Windows 7: device power managment not available

17 Nov 2009   #1

Windows 7
device power managment not available

My keyboard is shut off when my system resumes from sleep and I have to unplug it and plug it back in to get it to work again. i was hoping the "allow this device to wake the computer" option would fix it, I can't access the "allow device to wake computer" option for my usb hubs in device manager because they are grayed out.

The option "Change settings that are currently unavailable"
does not appear in the advanced power settings. I have admin status and have tried logging in as admin but the option still does not appear.

I have enabled the option to allow usb devices to wake the computer in Bios, but it makes no difference. My network adapter is the only device which allows me to select the power option.

Any advise?
