HD520 Screen keep blinking after waking from sleep.

When my computer wakes from sleep, the screen keep blinking. I am sure my laptop is sleeping. (power LED blinking). When I move my mouse, my computer will soon wake up, it seem that all other thing is normal without the screen. Is this a normal behavior, or do I need to fix something? Thanks. A...
