    Hi, has anyone been able to use USB wake from sleep on this machine? I ordered the Dell KM714 wireless combo (made by Logitech), and the "Power Management" tab is not available in the mouse or kb properties. I looked thru the BIOS and don't see any way to enable this either.

    I am using this system with an external monitor, and I don't want to have to open the lid every time and use the power button.

    Thanks for your help!

    Problem solved... sort of.

    After a lot of research and some trial and error, with no help from Dell I might add, I fond a workaround.

    It seems Intel Rapid Start is preventing USB wake from sleep. In the BIOS, after disabling Rapid Start, the option to use USB wake suddenly appears and can be enabled. So it's a trade-off: I can either use USB wake or Intel Rapid Start.

    I forwarded this solution to Dell and hopefully it will be addressed in a BIOS update.
