Windows 7: Wake-on-Lan (WOL) does not fully wake PC... Screen dark

Wake-on-Lan (WOL) does not fully wake PC... Screen dark

I'm sure this issue has been discussed and hopefully resolved - but I've been unable to find the right search string to get me to the solution.

When I send a magic packet to one of my PCs at home, the PC responds by powering up. The monitor goes from "no signal" to black screen. The power light on the PC goes from blinking to solid - and the PC fans all come alive. Absolutely no doubt that the packet was received and the PC responded.

However, using VNC or teamviewer, the PC continues to register as 'off line'. At this point, if I bump the mouse, or hit any key, the screen goes from black to full desktop - instantly. It's as though the PC needs just one more push to completely wake.

This, of course, makes any WOL remote access completely useless, as no one is home to bump the mouse.

My other two PCs wake completely when the same packet is sent to them. I've configured everything exactly the same. The only difference is in the BIOS setting. The PCs that work have a WOL "enable" option, where the one that doesn't work only has a Wake on Ring "enable" option.

I'm at a loss, and really hope others have already paved the way to a solution.

All PCs running W7U/64, same LAN/subnet, all have windows firewall off, no software firewalls, and this issue happens whether sent from local LAN or external.

TIA - E.
