laptop sleep mode

[Guest]

When I close the laptop it goes into sleep mode. However, when I open it up,
I get a blank screen, and even with moving the mouse, can't get the screen to
light up. I usually have to manually shut down then reboot. How can I correct
this? Thanks!

Thank you, it did help! In reading and "playing" around in Power Management,
I was able to fix the problem. Thanks again!
