Not detecting keyboard until I replug ...

Logitech G15 keyboard
October 16, 2009 at 11:54:29
Specs: Microsoft Windows 7 Ultimate, 3 GHz / 6142 MB
Sometimes when I boot my computer up, or leave my computer and come back to find it at the standby login screen -- the keyboard will not have power and and i cant type my password in until i go behind the tower and replug in the keyboard. My drivers for the keyboard are up to date!

The keyboard is a USB device (on motherboard). This also sometimes happens to my mouse.

Any ideas how I can fix this?

(These instructions work on vista, windows 7 may have
slightly different names)

click Start, Run, then type


and press enter. This should bring up the Device Manager
(possibly after a UAC prompt).

Expand 'Keyboards', right-click on the keyboard item (HID
Keyboard, USB keyboard, etc.) and click properties. click
the Power Management tab, and list all the items there and if
it's checked, unchecked, or grayed out.

Do the same thing by Expanding 'Mice and other pointing
devices', right-clicking on HID Mouse, USB Mouse, etc.,
going to Power Mangement tab, and doing the same thing.

Under Device Manager > Keyboards

I had two "HID-compliant mouse" listings...

One with power management, one without... I uninstalled the one without.

On the power management tab of both the mouse and the keyboard listings -- "allow this device to wake the computer" is checked and "allow the computer to turn off this device to save power" is unchecked.

these settings were already in place... but ill see if removing the second keyboard device helps.

ill post the results

This is a desktop, right? Turn off Standby & do NOT use Hibernate.
