Safety Precautions
- • Always disconnect power and discharge the battery before beginning any repair.
- • Use an anti-static wrist strap (ESD) to prevent electrostatic damage to components.
- • Keep screws organized by step — magnetic project mats are highly recommended.
- • Never force connectors. Use a spudger to gently lift ZIF, FPC, and board-to-board connectors.
- • If your Mac has a swollen battery, do not attempt removal yourself — contact a professional.
