I think your mouse needs a vacation!!
Im no expert with the old mices but if the red LED light dies out like what happend to old arnold im pretty sure it cant reroute to an alternate power source.
you might just have to try drivers or buy a new mouse my friend.
The unknown future rolls toward us. I face it, for the first time, with a sense of hope. Because if frogman, a TiG-Member, can learn the value of hardware life, maybe we can too.
