Hi,

I thought I would post this in case anyone has this problem and fix. My laptop was working fine yesterday and when I turned it on today (21st Jan 2019) I had no display on the screen. I knew it was working as my mouse has a light and that was on. So I turned it off and on and still no display on the laptop screen.

Solution Plug in an external monitor and that display was working. I checked the software updates and noticed that Microsoft update KB4023057 was installed yesterday. So I uninstalled that and then shutdown the laptop and then turned it on again. Now my laptop display has come back

Hope that helps
