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 devmgmt.msc 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. Power Schemes > System Standby = NEVER Standby & Hibernate Issues in XP
