Comp will not sleep; icssvc to blame, but how to fix?

Hi all,

I just recently have started having sleep issues. I put the comp to sleep via either the power button or windows->power->sleep, and while the screen goes blank for a few seconds, the lock screen comes up right afterwards. This all started happening after I used Mobile Hotspot for the first time.

I've tried going to Services and stopping the Internet Connection Sharing Service, but icssvc still seems to be requesting something from the system (see below). Sometimes after a while, icssvc stops showing up in powercfg -requests, and at that point the system will sleep successfully. So, I'm quite sure something about icssvc is the root cause.

Any thoughts on how to fix this?

Thanks!

Thanks @Caledon Ken... I'm a bit reticent to nuke my network... want to try to sniff this one out before hitting the red button too quickly... I tried to stop icssvc with the CLI when I was having the problem recently, and came up with this message. Not sure if it gives any more clues...

Code:

C:\WINDOWS\system32>sc stop "icssvc"

SERVICE_NAME: icssvc
        TYPE               : 20  WIN32_SHARE_PROCESS
        STATE              : 3  STOP_PENDING
                                (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)

One further update with some info... I still haven't managed to lick this problem, but look at what I get when I turn mobile hotspot on and off a few times:

Code:

C:\WINDOWS\system32>powercfg -requests
DISPLAY:
None.

SYSTEM:
[SERVICE] \Device\HarddiskVolume6\Windows\System32\svchost.exe (icssvc)
[SERVICE] \Device\HarddiskVolume6\Windows\System32\svchost.exe (icssvc)

[SERVICE] \Device\HarddiskVolume6\Windows\System32\svchost.exe (icssvc)

EXECUTION:
None.

PERFBOOST:

ACTIVELOCKSCREEN:

icssvc seems to have gone full zombie, and is hanging on something. Mobile hotspot is creating new processes as needed... I updated wifi drivers, chipset drivers, etc, but that hasn't changed the behavior at all...
