Okay, I've been using Leopard on mu MBP since the day it came out (pre-ordered it), and up until now I thought I was extremely lucky, having not encountered any bugs. Until this morning. I was using my MBP at home to check up on a few things (and even browse these forums before having to get real work done) before heading in to work. As Murphy's law would have it, today is going to be a long day and myself and my MBP are working overtime, doing my usual A/V/Photo work during the day and then giving a 3 hour presentation/demo tonight. I'm not going to be done until about 9:30 p.m. In fact the only reason I'm typing this out right now is because I'm waiting for my MBP (which has today's presentation on it) to "cool down," for reasons that will become apparent shortly. Anyway, I was checking up on my e-mails and presentation before leaving for work, and as I was packing up, I shut down my MBP, and THOUGHT it had shut down completely. I've been noticing that since the Leopard upgrade, my MBP has been appearing to shut down very quickly, quicker than Tiger. Anyway, appearing to be completely off, I put my MBP in it's carrying case with sleeve, and drove to work. At work, it took me a while to take out my MBP because I was busy doing other stuff on my desktop (an iMac) here in the office. Finally I'm ready to go abck to tonight's presentation. I open my case, reach in and grab my MacBook, and very nearly burn my hands in the process. This thing is HOT! Apparently, despite my screen going black when I told the MBP to shut down, and NO indicator light on the front of the case (pulsing or otherwise), my MBP apparently had never shut down and never event went to sleep and was running the whole time, for about an hour and a half, inside its carrying case. I managed to pull the MBP out of the bag (after fashioning some "oven mits" out of some nearby foam sheets) and placed it on a notebook cooling pad I have on my desk, and set the pad's fans to their highest setting to try and get this thing to a sane temperature. The MBP was unresponsive: screen was still off, would not "wake" up, though the internal fans were blowing full blast. I was able to shut it down fully by pressing and holding down the power button. So now the obvious questions: 1. What kind of damage should I be looking for? Are there any logs I should be checking? Appearance-wise, there doesn't seem to be anything melted or heat damaged, but I'm concerned about hidden damage I'm NOT seeing. 2. Has anyone else experienced this? This has me totally FURIOUS. The work I have to do tonight is one thing; if my MBP isn't up to the task tonight, I have other alternatives, and although it will be really annoying, it won't be the end of the world. What angers me is that, after all the care I've taken to avoid so much as putting a scratch on this thing in the time I've had it, this Mac may very well be toast - literally - all because it didn't shut down when I told it to, despite it having APPEARED to have shut down. Even assuming there was no harm, I'm not going to feel right about turning this guy off again and storing it in its bag without pulling the battery. At any rate: after about 20 minutes of my writing out this rant, it seems to now be at a temperature when I can no longer cook breakfast on it. It appears to be booting fine. iStat Pro shows my fans running at 6000 RPM despite my CPU and case having since cooled down to around 50 degrees C, though it's since come down from that and the fans have since slowed. It appears to be running normally though I THINK (I'm not sure) that my display is a bit dimmer than it used to be, even if I set the brightness to full. Ugh. Now comes the paranoid period where I scrutinize every little thing and wonder if something's wrong.
