Power save for nic

[zeezam]

After a fresh windows 7 install on laptop I have to uncheck "Allow the computer to turn off this device to save power" for the wireless driver.

Is there any solution to do this with a command?

zeezam, I used RegShot on my W7 x64 Ultimate to see if it would find the secret. The following key is involved:

Changed values (2) for shot A

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0007]

"PnPCapabilities"=dword:00000118

"PnPCapabilities"=dword:00000100

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0007]

"PnPCapabilities"=dword:00000118

"PnPCapabilities"=dword:00000100

The first value for PnPCapabilities (0x118) unchecks "Allow the computer to turn off this device to save power" and the second value checks the box. You will need to run RegShot (or something similar) on your machine to identify the key since the name contains a GUID, which is probably different for your machine/NIC. I do not know if this value changes from install to install and you may need to search the Registry for the GUID to see where it is assigned to your NIC card. Good luck, John.

Just for the record, the GUID is for Network NiC's:

The actual \0007 part in your example will probably change:

Though curiously enough this report has the same \0007 :

And also this one:

This latter has a batch that may be useful as inspiration.

I'm using windows 7 32bit oem images. What program do you run regshots with?

zeezam, the same program. It has two folders, one for 32 and one for 64 bit. This link is in Russian, but you can find English sites and the program supports English (and other languages). Enjoy, John.
