Name model: Precision 7720
Graphics Card: NVIDIA Quadro P4000 4.0 GB
I have 2 problems that I think are some how related.
1. The laptop screen shuts off after the proper amount of mins set in windows. The screen will not turn back on unless you reboot the computer.
You have to hard reboot it. If you LIGHTLY press the power button, it shuts down the computer. Normally you have to hold the button in for 10 seconds but this you do not.
It seems like it is in sleep mode but I have ALL the sleep modes disabled in windows and BIOS. The power button does not pulse like it is in sleep mode either.
We have found out this only happens on the docking station. It does not happen when the computer is undocked.
While trying to figure out this problem, we turned off the switchable graphics in the BIOS. This corrects the problem but creates a NEW problem where the 3 monitors flicker. We have found out that this does not happen off the docking station either. If the screen are flicker while on the docking station and you undock the computer, the flicker will stop.
What have I done?
Reset all display settings
Turned off all Sleep Modes in Windows and BIOS
Dell replaced the motherboard and graphics card
Updated the graphics driver and rolled back the graphics driver.
Updated BIOS
Switch out docking stations
Right now we are trying to use a new thunderbolt docking station to see if the current old style docking station is the problem
