    This happens from time to time, but happened to me twice today. After I close the lid or the computer goes to sleep, I open the lid or press the power button to wake the computer up. The screen remains black. The keyboard lights will come on / off. I try pressing F2 to increase the backlight on the screen, and nothing. The PC is working because I can hear sounds and stuff from programs...

    The only recovery is to power off and turn back on. has this happened to anyone else??? Should I bring it to :apple:? I have had this for just under a year...

    This actually happened to me earlier today; had to hit the power button as well to wake it up-- my MacBook is about a year and a half old and this has happened maybe two or three times prior to today...never really thought much about it though....anyone know why this is?

    I've had this happen before on my two year old MacBook Pro (wow I can't believe I've had it this long...) but if you close the lid and let it go completely to sleep so that the light is flashing like when it's asleep. Then if you turn it on again, it usually works right away.

    same with me. i have a SR macbook pro, and the only solution is shutting it off (not a hard shut off, just hitting the power button and enter). i dont know how to fix it, but now i might just leave it open in the day and let it go to sleep by itself; and at night, just shutting it off...:(

    This usually happens to me 2-3 times a week depending on if I'm hauling the ol MBP to the library frequently or not. As listed above, I subscribe to the "open and close" method of solving this. Convince the computer to go to sleep again (I wait until I hear the dvd drive engage and disengage) and then open it up again. Most of the time this works on the first try, but occasionally I will have to do it multiple times.

    To be honest? I have absolutely no idea. As everybody else is saying, the computer acts like it is on just without a screen. But I cannot blame Leopard for it, because it happened to me under Tiger as well. I'm sure someone with more technical knowledge could correct me, but I would blame the hardware concerning how the motherboard routes power after being awakened from sleep.

    there are tons of thread in regards to this matter so you may find additional information on how others have attempted to fix this problem.

    Some people point the cause to iStat or Safe Sleep Mode. My 2 month old MBP had this problem so its now being replaced with the Penryn model since none of the Penryn model users are experiencing this issue.

    MacBookPro Screen will not come on after sleep



    My screen wil not come on after sleep. At first was self correcting but became increasingly frequent until it is now permenant. Apple had me remove my battery and push on button for 10 sec. Next push on button momentarily and push Command;Option P & R key simultaneously.

    I was to make sure that it was plugged into wall during all these maneuvors which were tried with and without battery in place. All to no avail.

    I am taking it to the Apple store on Weds nearby for expert help. My feeling is that this is a frequent problem that will require a replacement MacBook Pro.
