For my home computing purposes, I use a Logitech MX700 cordless mouse. I have used a variety of Logitech devices over the years and never had any real trouble with them. Today, though, the MX700 failed to move the pointer around the screen. The first thing that comes to mind is connectivity, particularly as I use a Belkin OmniCube two port KVM switch. A quick test with my now retired MouseMan+ (it’s great when old kit backs you up: you wonder why you replaced it in the first place) confirmed that everything was OK on that front. Then, the thought struck me that the rechargeable NiMH batteries might have given up the ghost and were no longer recharging. I tried an old pair of NiCd‘s and everything seemed to work in spite of their not being fully charged. I will continue to use the MouseMan+ until they are fully charged and I will acquire some new NiMH rechargeables and monitor how everything goes.
