use the 2 pronged plug (no grounding), and when my feet are touching the ceramic tiles floor (doesn't happen if i wear shoes) or when my hands are slightly damp from sweat. This also happens several times when I use the grounded 3 pronged plug, and I found out the a/c outlet has bad grounding because it doesn't happen when I plug it into another a/c outlet, and happens again when i plug it back into the original a/c outlet. Yes you didn't expect your $2500 laptop to run electricity through its frame and shock you, but i think what chscag meant was that you should've unplug the power cord when it shocked you the second time (when you knew your MBP is trying to kill you with electroshock ;D - jk) and when you tried to shut it down. Maybe you should try to plug it in at another outlet location in your house and see if it does the same thing. This time if it does, just unplug the a/c cord, shut it down then take it to Apple.
