Hi,
On an XPS One 2710 with Win 8 Pro, while I can get the PC to sleep using the settings>power>sleep button, I can't wake the computer using the Dell wireless mouse or Dell wireless keyboard. I've verified that the mouse is enabled in its power management device settings to wake the computer (the keyboard settings don't have a power management setting available to enable). I've turned off hybrid sleep. So, the device (at least the mouse) should wake the computer, but it doesn't. The only way to wake the computer, so far, is using the power button.
However, if I use a wired USB mouse instead of the wireless mouse, the wired mouse will wake the computer from sleep when I move it, which is correct.
Any suggestions to fix this would be appreciated.
