When unlocking Windows 7 screen goes black
When I wake my laptop up from sleep mode, I get only a black screen. When this happens, I can see my cursor — which is responsive — and I can Ctrl+Alt+Delto get to the options screen... but all the options lead back to the black screen of nothingness. Nothing but the mouse movement and the options menu works. Even "restart" in the options menu does nothing.
The machine is a Lenovo T510 running Windows 7 Professional. My solution to date is a hard restart. Does anyone have a better suggestion?
