  • 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.

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!
