Performing an RTC reset to see if it may help.

1. Turn off the computer.
2. Connect the AC adapter to the computer.
3. Press and hold the power button (around 30-35 seconds), until the power LED blinks three times.
4. Release the power button.
5. The RTC reset is complete after the power button is released.

If the issue is persisted, you may consider to perform a BIOS recovery as your last resort.  Follow instructions properly  https://www.dell.com/support/kbdoc/en-us/000132453/how-to-recover-the-bios-on-a-dell-computer-or-tablet

Here is the latest BIOS release for your system.  Scroll down and select to download BIOS_IMG.rcv.  Put the BIOS recovery image file on a FAT32 formatted USB to use in recovery process.

Thanks for these. On the RTC it seemed to initiate in that the laptop restarted several times but didn't work.

On the BIOS recovery. After I unplug hold down Ctrl + esc plub back in keep holding the computer starts shows the splash screen not then just is black screen. The keyboard lights up when I move the mouse however

I think the system is working but with video display issue.  If you have access, test with an external monitor for visibility and roll back video driver to see if it may help.

Is this happening solely in battery mode? Or also when connected to the charger/mains. If the former, perhaps uncheck the HDR option under Display. If that works, restore HDR (if you want it) but with battery powered optimisation selected in the small fliplist.

I have gained access to an external monitor. I was able to access the recovery screen via the external screen. I reset my PC (cloud reinstall of windows but keep my files option). The reset has completed but the issue still occurs. 

When I turn on my laptop the dell logo flashes on screen but then black screen thereafter. If I connect it to an external monitor I can login. I tried playing with the external monitor settings. Duplicate screen extend etc however the screen always stays black. 

@Rastaris​ This is happening when connected to charger/mains. 

Any luck resolving this?

I have the same issue.. works fine at boot, works fine in bios or diagnostics, works fine with an external monitor, but won't display anything once windows loads on the internal screen.

Tried a reinstall of windows and it looked fine which it was using the basic VGA driver i assume, then cut out during the rest of the installation, but was fine via the external monitor.
