Wake HP 8540w Display

I have an HP 8540W.

Windows 7 64 bit Ent

16 GB RAM

Core I7 Processor

Nvidia Quadro FX 1800M



Whenever my laptop display goes to sleep I can't turn it back on. Note, the laptop is still awake and all lights on keyboard work correctly.



The only way to recover from this appears to be to Force power off and then power back on.



Any help appreciated.
