Logitech Performance MX Disassembly

Peel off the three thin, plastic mouse feet on the bottom of the mouse. Make sure to carefully remove the adhesive along with the pad.

Use a thin flat object such as a flathead screwdriver to help remove if necessary.

Using a screwdriver, unscrew the four screws that were under the mouse feet.

Remove the battery from the mouse if not done already.

Gently pull the top of the mouse off from the base, making sure the wires and components are in place.

Carefully pull out the white enclosure from its port to safely take the top apart from the bottom.

Pull out the plastic pin in-between the scroll wheel and the battery enclosure and pull up on the scroll wheel base to remove.

Remove the 2 small springs underneath the scroll wheel base.

Unscrew the four screws holding the battery capsule onto the PCB.

Unplug the ribbon cable from the circuit board. Be careful to not remove the cable’s locking mechanism.

Unscrew the four screws to take out the black scroll wheel support in the center and the two black pads that lie on both sides of the support.

Pull the circuit board up to find the on and off switch. Take out the clear plastic bit that held the springs.

All parts should be visible to repair or for replacement.
