I left the sleeping beauty charging until full. Grabbed it and put it in it's plush feathery padded sleeve for transport to the lab where I gently set it down until needed roughly 4 hours later. When I took the thing out of it's padded case it was burning hot and the fans were on full speed. I opened up the mac and it had gone into some emergency hibernation grey-scree mode. Then started up fine but only had 20 minutes of battery left and the fans were going at nearly 7000 rpm's! WTF happened? I couldn't help but think that this could have fried the battery or internals but all seems well a week later. The battery health is at 96% etc. etc. Any ideas? Again, it was just a normal close the lid sleep, charge and unplug procedure.
