BE GENTLE!

Wiggle the front of the mouse and gently pull the top half towards the back.

SLIGHTLY LIFT THE TOP HALF ABOUT 5mm!

There is a ribbon cable and a power cable attached to the top and bottom.

SLOWLY! Wiggle the top ribbon cable out of its slot.

On the power cable, grip the plug itself and not the wires. Pull the power cable from the bottom.

YAY! You got them apart!
