Hello !

Currently expieriencing an issue on my Dell Precision 7510.
I left it on during the night and if im not mistaken locked it.
Next morning trying to turn it on I was met with a black screen with no sound of it being turned on.
Suprisingly an relative of mine experienced the same problem this day.

After D + Power button the LDC screen flashes the appropriate colors.
After Ctrl + ESC + power button the power button flickers every 5 seconds or so once and seemingly tries again until Ctrl ESC get released.
None Of the F1 F2 F12 buttons do anything.
Removed the battery, held the power button for 30 seconds put in the AC nothing changed.
That was the recommended fix i found tho i believe it could be something of a Malware or an bad update since my relative experienced the same issue.

    Hello,

    Welcome back.

    Turn on the laptop and repeatedly press the F12 key to launch the Dell diagnostic tool -> Full Test. Follow the on-screen prompts and let us know the result.

    If you are unable to even see the Dell logo screen when you start your laptop, then, there is either a problem with BIOS or the motherboard.

    Connect an external screen or TV to any available video output port on your laptop, are you able to get the Dell logo to appear on that screen.

    If you are able to see the Dell logo screen, press F12 or Fn + F12 to open the Dell menu and run Dell Diagnostics from there.

    If you are still unable to get an image on the screen, you will need to take your laptop to a PC Repair Shop, the BIOS may need to be re-flashed.
