Hi, We are running Windows 7 Enterprise, fully patched on Dell Optiplex 745, 755, 760, and 980 computers and I can duplicate this on all of them. I go into Device Manager -> Network Card -> Power management. Check the boxes that we want. Close Device Manager. Reopen Device Manager to check that the change took. It did. Reboot. All Power Management settings for the nic are now unchecked. Normally we run a script to do this, but it doesn't matter whether you make the change via script or by hand, the Power Management settings always revert back to all three boxes unchecked after a reboot. As long as the computer isn't rebooted or shut down, the setting sticks for at least several days, the longest time we've tested. I found one thread that said this was a known issue, but the link to the answers.microsoft.com page came up 404. Any ideas? Here's the script, but like I said, it doesn't matter whether by script or by hand.

Hi, Have you tried reset BIOS? Does this issue occur to other PCs except for Dell? If only Dell PC is involved, it is recommended to contact Dell and ask if they have an updated BIOS.

It happens with the defaults right out of the box and with the latest BIOS and with all of the wake on lan settings checked. Unfortunately for testing, we are an all Dell shop so we don't have anything to compare it to. But I can duplicate it on multiple Dell models.

D'oh. No reason I can't test this on my personal laptop. I have a two year old Gateway tablet, also running Windows 7 Enterprise with intel nics. I get the same thing on the gateway as well. So Intel nics on Dell and Gateway combined with Windows 7 are the problem. The nics don't have this problem on computers still running XP or Vista. Guess we stick with XP at work until support ends in 4 years. :)

Hi, What is the exact model of your network card? I suggest installing the latest driver from Intel offical website instead of the OEM's website.
