Steps to reproduce the problem:
1. Open chrome in windows 10 on system with 2 displays
2. Set power management to turn off display after 1 minute
3. Wait 1.5 minutes
4. Run powercfg -ENERGY from admin command line, look for an error caused by chrome

What is the expected behavior?
Both displays should shut off after user-programmable period of time.

What went wrong?
Chrome apparently ignores Windows requests and somehow keeps both monitors awake.

Current workaround is to:

(1)run "powercfg /requestsoverride PROCESS chrome.exe AWAYMODE DISPLAY SYSTEM" from admin command line, which disables Chrome's ability to keep the system awake.

or

(2) quit chrome before leaving workstation

I believe this problem also impacts single display systems.

Did this work before? N/A
