    I am the proud owner of a 2.53 GHz Macbook Pro for 10 days now. and it has happened twice already, that I - after working on it for a while - close the lid, put it in a bag..... and it gets HOT!!! as in: burning hot! while in sleep mode - how can that happen? the first time it woke up immediately, started fanning and everyhting was cool... or at least cooler..
    today it did not wake up, i had to force it to shut down, and then restart it.

    should i worry and take it back, or did i do something wrong?

    it probably didnt get into sleep mode properly and the airflow was blocked by your bag making it hotter. in sleep mode all thats powered is the RAM and a few little components so you can resume exactly where you left off after waking. it should seem as though its off as the hard drive and fans spin down.

    give it a fresh restart and then just make sure it goes to sleep properly in the future by listening to the fans turn off and waiting for the sleep light to turn on and pulsate.

    if the same behaviour continues try resetting the PRAM by holding command-shift-P-R until the second startup chime. dont do it otherwise.

    He should be able to close the lid and stick it in his bag without the machine getting super hot. That's what we all do with no problems. Hey OP, there's a ton of threads about the heating issue on this board. Do a search.

    yeh if his (her?) MBP went to sleep normally it certainly wouldnt get hot when put in a case. it will cool down as the hottest components arent powered.

    but what im saying is sometimes a MacBook may not sleep properly (software hiccup?) and the components will continue to run (screen may turn off) causing it to heat up as the case blocks the exhaust vent at the back. its rare but can still happen, happened to a mate of mine.

    just make sure it goes to sleep properly or if it continues to not sleep reset the PRAM.

    ^^^^ Oops, anna is a girl. :p You're right, it could be an issue with the software as a lot of these new MBPs are having issues. And the bag block the airflow.

    I always make sure mine's really asleep first. It takes a few seconds in order for your MB to prepare for deep sleep in case the battery goes dead while in sleep mode. If you waited and then there is still a problem with sleep, then I'd start to worry. Who knows what happens if you start jolting the HD triggering the motion sensors or futzing with the lid while its preparing to sleep.

    hi guys (girls too?),
    yep, i am a girl.
    thank you so much for your replies.. i will watch whether it really sleeps and then still gets hot... i was in a hurry yesterday, so maybe i did not really wait long enough... otherwise everything works great, so i would hate to take it back, i figure once you start exchanging stuff, it might be the beginning of endless repairs etc...
    let's hope i was just sloppy...

    I'm a girl too. :p Maybe you were in a hurry and didn't close the lid tight? Sometimes I notice that when I'm in a hurry and close the lid, it closes but doesn't click shut.

    The good side of the grass.
    I posted this before in the Air forums but I had a similar thing happen to me when I first got my Air. It turns out it was opening inside my briefcase and turning on. The magnetic latch would sense it opening a little bit and initiate active mode and then it'd shut quickly because I was jostling it around and it got confused. Got a tighter briefcase.

    There's also been a few posts in the MB forums of new MB's not going into sleep mode properly when moved. Fine when stationary though.

    it happened again....

    hi, i happened again. this time, i wanted to wait until it was really asleep, but it wouldnt go to sleep after closing the lid!
    so i wanted to wake it up again, to shut it down, but i couldn't bring it back to life except with a forced shutdown=restart. now everything seems fine again.
    mac os x gave me the following error report (which i don't understant... does it describe the crash or does it maybe only describe my force shutdown?):
