    iMac will not sleep and freezes ??
    My 20" imac Intel will not sleep. It goes into sleep mode for about 5-10 seconds and then comes back on. It also freezes when powering down about half the time. I already re-installed the OS (10.4) and that did nothing. Anyone have an idea of what's wrong?

    Nobody? Anyone think it might be the logic board?

    Specs:
    MacBook Pro | iMac(2.1 G5) | MacBook(2.16 C2D) | MacMini (1.67 CD) | iPhone 4 | iPad (3rd Gen)
    Sometimes it comes back on if a background application suddenly becomes active.

    Do a hardware test using your installation disks for errors.
