Removal

1. Place the enclosure in the repair tray with the USB-C connector facing the cutout.

   • Note: Three adhesive strips underneath the battery adhere it to the enclosure.

   • Warning: Don’t scrape or puncture the battery with the tweezers.

   • Important: Peel the adhesive tab completely from the battery before twisting it around the tweezers.

3. Keep the tweezers close and parallel to the battery. Twist the tab around the tweezers until you see the white adhesive strip on the tweezers (middle).

   • Important: Don’t pull the tweezers until the white adhesive is wrapped around them.

4. Pull the tweezers toward the USB-C connector and continue to twist the adhesive strip until you’ve removed the entire strip (right).

   • Caution: Don’t pull the adhesive strips against parts or screws.

   • Important: If the battery adhesive tab or strip breaks off and you can still see it, attempt to retrieve it with the tweezers. Wrap the tab or strip around the tweezers and repeat steps 3 and 4. If you can’t see the tab or strip, continue to step 5.

   

5. Use ESD-safe tweezers to grasp the bottom right battery adhesive tab. Gently peel the adhesive tab away from the battery.

   • Important

     • To avoid breaking the adhesive strip, don’t pull the adhesive straight up.
