Reason: ------- The problem is caused by the Rechargeable battery provided by Microsoft. It`s slightly longer than normal rechargeable ones and pushes the +voltage plate, forcing it to loose contact with the PCB. Solution: --------- Replace the battery with other rechargeable one (make sure its no more than 1000mAh and it will be charged normally). I used Duracell Rechargeable 1000mAh battery, works like a charm. I prefer to use different battery and not to modified the mice, because the battery may loose the contact with the pads when it's in charging process. Ni-MH batteries doesn't like to be charged partly, they need full charge and full discharge. The logic inside the Mice is engineered to stop the charging process when it needs (Full Charged) and to start it when the battery voltage is not lower than 0.9V (Full Discharged). Otherwise they suffer from memory effect and they loses the charge holding abilities. Microsoft Wireless Mobile Mouse 8000 LED status / states: --------------------------------------------------------- Red Solid: Internal PCB or Logic error. Red Flashing: Alert state - No battery detected, mice working on USB cable charge lead. Green Flashing: Charging state - Battery charging / Working on USB cable charge lead. Green Solid: Normal State - Battery full charged / operating on Battery. Kind Regards Gyunay Anach IT-Solve Technician Problem:

I bought this one because I broke my ms 6000, wich had two non rechargeable batteries and it was lasting mor than a year! My solution for the 7000 is to use rechargeable batteries in a universal charger and throw the 7000 craddle in the garbage! nothing works for mine.

I contacted Microsoft about it and they sent me a new set and did not ask for the old one to be returned. I now have 2 working for the price of one, every now and then I win.

I don't have one of these, but it does sound like the problem is with the mouse. Do you know anyone else with the same keyboard and mouse combo? If so, you can try pairing your mouse with their USB dongle and vice versa to determine if the problem is the mouse or the dongle. @Jim: Hmm.

I have a Microsoft Natural Wireless Laser Mouse 7000. It is slightly different to the one described in this thread, but there is not a discussion/thread specific to the issue I have. The Keyboard and Mouse are paired to a USB dongle. They use regular AAA batteries. I can click the reset button underneath the mouse, the green light on top comes on for a few seconds and then fades off. This is how it should be. The mouse is not working. The receiving USB stick has a tiny led that flickers when either the keyboard or mouse is operated. It's a tiny light and you have to look carefully to see it. It flickers for the keyboard but not for the mouse anymore. I have tried all the trouble shooter guide steps and everything MS recommends: Put the stick in other USB sockets, reinstall, etc. Nothing. The mouse throbs the green light when it moves, which I'm pretty sure it didn't do before hand. So, good batteries, good keyboard, non-functioning mouse. Thanks.

I used a cotton stick to clean them and voila its working again! Another reason for this issue is rust that gets on the two charger metal plates that come into touch with the mouse.
