Hello

I am working to tackle a huge issue for our campus. We are having trouble with Windows 7 computers going to sleep and not waking up.

Here are the details:

We use Dell Optiplex 755, 960, 980 and 990 computers across campus all running Windows 7. We use SCCM 2007 to deploy updates and Remote Desktop Gateway for RDP.

We have the BIOS configured:

Wake on Lan
Auto Wake Daily at 2:45-2:58am
Disable Low Power Mode
On the 990, we have disabled additional C states.

Inside Windows 7 we have set the Network card to "Allow this device to wake the computer" and we allow anything to wake it, not just a magic packet.

Despite these settings, the computers are not waking on lan for SCCM or Remote Desktop, and sometimes will not even wake up for the user at the desk and have to be power cycles. It is hindering our ability to deploy updates and manage computer labs.

What are we missing? We are looking at implementing Intel VPRO management.

We use onboard NICs, I have proposed doing a test using a PCI nic since it's my understanding the PCI bus can wake a computer that is fully powered off.

Could it be "hybrid sleep" preventing the onboard NIC from waking the PC?
