I have inherited an environment which has recently migrated from XP to Windows 7 and discovered the WOL configuration was not properly set. The BIOS configuration is fine - no need for any configuration change there. However it appears the images used for the Windows 7 migration all have the "Allow the computer to turn off this device to save power" enabled. This is causing various issues with WOL as well as certain applications. 

The Advanced Property's of the NIC are fine as well - just need to disable the power management.

I thought perhaps using the K1000 to change registry settings would be the way to go however having difficulties with that.

Would anyone possibly be able to provide some guidance on this?

  • There are many, many scripts - not KBox, admittedly - which can do this using WMI. For example: http://powershell.com/cs/forums/t/2286.aspx
  • Thanks for the suggestion - I can certainly make that work with the K1000.

the registry Key is different from computer to computer.  VBScab is correct wmi or PS scripts are the way to go.  You can take one of the scripts and turn it into a kscipt and deploy it.  There is also a fixit on this link that may work for you.

I setup a script on our KBOX 1100 to set the registry options.  See here for more information:



It works quite well and prevents the machines from going back "to sleep" after the 2 minute interval.

I first push Power Settings via KACE then WOL BIOS settings (created via the DELL CCTK) followed by the registry settings for the NIC power management.

  • Good suggestion but that does not solve the problem in the question though. They are asking about the nic sleeping not the machine.
    • Ahh...you're right. However, I was posting about what I did here to keep the Power Management settings enable but allow the computers to be "woken up" via Wake On LAN from KACE. When the computer is hibernated, sleeping or powered off, the LAN adapter is still active and will accept a WoL packet. If the OP really wants to "disable" the NIC power management, have a look at the "GPO and regedit" section here:

Is there some reason you can't use the Power Management Wizard in Scripting > Configuration Policy, in the K1000?  We've got some excellent power settings related KKEs you can watch (http://www.kace.com/kke).

  • I do not see any options in the configuration policy you are referring to which deal with the network card - also the link you referred to is invalid.
