Windows 10: Laptop display fails to sleep when idle. Powercfg /requests shows that Edge is the culprit...

Edge is frequently preventing my display from sleeping which should then present the lock screen on wake. Powercfg shows that Edge is "Capturing". I have been unable to find any details on this power request - what it is and what it does - and I've not found a way to disable it. C:\WINDOWS\system32>powercfg /requestsDISPLAY:[PROCESS] \Device\HarddiskVolume3\Program Files x86\Microsoft\Edge\Application\msedge.exeCapturingCan anyone explain what Edge is doing when it is "Capturing"?

Windows 10 won't sleep: "Legacy Kernel Caller" in PERFBOOST section of "powercfg -requests" at fault?

Today, my Windows 10 just won't go to sleep.

Running "powercfg -requests" shows:

DISPLAY:

None.

SYSTEM:

None.

AWAYMODE:

None.

EXECUTION:

None.

PERFBOOST:

[DRIVER] Legacy Kernel Caller

Power Manager

ACTIVELOCKSCREEN:

None.

I can (and did, to no avail) add "Legacy Kernel Caller" to "powercfg /requestsoverride Driver "Legacy Kernel Caller" system", but it's not in a SYSTEM section, it's in PERFBOOST, and "powercfg /requestsoverride" has no option to
ban a request from there. I found that "powercfg /requestsoverride" actually just manages the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerRequestOverride" registry branch, and tried adding some more extensive bitmasks (0xff, why not?),
but I only managed to override DISPLAY, SYSTEM, AWAYMODE and EXECUTION - nothing on PERFBOOST.

Of course no USB devices are allowed to wake the system up anymore ("powercfg -devicequery wake_armed" is empty), the power plan option allowing timers to wake the system is off.

How do I get it to sleep again?

 

My computer's "Sleep after X" sleep is deeper than manual sleep

Thank you for the reply.

The troubleshooter made sure the power plans didn't have any issues (It didn't), but I've more or less resolved my problem by updating the requestsoverride list.

I use an old sound card (Soundblaster) with community drivers (kX drivers). The drivers interface with the card through MIDI somehow (According to the developer), which registers as an active sound stream.

In the future you might want to suggest users check powercfg -requests, where this was listed for me.

I added an override for it with powercfg -requestsoverride DRIVER "drivername" SYSTEM, and now sleep works most of the time if I shut down the driver config application first.

In powercfg -sleepstudy, this high sleep state was listed as "working", which is to say media playback paused and monitors off, at minimum, but the system was still actively running.

KX Driver preventing win7 from sleeping when idle??

If this feedback can somehow make it to any relevant team, there really should be some powercfg option or other tool to direct the computer to sleep immediately regardless of potential scheduling or active power requests.

 

powercfg -requestsoverride errors

Did you run the command below to check your command. If the powercfg /requests shows the Realtek driver it use whatever it shows, as indicated by the listing after using the command.

powercfg /requestsoverride /?
