HTPC unable to go back to S3 sleep mode after it's been WOL'd

-edit, Resolved! Check out post 12!

PC 1: HTPC
PC 2: Office Desktop

Mission: To leave HTPC 'on' 24/7, allow it to idle to S3 (suspend to ram) when not in use, but also allow it to WOL (wake on lan) via a magic packet request from the Office Desktop so I can transfer files to it when needed.

Accomplishments so far:
1) HTPC successfully idles to S3 when it's the only computer that's been turned on (Office Desktop is off)
2) Office Desktop can successfully WOL the HTPC

Issue:
Once I've WOL'd into the HTPC, the HTPC will not idle back to S3. It'll turn off the display, the the fans are still running.

I'm guessing I need the HTPC to someone realize that even though there is a connection between the HTPC and the Desktop, that connection can be severed as it is no longer needed.

Is there a way for the HTPC to 'time out' or have I not setup something correctly?

I guess my last resort is to figure out a way to "SOL", send a Sleep request over the LAN to the HTPC to put it back to sleep after I've WOL'd it???

TIA (Thanks in Advance!!! :woot: )

Oh and yeah, Mobo is a ZOTAC GF9300-A-E LGA 775: http://www.newegg.com/Product/Produc...-019-_-Product OS is Win7

What amount of RAM is present? What Operating system are you running on the HTPC, and is it on the latest BIOS (motherboard)?.......

4gb-512mb for the onboard 9300 = 3,584mb
Win7 Premium
I have no idea, assuming the latest. Zotac's bios version / update is a PITA to figure out, I gave up.

How about looking into some 3rd party app that scans the processes, and shut down the ones that are not on the white list and any others that show no activity after a set of time?

cheers ...

Running CMD as administrator and then running: "powercfg -requests"

I get:
Quote:
DISPLAY:
None.

SYSTEM:
[DRIVER] \FileSystem\srvnet
An active remote client has recently sent requests to this machine.

AWAYMODE:
None.
So that's my problem, I need to make my remote client (my office desktop) go 'inactive'

Well if I override it via "powercfg -requestsoverride DRIVER srvnet System" it'll allow my HTPC to goto sleep.. HOWEVER, it'll also go to sleep when I'm transferring files to the machine or streaming video from the HTPC

LoL... why is it so impossible to get this stuff set up!!! This shouldn't be this hard M$!!!

A small script to start and stop the service at the time you want? Override at end of file transmissions?

cheers ...

I'd love for it to idle down by itself 'automagically', but if worse comes to worse I could live if I could send a "SOL" ie a 'sleep over lan' request.

Basically do the following:
WOL the HTPC up
Transfer my files back and forth
SOL the HTPC to sleep

However, I have no clue how to send a 'S3 sleep to ram' request over the network.

Hopefully a few members can come by and help out with some CMD programming. I am no good at this

Moving your thread to Software General.

cheers ...

Well, the most up to date BIOS appears to be around 2008... The board may have an ACPI issue and not run the power module quite correctly... Update the video drivers, update the motherboard chipset drivers (use the nvidia website, not the Zotac site - they are usually old) and see what happens from there... One thing to do is to stick an old hard drive in and install Ubuntu to the system, update it and then see if Ubuntu does the same thing... If that works fine , then win7 is the issue, even writing a script may not do it....

Well I'll be! It's resolved!!!

Last night I was transferring some files to the HTPC. Normally I manually turn it off after I've finished transferring. Well, last night I went to have dinner instead. I came back an hour later and the PC was in S3 mode, fans weren't spinning!!!

I was like WTF? So I replicated the steps several times. Come to find out, the HTPC will try several times to go into S3 mode!!! So, I'd finish a transfer, or streaming and the HTPC wouldn't initially go to sleep, but then after around 10 min or so.. BOOM... it went to sleep!

Groovy!!!

Cool... Saves a lot of messing about... Typical software issue by the looks of things, few reboots to sort out...
