I just started playing WOW a few days ago - now I am thoroughly addicted but today after two long sessions (about 2 or 3 hours each) the power cord on my Macbook (bought in July last year- not the aluminum one) quit charging the battery. The first time the computer simply shut down, and I noticed the mag cord light wasn't on so I figured I had an outlet problem, switched outlets and voila light came back on. The comp started back up and I saw the battery was at zero so just figured the outlet didn't work and the battery drained out without me noticing. Second time with the different outlet I realized immediately as I had been watching the mag cord light, light went off, now I know something is up with the cord. I unplugged it for a few minutes and it worked again. Is this some sort of auto shut off for the power cord? The brick itself is pretty hot (nothing too crazy- not even close to being too hot to touch), the magnet part where it connects to the computer is not hot at all, the processor isn't very hot (about 60 C) and I can comfortably rest the comp on my lap. Any thoughts on this? seems like a safety shut off after all the cord probs of the past.
