After pressing ctrl-alt-del, entered my credentials & hit ENTER into my Windows 7 Professional on X230 laptop,
occasionally the Desktop is complete dark/blank.
It responds to & launches the Task Manager if I press ctrl-alt-del : while in Task
Manager, I go to "Run" & enter "cmd" & at command prompt, issued "explorer"
as well as "dvm" (desktop manager) but they were never displayed in the desktop.
I've tried killing the dvm process & launch it at command prompt: could see the process 'dvm' in
Process List in Task Manager but nothing displayed.
Usually I wud power cycle & about half the times, the Desktop would recover/normalize: but at
half the times getting a blank dark screen is highly unproductive : it took almost 25 secs to boot
up even though I'm on a full SSD (Crucial brand)
This SSD was moved over from an X220 to X230 but I recall for the first few weeks, I don't have
this issue till lately
