220-1202 Practice Question: A user complains that their laptop battery drains…
A user complains that their laptop battery drains quickly and the device gets very hot. The battery is a lithium-ion type and is three years old. What is the most environmentally responsible recommendation?
⚠ Common exam trap
A common mix-up: candidates choose Option B (remove battery and run on AC) thinking it solves the heat issue, but they overlook that the old battery still needs proper disposal and that the laptop's heat could stem from other factors like dust or failing thermal paste.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replace the battery with a compatible model and recycle the old battery at a certified e-waste facility.
It directly addresses the user's complaint (battery degradation causing heat and poor runtime) while ensuring responsible disposal of the hazardous lithium-ion battery. Recycling at a certified e-waste facility prevents toxic materials from entering landfills and allows recovery of valuable metals, aligning with environmental best practices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace the entire laptop with a new Energy Star model.
Why it's wrong here
Replacing an entire laptop due to a single component failure, such as a battery, is an economically unsound and environmentally irresponsible practice. This action generates unnecessary electronic waste (e-waste) and contributes to resource depletion, rather than promoting the repair and reuse principles advocated in sustainable IT practices. A more cost-effective and eco-friendly solution involves component-level replacement.
- ✗
Remove the battery and run the laptop only on AC power.
Why it's wrong here
Removing the battery and operating the laptop solely on AC power eliminates the device's primary benefit of portability, rendering it a less versatile desktop replacement. Furthermore, this approach fails to address the critical issue of proper disposal for the old, potentially hazardous battery, which still requires recycling at a certified facility. It also wastes any remaining, albeit diminished, useful life the battery might have had for brief unplugged use.
- ✓
Replace the battery with a compatible model and recycle the old battery at a certified e-waste facility.
Why this is correct
Replacing the depleted battery with a new, compatible model is the most appropriate and sustainable solution. This action restores the laptop's full functionality and portability, significantly extending its useful lifespan while being more cost-effective than purchasing a new device. Concurrently, recycling the old battery at a certified e-waste facility ensures hazardous materials are handled safely, preventing environmental contamination and promoting resource recovery.
- ✗
Continue using the laptop until the battery fails completely.
Why it's wrong here
Continuing to use a laptop with a rapidly draining battery is ill-advised due to potential safety hazards. A failing lithium-ion battery can swell, leading to physical damage to the device and posing a significant risk of thermal runaway, fire, or explosion. Ignoring these warning signs is not only unsafe for the user but also environmentally irresponsible, as it delays proper hazardous waste disposal.
