The mouse model MG-0982 came with the computer, which I bought in 2012. It seems to have trouble connecting to the computer, but it has fresh batteries. I checked the wireless dongle, RG 0983. I removed and replaced it. It lights up when first installed, but then the light goes off. I have rebooted three times since removing and replacing the dongle. Best I can tell, the keyboard is also not making contact. However, I was able to scan from my wireless printer to the computer. New dongle needed? Driver issues? HELP!
Photoray002--Thank you. I removed and replaced the dongle a few times. I also found thta the mouse was unexpectedly turning off. I think it might have been a problem with the batteries not seating properly. After a few tewaks of the battery contacts, and a couple of new batteries, the device started working again.
So, we are good to go for now, but if I do have further problems. I have your excellent advice to follow.
