So I've had two of this model give me the same issues. When booting the display shows the Dell logo and the Windows logo and then goes black. You can hear the Windows chimes but there is no display.
If the lid is closed and the computer goes to sleep then is reopened the log on screen is shown.
We have tried re-image and reinstalling all drivers in the proper order.
Updating BIOS and making sure that the video settings are correct.
No matter what we do every time the computer is booted the logon screen is black.
