Description: Follow this guide to replace a worn-out or dead...

Steps:

1. Slide the keyboard's power switch into the OFF position.
2. A red indicator should be visible beneath the switch.
3. Unplug all cables from your keyboard.
4. Lay your keyboard down with the feet facing up on a clean work surface.
5. If your work surface may scratch the keyboard, place a soft towel under it.

6. Heat an iOpener and lay it on the top left foot for one minute.
7. Alternatively, you can use a hair dryer on the Low heat setting to soften the adhesive.
8. If you're using a hair dryer, only heat the feet a few seconds at a time or you may warp the plastic.

9. The foot should come up without much force. If it feels stuck, apply more heat and try again.
10. Insert the point of a spudger under an end of the foot.
11. Push the spudger underneath the foot and lift until you can grip it with your fingers.
12. Peel the foot up and remove it.
13. Repeat the process to remove the remaining feet.
14. If you're replacing the battery, you only need to remove the feet along the top edge.

15. To install the feet during reassembly:
16. Use a pair of angled tweezers to peel up and remove all the plastic film from the foot recesses.
17. If you're installing new feet, remove them from their backing and firmly press them into place.
18. If you're reusing the feet, use a strip of double-sided tape to secure them in their recesses.

19. Plastic film may be covering the screws in the top edge foot recesses.
20. Use the pointed end of a spudger to poke through each film so you can access the screw underneath.

21. Use a Phillips screwdriver to remove the three 7.6 mm‑long screws securing the battery cover.

22. Plastic clips secure the battery cover.
23. Insert an opening pick between the top edge of the battery cover and keyboard.
24. Slide the pick along the top edge to release the clips.

25. Insert an opening pick between the bottom edge of battery cover and keyboard.
26. Slide the pick along the bottom edge to release the remaining clips.

27. Remove the battery cover.
28. During reassembly:
29. Place the battery cover onto the keyboard assembly so the screw holes line up with their posts.
30. Press down firmly along the battery cover to engage its clips.
31. You should feel and hear distinct "clicks" as the clips engage.

32. Use a pair of angled tweezers to firmly grip the battery connector and slide it straight out of its socket.
33. If you're having trouble, gently rock the connector side-to-side to help loosen it.
34. During reassembly:
35. Insert the connector into its socket so the side with raised plastic in the center is facing up.
36. Push on the edges of the connector with the flat end of a spudger until it's fully seated in the socket.

37. Pull the three battery cables out of their channel in the keyboard.
38. During reassembly, route all three cables through their channel so they're on top of each other.

39. Insert the flat end of a spudger underneath the right edge of the battery, opposite the cables.
40. Slide the spudger underneath the battery and gently lift to separate the adhesive securing it to the keyboard.
41. Make sure you push the spudger underneath the battery and not into it. Don't bend or deform the battery.
42. If the battery isn't separating, apply a few drops of isopropyl alcohol (>90%) to its edge and slightly tilt the keyboard. Wait one minute for the alcohol to soften the adhesive and try again.
43. Remove the battery.

44. To install a replacement battery:
45. Remove any bits of the old adhesive from the battery recess.
46. If your replacement battery doesn't come with tape pre-installed, apply double-sided tape to the battery recess (not directly to the battery).
47. If your replacement battery has adhesive pre-installed, remove the plastic liner.
