Steps:

1. Before you begin, shut down your laptop and unplug it.
2. Close the screen and lay your laptop down with the rear case facing up to access the four rubber feet.

3. Insert an opening pick between the rear case and the rubber foot.
4. Pry up with the pick and dislodge the foot from the rear case.
5. Use tweezers or your fingers to remove the rubber foot.
6. Repeat this process on the remaining rubber feet.
7. There are two types of rubber feet for this laptop. During reassembly, make sure the top feet say "M4" and the bottom feet say "M1".
8. To reinstall a rubber foot, align it over the recess and push down until it's secured.

9. Use a Phillips screwdriver to remove the four 4.5 mm screws securing the rear case.
10. Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

11. Apply a suction handle to the middle of the rear case's bottom edge, as close to the edge as possible.
12. Pull up on the handle with a strong, steady force to create a small gap between the rear case and the frame.
13. This may take significant force and multiple tries.
14. Insert an opening pick into the gap you created.

15. Slide the opening pick along the bottom edge to release the clips securing the rear case.
16. Continue sliding the pick along the perimeter of the laptop until all the clips securing the rear case have been released.

17. Lift the rear case up and away from the laptop and remove it.
18. During reassembly, this is a good point to power on your laptop and test all functions before sealing it up. Be sure to power your laptop back down before you continue working.

19. Use tweezers or your fingers to peel up and remove the tape covering the battery connector.
20. Set the tape aside. You'll reuse it during reassembly.

21. Insert the flat end of a spudger under the battery cables, as close to the connector as possible.
22. Gently pry up and disconnect the battery connector from its socket.

23. Use the pointed end up a spudger to pry up the locking flap on the left fan cable's ZIF connector.
24. During reassembly, make sure that all seven cables are connected to the daughterboard.

25. Grip the left fan cable's pull tab with tweezers and gently pull the cable out of its socket.

26. Use the flat end of spudger to pry up and disconnect both of the interconnect cable's press connectors from the daughterboard.
27. To re-attach press connectors like these, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.

28. Use the pointed end of a spudger to pry up and disconnect the bottom left speaker's connector from the daughterboard.

29. Insert the pointed end of a spudger under the black antenna cable and slide it as close to the connector as possible.
30. Gently lift straight up to disconnect the antenna.
31. The connector is very delicate and can easily break if a quick or strong force is applied.
32. Repeat the disconnection procedure on the white antenna cable.
33. To reattach coaxial connectors like these, align the connector over its socket and press down with the flat end of a spudger. The connector should snap into place. This can be tricky and may take a few tries.

34. Use tweezers or your fingers to lift the black and white antenna cables out of their clips on the daughterboard.

35. Use the pointed end of a spudger to pry up the locking flap on the backlight cable's connector.

36. Grip the backlight cable's pull tab with tweezers and gently pull the cable out of its socket.

37. Use a spudger to pry up the locking flap on the left display cable's ZIF connector.

38. Grip the left display cable's pull tab with tweezers or your fingers and gently pull the cable out of its socket.

39. Use the pointed end of a spudger to pry up and disconnect the fingerprint sensor's press connector.

40. Use a Phillips screwdriver to remove the five 3.5 mm screws securing the daughterboard.

41. Lift the right side of the daughterboard up and pull towards the center of the laptop to remove it.
42. During reassembly:
43. Move all cables that connect to the daughterboard (display, fingerprint, interconnect, speaker, backlight, and antennas) out of the way so they don't get stuck under the daughterboard when it's reinserted.
44. Reinsert the daughterboard at a downward angle to position the headphone jack, USB-C port, and memory slot back into their recesses.
45. Before securing the daughterboard, make sure the alignment pins on the frame are in their cutouts on the daughterboard.
