Question Dell Inspiron boots but screen doesn't work (external monitor does)

Hi, I have done a fresh install of Windows 10 on a Dell N5050 the screen worked fine through the installation process but now will not come on once Windows has loaded. If I connect an external VGA monitor that one works fine. When I click on "Display Settings"->Detect" it only finds the external monitor.

The process is: power up and the Dell screen comes on, then Windows 10 logo on a black screen appears with the rotating dots as Windows loads. Once that is done the screen backlight is on (light around the edges) but the screen is black. I then connect the external VGA and can complete the log in process.

I thought it might be a driver issue I could roll back but under Display Adapters there is only an Intel HD Graphics 3000 entry (and roll back is greyed out) and only the Generic PnP Monitor under Monitors

Thanks but yes, I have tried that. The Laptop screen is greyed out and each option has the same result - picture only on the external monitor

Problem solved! I had a suspicion it might be a BIOS issue, after updating the firmware the screen is now working, thanks ColGeek for your help.
Cheers
