I have a Samsung 700t slate that I upgraded to win8 pro. once in a while, i.e. every other day or so the lock screen appears to be hung in that it wont slide up. the computer still seems to be alive as the cursor is visible on the screen when I have a mouse plugged in, the volume slider appears when I adjust the volume, and the autorotate button displays the message when its button is toggled. I haven't tried an rdp connection to the machine yet when its in this state. I've installed all updates from winupdate and have all the Samsung drivers installed through the Samsung driver tool. I've seen people report similar issues, but in those cases they seem to indicate that the machine is completely frozen. from what I can tell, i'm at least partially alive. anyone seen anything similar?to recover, I need to do a hard reset, but even then it takes at least a couple of times of full power cycling to recover to the point where the lock screen will work again.
