On my Windows 7 machines in am using WOL fine with LogMeIn. The settings that I always have to do are as follows. These were the settings we used on our Dell OptiPlex 780.
Lower Power Mode - OFF
Onboard NIC (PXE/Other)
uncheck allow to sleep
I did have to change it a little when we upgraded to the Dell 7010 as the options changed. There was an additional option Deep Sleep Mode in the bios that had to be disabled.
I know you have some of this... thought I would just add our settings. Hope something helps
You can also use the following to make sure your machine is compatible with WOL:
This test will only work on Windows based systems. If you are unfamiliar with working with the command line, please seek further assistance from your administrator.
You will need to save the woltest.exe file http://lmine.ws/hkCYAV to the computer you're going to wake (the computer cannot be asleep at this time).
Open a command prompt and navigate to the directory where you unzipped the woltest.exe file.
Enter the command: woltest -info and press Enter. You should be presented with information.
Take note of the MAC address, Local IP, and subnet mask.
Sleep the first computer, move to another Windows PC on your LAN, and copy the woltest.exe file there also.
Open the command prompt and navigate to the directory where you unzipped the woltest.exe file.
Enter the command: woltest -wake -mac (the noted MAC address) -ip (the noted IP) -subnet (the noted subnet) and press Enter.
Example of the wake command: woltest -wake -mac 00:0c:20:1c:51:29 -ip 192.168.1.142 -subnet 255.255.255.0
This should wake the first computer up. If it does not, your system is most likely not compatible with Wake On LAN.
