If your laptop appears to boot up and the hard disk LEDflashes or the LCD screen blacks out after a period, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :-

usually if you turn your computer on and the screen is black it is one of 3 things ram-memory,video card or the cable conecting the video card to the monitor often time the cable running from the monitor to the video card in laptops short out after being used for long periods
I'll asume something for this one it might help. Make sure your laptop is completely turned off [No fans turn, screen black, no hard drive light]. When you then press the power button, immediately keep pressing the F8 button on your keyboard. It should then actually display two options after a while :
*Delete restore/resume point and start windows *Resume restore/resume point
Select 'Delete restore point' and the unit should boot up fine again.
I had a unit that was basically turbo-booting into windows, but the restore point was corrupt and it always seemed it had a 'blank screen' problem.
You can also try to access the BIOS by pressing F2 as soon as the unit starts up to see if you can actually access the BIOS.
Good chance the is a power saver option if it happens while you are not actually using the computer..
The computer will turn off the monitor after a certain period of inactivity to save power.
Go to the Control Panel, select Power Options and adjust it to what you want.
When you say it turn black, could you try to see that ther are
still picture on it(maybe you've black light problme)...or just completely black .And do your laptop have any activity...say harddisk light still flashing,..etc..
Bye,takecare.
Over heating can cause a computer not to turn on, or turn off after a period of time. You might have some dirt and dust in your fan that you need to blow out with canned air.
You might also try a laptop cooling plate: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2427205&CatId=215
Have you turned off the hibernation?, that would be your first priority.
Check the settings again to make certain in the Power configuation has been set to never for all settings for both power abd battery for the time being use them and then try again?
