My mac won't wake up from sleep, what can i do Something to check -- are you sure it is actually sleeping? Don't take that question the wrong way. I ask that because my machine has had a history of bad video cards where the card fan would stop (or never start) and the machine would go into a thermal cutoff (I'm on card #3 now). The thermal cutoff looked exactly like the machine was sleeping, i.e., everything looks off and the power button is pulsing. But unlike a real sleep, there was one exhaust fan in the back near the dimm slots still running. So the next time you get into this 'sleeping' situation, open up your machine, and check to see if that fan is running. As described above the moral equivalent to 'pulling the plug' on your machine is to keep the power button pressed until it shuts down. Also it might not hurt if you did a. Can you say more about thermal cut-off? My mac has beene having problems waking from sleep and I have noticed that I hear the fan running ever so slightly in the background.

What else could it be? Without its fan video card would get extremely hot and throw off all that heat. Whats the point of having temperature sensors in so many places other than to use that info to protect the machine against damage due to overheating? So my assumption was card gets hot, sensor (probably the pci slot 1 temperature sensor) senses it, kills the machine. It's also seems logical to me that the circuit(s) handling temperature overloads would want to keep a exhaust fan running to dump the heat out of the machine to further protect any damage from the heat.
