A technician needs to replace the battery in a modern ultrabook. The battery is glued to the chassis rather than secured with screws. What is the PRIMARY safety concern the technician must address during removal?
- AVoiding the manufacturer's warranty
- BPuncturing the battery causing fire or chemical exposure
- CElectrostatic discharge damaging the CPU
- DOverheating the adjacent RAM modules
Show answer & explanationAnswer & explanation
Correct answer: B. Puncturing the battery causing fire or chemical exposure
Glued-in lithium-ion batteries require careful prying with plastic tools to avoid puncturing the cell, which can cause a fire, chemical burns, or toxic fume release. This is a critical safety hazard beyond typical ESD or warranty concerns.
Why the other options are wrong
- A. Warranty concerns are a business issue, not a physical safety hazard during removal.
- C. ESD is a general concern for electronics but not the primary risk with glued batteries.
- D. RAM overheating is not a specific risk tied to battery removal technique.
Glued Battery Removal Safety
Lithium-ion batteries adhered with adhesive require careful, gentle prying using plastic tools to avoid puncturing the cell and causing fire or chemical hazards.
- Use plastic spudgers, never metal tools
- Punctured lithium cells can ignite or swell rapidly
- Adhesive removal solvents/heat can help loosen safely
Memory trick: Pry gently — a punctured battery can turn into a pocket fire.
