ID: 181851

Description: The easiest way to check whether the mouse...

Steps:

1. Turn off the mouse using the switch on the underside.
2. Remove the marked stickers/skates with tweezers or a scalpel.
3. If necessary, you can also pierce through the top sticker.

4. Remove the side buttons or the cover on the sides.
5. Remove the optional weight or the wireless charging puck.

6. Remove the 6 highlighted screws with a J00 Phillips driver bit.
7. Remove the Torx screw with the corresponding driver bit.

8. Lift the white tab on the ribbon cable socket. Then, you can carefully pull the cable out of the socket.
9. Disconnect these cable connections and set the lower case aside.
10. Remove the upper cover from the lower case. Note that there are cables on the back of the mouse.

11. Loosen the adhesive using either isopropyl alcohol or targeted heat.
12. When prying out the replacement battery, be careful not to damage it. For this, it is best to use an iFixit opening pick.
13. Try to insert the opening pick into the battery compartment from the front of the mouse.

14. From this point on, you will only need the J00 Phillips driver bit.
15. Remove the ten screws marked in red.

16. Now remove the screw under the battery compartment and set it aside separately.
17. Other screws will not fit into this thread.

18. The tabs on the top cover can get caught during removal. Pull the cover carefully toward the back and up, maneuvering it out with a slight pull.
19. Set the cover aside.

20. Rotate the mouse buttons out from the side.
21. Then turn the remaining mouse assembly over, remove the four marked screws on the mouse buttons, and set them aside.

22. Release the magnetic side button covers. Use the existing play to carefully maneuver the covers out.

23. Ideally, use a backward and upward motion as shown in the image to avoid getting caught on the DPI buttons.
24. Remove the four screws at the front of the mouse.
25. Remove the cover for the DPI buttons and the flywheel lock.

26. Fold the cover back, being careful not to kink or tear the ribbon cable.
27. Caution: The cable is attached to the PCB.
28. Remove the four screws marked in red on the mouse buttons.

29. Now, disconnect the socket of the corresponding mouse switch.

30. After replacing the mouse buttons, you can follow the guide in reverse to reassemble your device. If the battery and the skates remained intact, you are welcome to reuse them.
