So trolling throughthe BIOS we find:
Wake on LAN from S5 is Power On
EIST (speed step) is enabled for additional power savings
Suspend state is S3
The 'Wake system from S5' option is a clock based startup feature (disabled)
Back in the windows NIC adaptor properties:
The power management tab is showing, so WOL is enabled in the BIOS.
Allow the computer to turn off the device to save power is checked
(wake on lan still seems to work anyway)
Allow the device to bring the computer out of standby is checked.
Only allow management stations to bring the computer out of standby is checked.
(wake on lan still is tested to work)
A couple more settings in Windows:
Here on the advanced tab we can check that only "Magic Packet" is selected and not "Directed Packet" which tends to bring the machine out of standby any time it receives a broadcast packet.
This is the Wake on Link setting. It's disabled. Strange idea. Suppose you could boot 100 or 1,000 PCs by just turning on your network hub this way.
