USB Mouse/Keyboard non-functional after complete shutdown and restart
Evening everyon. I completely shut down my Dell E520 yesterday and when I went to turn it back on today, the Microsoft wireless mouse and keyboard no longer work. I have also tried a wired (USB) mouse and keyboard and they do not work in any USB slot. There are 6 slots on the back and two on the front. I can remote destop to my pc and everything works fine on it, I just can use the keyboard and mouse on the system. Any ideas on how I can fix this problem?

If you reboot and press F2, F8 or F12 before Windows starts to load, does the keyboard work?
If it doesn't respond to any of the function keys before Windows loads, you can try this:
Power off and unplug
Press/hold power button on tower for ~15 sec
Open the case and remove the motherboard battery
Press/hold power button again for ~30 sec
Leave it unplugged like that for a couple of hours
Then reinstall the battery (right-side-up!) and see if it will work now with only mouse, monitor and keyboard attached.
