Windows only successfully wakes up from sleep mode about 2/3rds of the time.

On my Vista laptop, when it goes into sleep mode (for low power, or manually being put into sleep mode, it happens regardless of how), about 1 in 3 times it won't wake up properly from sleep mode, and just display a black screen. The only option is to hold the power button to turn it off by holding the power button, and turning it back on again.
(And yes, I have moved the mouse, pressed keyboard buttons and stuff).
