I have a MBP SR and it's been great so far except one major sleep issue. Basically..the MBP will not STAY sleeping. After about 20 min, the comp wakes up. Also, if you leave it on for about 10-20 min w/o touching it, the backlight (which automatically turns off after a few min) turns back on as if someone moved the mouse or something. It's getting kinda annoying. I tried this on a guest account too and same thing. Guest accounts have no software in startup, so its not a software issue. I also reformatted and reinstalled OSX leopard with no success. It did this under tiger too. You think this is a hardware issue? Should i take it in? Thanks!
