My laptop starts up but immediately shuts down. However it works perfectly if I connect an external monitor. The main display never comes on.
I have tried reseating the drives and memory.
I have taken the battery out and unplugged the power supply. Then held the power button for 60 seconds.
The screen has no image not even a faint image.
I have ran the Dell diagnostics and no errors were encountered.
The screen was working fine and all of a sudden went black. When I restarted it that is when it failed.
On a side note the left click on the palm rest also stopped working. The right click works and so does the pad to move the cursor. Not sure if its related.
