    It just started getting really hot quickly for about a week before it didn't turn on. I would have it tilted so that its not flat, hoping that it would give it more air but it didn't do anything. I don't even need to do much to get it really hot. And I shut it off every night, so it should get to reset itself. I haven't done anything different that I haven't before. Any fixes please!? Also what's really weird is that it gets hotter and hotter even when it is off and not even plugged in. :confused:

    Hrm. Sometimes my old machine would go into sleep mode, but not really. It would be unresponsive and RED HOT. I usually discovered this after a long walk to school. I'd also have a seriously depleted battery. I can't say I have a fix for you, but if your machine is not plugged in and getting hotter then it sounds like a failure to properly sleep. Just hold the power button down for about 10 seconds to turn the machine off. After that just start it back up. In my case I believe it was a faulty bluetooth module that was waking the computer up from sleep every time it disconnected/reconnected (it connects via an internal USB connection). I just disconnected the cable and that eliminated the problem.

    Note: If you hold the power button down to shut it off you will lose any unsaved work, but by this theory your machine has already crashed, so it's probably lost anyway :D



    Good luck!

    It seems that the battery may have been a big part in the problem. Once I switched batteries, it wasn't hot anymore. Then I did some looking around and performed the single user boot, and with the fsck code it fixed the problem. I'm really happy right now:D:D. Hey do you have any suggestions on how to keep it cool? I know not to put it on soft surfaces, I'm thinking software like G4 fan control (but don't know how to use it), or maybe even a cooling pad.:

    iCyclone might work.

    I use a cheap little cooling pad I got somewhere for around $10 on my PowerBook, and it works great. The internal fan rarely has to come on :)
