Hi Rodger. It will depend on the manufacturer of your cordless mouse. Some like Logitech let you re-pair the mouse with a new dongle or vice versa, however as a general rule, the dongle as supplied with the mouse is the one you must use for that particular mouse. I have an Anker desktop combo, and recently I managed to loose my dongle as the things are so tiny these days. I had no option but to buy a new kit as the dongles are paired at the factory and you can’t get replacements. All the best, Ibrahim.

Yesterday being a little heavy handed I bent an internal mechanism of a spare slot with a pen drive. Now my mouse won’t work. I’ve tried it in all 6 working slots and 4 accessible ones on the tower all to no avail. I have another unused cordless mouse and that will not work either. I’ve changed the Batteries which register as full on a tester and the red light under the mouse is on. However I pinched the Guvnor's corded mouse off of her laptop and it works just fine but the lord irritates the hell out of me. As the unused cordless mouse won’t work there is no point in buying another so the solution has to be elsewhere. Is it possible I need to download drivers for example or maybe go into Devices Manager to get the system to recognised the mouse. Any help will be much appreciated with thanks. Roger
