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.
