DH87RL & Wake on LAN from ACPI S5

Hi,

we have two different DH87RL here, only slightly different hardware revision

newer: AAG74240-402

older: AAG74240-401

Both run under Windows 8.1 with same drivers (same driver revisions).  Also, BIOS Setup settings are identical. Of course, BIOS revision is same (0322).

But to our surprise, the newer model does not react to Magic Packets (WoL/Wake on LAN) in Soft-off-mode ACPI S5, while the other does.  On both platforms, WoL from ACPI S3 or S4 works fine.

We think we tried everything

- changed BIOS Setup settings

- changed PROSet driver (18.7) (uninstall/reinstall)

- changed settings for power management in Windows device manager

Any ideas?

Greetings,

Christof
