Dell: Latitude: 3520 Black Screen

If you run into a black screen but the power indicator is on. Please remove any and all power sources from the machine and let the battery run dead. Next plug in the power cable and that should resolve the issue.

Another Tip:

Disconnect any external devices including the AC adapter

Hold the power button down for 30 seconds (20 seconds for Alienware)

Bypass any power strips, surge protectors or battery backups

Verify the wall outlet is functional

Proceed to the next step

Plug only the AC adapter back into the laptop

Attempt to power on the system
