Removal
Use ESD-safe tweezers to peel back the polyester film from both ends of the trackpad connector cowling to access the two 3IP screws.
Important: Don’t remove the polyester film from the cowling.
Use the blue torque driver and 3IP 44mm half-moon bit to remove the two 3IP screws (923-08925) from the trackpad connector cowling.
Pinch the trackpad flex cable cowling (1) and lift it off the connector (2).
Use the 10–34 Ncm adjustable torque driver and 3IP bit to remove the four 3IP screws (923-10475) from the sides of the battery tray.
Use the adjustable torque driver and 3IP 25mm bit to remove the two 3IP screws (923-08991) from the middle of the battery tray.
Use ESD-safe tweezers to grasp the first battery adhesive tab (1). Gently peel the adhesive tab away from the top case.
Use ESD-safe tweezers to grasp the second battery adhesive tab (2). Gently peel the adhesive tab away from the top case.
Pull both battery adhesive tabs to peel them away from the battery tray and top case (3).
Important: While grasping the two battery adhesive tabs, pull the adhesive strip past the edge of the top case at a slight upward angle until you’ve removed the entire adhesive strip (4). Don’t let the adhesive strips touch the edge of the top case.
Repeat steps 6 through 8 to remove the remaining three battery adhesive strips (2–4). Then continue to step 10.
- Warning:
If a tab or adhesive strip breaks off and you can still see it, remove any other remaining adhesive strips. Then attempt to retrieve the broken strip with ESD-safe tweezers.
If you can't see a tab or an adhesive strip breaks off and can't be retrieved, don't forcibly pry the battery. Stop the repair and refer to Battery Safety. A replacement top case and battery are needed to complete the repair.
Hold the battery cover by the edges and lift it off the top case.
Gently peel the trackpad flex cable off the top case (1, 2).
Caution: Don’t fold or crease the flex cable (3).
Gently lift the battery and support it from underneath (1). Grasp the battery flex cable and slide it out from under the logic board (2) as you lift the battery out of the top case.
- Caution: Don't touch the middle of the battery (shown in red). Handle the battery by the battery tray only.
- Warning: Don't remove the battery from the battery tray.
Reassembly
Use ethanol wipes or IPA wipes to clean any battery adhesive residue from the top case.
Fold the tabs on each battery adhesive 90 degrees at the perforated line as shown. Then remove the adhesive backing.
Align the battery adhesive over the corners of the top case as shown.
Press the battery adhesive strips onto the top case as shown.
Support the battery from underneath as you lower it into the top case. Slide the battery flex cable under the logic board (1) while aligning the connector on the end of the flex cable with the connector on the logic board (2).
- Caution: Don't touch the middle of the battery (shown in red). Handle the battery by the battery tray only.
Position the battery flex cable alignment tool pins next to the screw holes as shown (1).
Lay the tool flat as you insert the alignment pins into the screw holes (2).
