Hi,
Well I have 3 5000 mice one of which failed after 1 1/2 years and the other two are
4+ and 2 1/2+ years old with constant use (and abuse). My thinking is there must
have been a bad productioon run or two, or possibly part of some several production
runs are failing.
If you have one that does not work properly exercise the warranty if it is still in place.
If needed check your mouse for warranty.

Wireless Mouse 5000 - 3 year Warranty I believe is the correct one
Microsoft Hardware Warranty Info.
http://www.microsoft.com/hardware/Warranties.mspx
The mouse comes with 90 tech support from day of 1st incident which would start when
you contact Microsoft at the below number.
If the mouse is defective check with the seller or Microsoft.
MS Hardware Support and Warranty Claims
Tech Support 1-800-936-5700 for MS Hardware.
Hope this helps.
