The scroll wheel on this gaming mouse has holes in it that the optical sensor uses to detect when the wheel is turning. If dirt or other foreign material covers the sensor or the holes, the scroll wheel will stop working or may only work intermittently. This guide will demonstrate how to open the mouse and take the wheel assembly apart for cleaning.

  1. Use a thin blade to peel up the corners and remove the mouse feet. They re-adhere very well, so be careful to not damage them or get the sticky side dirty. Unscrew the three screws that are now visible. Gently pull apart the top and bottom halves of the mouse. They will be connected by a wire.

  4. Optional: If there is any material near the base of the mouse, under the scroll wheel, the sensor chip can be unscrewed and removed. Use a gas duster to remove any remaining dust from inside the mouse.

My mouse went from scrolling just fine to nothing overnight. This helped a lot, but sadly its still not 100%. :(

Worked like a charm. Thanks. I really like this mouse and didn't want to have to get used to another one.

Fantastic!!! I've been really reluctant to replace my MX510 mouse -- your teardown of this one (which the internals appear to be identical anyway) was perfect!

My mouse is running like brand new again!
