So just recently my macbook pro has been acting crazy.  When I put it to sleep now, it wakes up (I can tell by the light on the side) but the screen remains black.  So I try to restart it by force shut off with the power button.  When I turn it on again the screen remains black but I know it's on because of the light switch and I can hear that it is on.  There is no mac sound either like there usually is when you turn the computer on.  A temporary fix that I have found is that if I drain the battery and I plug it in again, it boots for whatever reason.  Anyone else know what my problem is?

MacBook Pro, Mac OS X (10.7.4), Early 2008

    Why not start with:


    Reinstalling Lion/Mountain Lion Without Erasing the Drive


    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.


    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.


    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.


    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.


    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

    I have a similar problem. My early 2008 Macbook Pro has nothing on the screen after I'd put it into sleep and then open the lid next morning. However, it's very hot and I noticed if I have an external monitor plugged in it has static picture on it with windows and stuff... The mac doesn't respond though. It works fine after a power off/power on.
