Whenever my Windows 7 laptop goes to sleep (either by automatically going to sleep automatically or by telling it to) it gets stuck.
It doesn't go into sleep mode, the screen goes black and it shows no disc activity from the light on the front, but the power LED stays solid green and not orange glowing like it normally does. I can't get it out of this state except by holding down the power button for 10 seconds and starting it back up again.
Recently I updated my graphics card drivers but I wouldn't imagine that updating would cause this issue.
I checked the windows event log and it reveals nothing relevant.
