  1. click my computer, on your desktop
    click control panel, it's on the left hand side of my computer window
    click the "system" icon, a window will open that says system properties
    click the hardware tab
    click the device manager bar
    when the device manager window opens, scroll down, find universal serial bus controllers
    double click universal serial bus controllers, it's on this list
    now you will see a list, find USB root hub on the list
    double click the first USB hub on the list
    when the USB hub properties window opens, click the power management tab at the top of the window
    now you will see a box that says: "allow computer to turn off this device to save power"
    Un-check that box, click OK
    Now double click the second USB hub on the USB Hub Properties list, click the power management tab, un-check the power saver box just as above, and click OK
    Now repeat that same procedure for all the other USB hubs on the list, un-check the power saver box in each USB hub, until you have done all the USB hubs on the list. There may be several, you must do each, one at a time.
    Now close all your windows and restart the computer.
    Now the mouse should stay on.
    The computer was turning off the mouse (keyboard) to save power.

    I have (had) an intermittent problem where the KB on my new Acer Aspire V7 (Win 8.1) would not work - with the exception of the Fn+F9 and the Vol and Brightness controls. After a LOT of searching -- others led me to the problem and the fix:

    The PROBLEM: Avast ASWKBD.sys is buggy. Search for more information.( It may also be other entries in the upperdrivers key - see below.)

    The FIX: Use regedit.exe to search for "aswKbd" (in the upperdrivers key) and delete the string "aswKbd" ONLY and nothing else!!! After that, use Unlocker to rename aswkbd.sys in the windows/system folder to aswkbd.old. Reboot. Problem solved.
