Screen doesn't turn on after resuming from standby- Windows XP

Question

Hi all,
I have a Lenovo 3000 N200 with Windows XP SP3 (recently installed xp), and my laptop goes to sleep fine, but when I try to wake it up from standby, the computer turns on fine, but the screen does not turn on at all. The hdd LED shows that the hdd is doing something, but the screen does not turn on at all. I've tried pressing keys on the keyboard, moving the mouse but still no luck. So since I cannot get my laptop out of sleep, I have to hold the power button and power the laptop off and then back on again. I do not wish to keep doing this since you can corrupt your hdd by doing this too much.
Any help would be highly appreciated..
Thankyou,
From Dean.S
