computer hibernation problem

when i put my computer into hibernation mode over night it wakes up as if i put it in sleep mode, it doesnt say "resuming windows" just black screen straight to log in screen, and it only happens overnight. kinda lost on this one, any advice/help?

Check the settings in Control Panel | Power Options. Some setting there may be overriding the hibernation.

i adjusted the settings, we'll see what happens tonight

problem solved
