@ repair pug, I did attempt to see if fixable, however there were multiple pieces of plastic, metal and loose circuit boards. Just bought a new one. Thank you for taking time to answer!

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.

You could try taking the mouse apart by locating all the screws, some may be under the mouse glider pads on bottom of mouse, and pop it open with a spudger prying tool.

Make sure both the LED connectors are seated correctly into the solder joints on

- and + on the PCB.

Mice are not durable. But you could have dialoged one of the boards. You could disassemble and see.

This just happened to my daughter’s mouse yesterday. I simply took the mouse apart (just one screw) - and snapped it back together - it works fine now. (I think the drop must have moved the roller off of its proper position). It took longer to find the right screw driver than to fix the problen (probably 2 minutes total once I had the screw driver)

Dropped mouse now red laser light not working

it worked- thank you!! [It - meaning light didn’t work - dislodged from hit to ground- I used plastic tools that I bought for fixing phone screen-so not to short anything out- I easily pushed a wire and plastic back to where it looked like it should go. ]

works great -with a lil tape also ? Thanks

i had purchased Logitech M221 silent mouse and realize that the Optic light is not working, but the mouse is working perfectly alright. Hence requested for a replacement and surprised to receive a new mouse again in the same condition. So wondering whether the Optical light will work or not on this model.
