Product: HP Z240
Operating System: Microsoft Windows 10 (64-bit)

When the Z240 wakes out of sleep mode, video no longer comes out of the video card. Occasionally it does sleep/wake correctly, but this video problem happens several times per day, and I have to kill the power and restart to get it back. Even that doesn't seem to work sometimes, and I have to let it sit for an hour or so before it decides to show video again. I've tried the supplied video card (GT210), another video card (GTX 1060), 3 different monitors, upgrade to the latest BIOS... Nothing seems to help.

 

This is on a freshly install Windows 10 64-bit (1903).

 

Are there any BIOS settings or hardware changes that might help this wake-from-sleep video issue?  Since the video doesn't even show during startup, it must be a BIOS or hardware issue.
