Solved Dropped Mouse Now Red Laser Light Not Working Logitech M170 Wireless Mouse
Chosen Solution Logitech Wireless w/ Keyboard (receiver and keyboard work fine) mouse dropped now redlight does not turn on. M-R0013 new battery - tested in remote works fine - I did take apart, several pieces broken. Just replaced it. Thanks Sounds like the Optical light came off the PCB (Printed Chip on Board) from my research this is an ongoing issue with the mouse after being dropped. -My best bet would be that the light came off the solder joints with - or + connections and causing it not to light and unable to reflect a light to the sensor....
