Ok so I have a MacBook (white) and I’ve tried doing this. I’ve had the same problem as the wont sleep thing, but for about a week. Yesterday, I was about to go to the Apple store and try to fix it, but I got it working last minute and didn’t go in. Well, I started getting these restart messages every time my computer did start working, and had to keep doing this until the computer just gets stuck at the white loading screen with a grey spinning wheel under an apple sign(grey) also, this computer has the rounded edges and no, does not have the removable battery. Help!!!!!!!!!

If following these directions does not work, try powering down, unplugging, then doing the shift, control, option, power thing then restart. Worked for me when the other didn’t.

[...] I’ve gotten in the habit of immediately putting my MacBook Air to sleep by shutting the lid, by far the easiest method if you’re on the go. Typically this works without a hitch, but today the Air didn’t sleep when shut. Because the MacBook Air has no moving hard drive or sleep light, I didn’t notice this until I went to use it again about two hours later when I found the machine to be unusually hot to the touch because it never slept as intended. From there on it became a repeatable occurrence, and while I’m not sure of the cause, the solution was just a matter of resetting the SMC: [...]

OS Lion is destroying Mac Book Pro batteries. Not only is battery life diminished by about 50% but the extra load on the battery is killing the battery itself. Apple is doing their best to deny replacing the ruined batteries but at some point the pressure from customers will make them face this issue, or litigation will.
