Question How to re-enable laptop screen

[eynos]

Hi,

For work I usually disable my laptop screen, as usually it is connected to a dock that is then connected to two monitors. I simply use the laptop for its keyboard.

Now I've visited family and realized I didn't re-enable my laptop screen before I left home - how on earth do I re-enable it so I can actually use my laptop tomorrow for work!?

It's a DELL Latitude 7400

When I boot up I can see the DELL screen, but as soon as it loads onto the Windows 10 login screen I lose my display.


Please any suggestions?

Many of these laptops have a function switch to switch between external monitor and internal display.
Function + F8, maybe?

Doesn't seem to do anything, the F8 button does have an icon as a screen, but screen is still blank when I tap it, or hold it.

Try with and without function button as it will depend on how your BIOS is set.
Have you tried booting into safe mode to see if it's still blank.
