---

Remove Bottom Case

• Flip the MacBook Pro over and remove the bottom cover using the appropriate screwdriver.
• Carefully lift off the cover and set it aside.
• Observe the battery; note that one cell appears swollen, identifying it as the root issue.

Disconnect Trackpad Flex Cable

Disconnect Battery

Apply Isopropyl Alcohol

Optional: Unplug Trackpad Cable

• Set it aside; this step is optional but considered best practice during battery removal.

Prep Trackpad Flex for Reconnection

---

Reassemble Trackpad and Battery
