    There must be a setting I'm missing -- when I lift my lid, the CPU wakes up but the screen doesn't -- if I close the lid, wait for the half moon light to shine and then reopen the lid, the screen wakes up. Anyone know what I might be missing here?

    Thanks.

    Video drivers?
    Power manager drivers?
    Check out whether you have recent drivers or whether you did some driver updates prior to this problem?
