    Dell Precision 7740 Sleep Mode - Black Monitors/Restart


    Alas, I cannot precisely the exact moment of the annoying changes in sleep mode.

    It is possible that an nVidia RTX Quadro 5000 driver could be a culprit.

    No configuration, apart that above, has been made to the power setting.

    At present after putting the laptop workstation in a sleep mode, the computer wakes up on the keyboard key pressed but the monitors are black.

    What is more bizarre when I turn off/on the first in a chain (dell monitor connected to the second) the laptop restarts.

    I have clean reinstalled the driver, updated BIOS - all in vain.

    I would be deeply thankful for any piece of helpful advice.

    Nvidia RTX Quadro 5000

    Two Dell additional monitors connected in chain and via usb type-c single cable to the laptop.

    YRCL hello and welcome to TF

    I would disable Windows "fast startup" and see if it fixes the issue. Next check your BIOS and drivers are all up to date. /EDIT see you said BIOS is current. How about all other drivers?

    It's possible Nvidia driver could be the problem. You could try uninstall and reinstalling it if other suggestions don't resolve it.
