As it would be obvious to most, this is a hardware problem with this product. In my case the issue was with a Modern Mouse and the fix would be a bit different for the surface mouse. I do not want to try it on the surface mouse as it is working fine and I am afraid to ruin it.
So, here is the solution:
- Snap open the top shell
- Remove the 4 T5 screws
- Remove the inner shell
- Observe that the wheel is moving freely on the inner spindle
- Move the wheel to one side so that the spindle is exposed.
- Put half-a-drop of superglue. Too much will ruin everything.
- Slip back the wheel into place
- Put back the inner cover
- Wait for a few hours to let it dry
- Snap back the outer shell
- Test it out... mine is working line original
