Desktops & All-In-Ones

[staceypruim]

I was online with someone in a join.me meeting and my laptop screen just went blank.  I've done all the switching possible with the Fn and F5/F6 and when I choose the display for the device rather than external monitor it switches, but it's blank.  Start it up without screen attached, still blank.  But the computer itself is running fine as I can use the external monitor without issue.  I just upgraded to windows 8.1 last night.  Any ideas?  i've seen some talk in google look-ups of flashing the bios but wasn't sure...

I was wondering if the behavior you had described happened on other applications you run on your laptop?
