Q: Macbook Pro wont wake from sleep

My '08 MacBk Pro wont wake from sleep. This has happened several times since I installed Lion. In the past I have simply clicked several times on the trackpad until it woke, but on several occasions it actually shut down after entering sleep mode, (It went to black screen, the little pulsing sleep light was dark and I got no responce to clicks on trackpad or keyboard). When this happens I can usually re-start the Mac with a hard re-boot to resolve the issue. This time however, I can't get the computer to turn on. I've tried pressing the power button once, and all that happens is that the sleep light blinks once along with a the normal whiring sound you hear when the computer is ramping up, but this lasts only a second and then it goes back to black screen/dead Mac. I also tried holding down the power button as I would for a hard reset at which point I get several blinks from the pulsing sleep light and then nothing. I also tried unplugging the cable, removing the battery and pressing the power button for 5 seconds, then reconnecting battery and cable and pressing the power button, (I got these steps from an article posted here on the furums). BTW, I have disconnected all external drives, etc. before trying any of these steps. Please let me know if there's something else I might try to revive my Mac.

MacBook Pro, Mac OS X (10.7.2), Early 2008 Silver Keyboard

    Does this apply to you?

    Follow up: I took the MacBook Pro for repair and the tech found that the logic board was damaged - probably due to so many hard resets I had to perform to get the machine to load when starting it up after shutdown or restart. I replaced the logic board, (Very expensive) and its been running fine for 3 days. However, the freezing problem has just started again and I'm worried that having to perform a hard reset to get the macbook to load will cause more damage.

     

    The problem that's occuring is as follows: When I start the computer up after shutdown, or sometimes after restart, the desktop fails to load and the spinning color wheel appears. I can see the dock and the main upper toolbar but my desktop is blank and my external hard drives do not load. I can't make any selections with the cursor because of the eternally spinning color wheel, so my only option is to perform a hard reset by depressing the power button until the unit shuts down. When I start it up again the system loads correctly. I have tried ejecting my external drives before shutting down, but this doesn't make a difference. This problem started when I installed Lion OS and got continually worse until the computer finally shut down for good and I had to replace the logic board. Now it's starting to happen again.

     

    Has anyone else experienced this problem running Lion on a MacBook Pro early '08? If so, please help me find a solution for the freezes.

    This doesn't seem to be an issue on my unit, but thanks for letting me know.
