If I'm away long enough, my PC is a deep sleep.  When I hit the kb or mouse it doesn't wake up. I hit the power button and it starts to wake but doesnt actually get back to Windows.  I checked the BIOS to make sure USB mouse and KB were selected.  Any other ideas?  I'm running 64-bit 7.  
I eventually just hit reset and get "Windows Rsuem Loader" and I will delete the restoration dta and proceed to system boot menu.  Thanks again in advance.
