>when wireless keyboard or mouse runs out of battery, you need to re-establish the bluetooth connection in order for them to be functional again. To do so, you need to press the connect button on the keyboard and the USB dongle connected to the computer at the same time for about 8-10 seconds to establish connection. After that, you can try typing again. Same thing applies to wireless mouse.
I checked with someone from the Tech Support Department in my company and suggested I press the connect buttons. I also changed the batteries in my wireless keyboard. I pressed the connect buttons on the receiver, mouse and keyboard. After all this the mouse started working again.
there are three reset buttons one on the bottom of the mouse and one on your keyboard's backside and there is a reset button on the receiver that plugs into the USB press all at once untill lights flash and try to get it to connect again.

1- use "Reset" (in you case it might be "Connect") buttons on your keyboard's backsid and also on receiver.
2-use "Reset" (in you case it might be "Connect") buttons on your mous's backside and also on receiver.
If all the above did not work do open the keyboard it self and make sure the areal (a wire beside the frame going all around the edge of the keyboard inside) is connected to the circuit board if not reconnect.
Turn the mouse over and find the small rest/connect button
on the bottom of the mouse and press it. This should connect the mouse to
the receiver and work properly. If not, try pressing the receiver button
and then press the button on the mouse. This should be done whenever you
change batteries or glitch. Hope this helps you. Bud

I have been fighting this same problem for about 5 months.
I have the Wireless Optical Desktop 3.0 (Wireless Comfort Keyboard & Wireless Optical Mouse 2.0). Three or four times a week it stops working at random intervals. The driver DLLs simply disappear. I can see this by going to Control Panel -> Keyboard Properties -> Hardware -> Properties -> Driver -> Driver Details. The two dll files are there when it works and the dll files are gone when it stops, gone, no drivers at all. An old PS2 will still work in a pinch.
I wonder if the problem may be caused by my Windows Live OneCare or by a Windows Update that keeps reinstalling itself and failing. Alternatively, could it be that some malware is trying to gain control of the PC?
Reinstalling the software & rebooting fixes the problem --for about a day.
