Follow safe disassembly, tool, and ESD practices for A+
Short answer
Before opening a device, power it off, remove external power, remove a removable battery if present, and consult the service manual. Use ESD protection when practicable. Use the correct precision drivers, nonmetal opening tools to separate clips and adhesive, and a parts tray or labeled containers to track screws. Avoid aggressive metal prying that can damage connectors or scratch components.
Why it appears on the exam
- Given a short scenario, choose the best first step: power off and consult the service manual before attempting to remove a glued display. - Identify the correct tool choice to release a clip without damaging a flex cable.
