RE: Latitude E7440 black screen after undock

Jump to solution

same issue here, still.

tried with multiple different video driver versions (incl the latest), and yet experiencing the issue. not always, but very often.

usually screen is blank after undocking; or sometimes ok after undock, and then blank after (going to and then) resume from hibernation. it is super annoying.

DELL - please, is there a solution??

(win7 x64; When I close the lid: Do nothing; power settings reset multiple times)

Anyone know if this above fix have resolved your issues?

Me and a few of my colleagues have the same problem, and we have different Dell Laptops, where the screen is black, but my computer still runs. Since I keep many documents open, I'm not keen on rebooting each time it happens.

I temporarily resolved the issue by removing the external monitor (that sometimes mean un-dock), press Windows + <P>, press Right button, press Enter, and repeat until I see the screen again, after that I usually finish my work and then reboot.
