Network Power management setting

I am trying to troubleshoot a network error in Third party software. They are telling me the network card may be powering off.  I find this hard to believe.
Question:
What does the NIC power management rely on? Does it rely on the system power settings?
Example: If the system power settings are set to never sleep or hibernate. Will the NIC power still turn off if the device setting are set to "Allow the computer to turn off this device to save power"?

In windows XP, "Allow the computer to turn off this device to save power" does apply to NIC cards.

Please follow this step to disable that 'feature' in Windows XP: http://support.microsoft.com/kb/837058



For Windows 7: http://technet.microsoft.com/en-us/library/ee617165%28WS.10%29.aspx

To turn power management features on or off

   1.   Open Network and Sharing Center (click the Start button, type Network and Sharing in the Start Search box, and press Enter).
   2.    Click the Change adapter settings link in the upper left of the navigation pane.
   3.    Right click the network connection you want to enable/disable power management support on and click Properties.
   4.    Click Configure.
   5.    On the Power Management tab, check or clear the Allow the computer to turn off this device to save power check box.
          * When checked, power management is enabled on the network adapter.

          * When cleared, power management is disabled on the network adapter.

   6.  You can enable Wake on LAN for all wake methods or just enable magic packet WoL:
          * To enable Wake on LAN for all methods, check the Allow this device to wake the computer check box.

          * To enable Wake on LAN for magic packet only, check the Allow this device to wake the computer check box and then check Only allow a magic packet to wake the computer check box.

Sommerblink,

So you are saying the NIC power management settings are NOT dependent on the system power settings?

To answer this question, yes.

This is why with my response(s) above, they have you turn off the 'system' setting explicitly for your network card...

Now, to be honest, I don't have an XP machine to test my first link on, but given the source (and my memory), I do trust it.... but I do see see the setting for Windows 7.
