220-1102 Question 148
Single answerPower plansA sales manager reports that her Windows 11 laptop battery is draining quickly during travel, but she still needs enough performance to use web-based CRM software and video conferencing. As the technician, you want to make the best single change using built-in Windows power management without manually adjusting multiple advanced settings. Which action should you take?
- A
Change the active power mode to Best power efficiency
- B
Switch the laptop to Airplane mode permanently
- C
Select the High performance power plan
- D
Disable hibernation from an elevated command prompt
Show answer and explanation
Correct answer: A
Explanation
The best answer is to change the active power mode to Best power efficiency. On modern Windows systems, especially Windows 11, built-in power settings are designed to balance performance and battery life without requiring the technician to manually tune processor, display, sleep, or disk settings individually. For mobile users, power-related troubleshooting and optimization should align with business requirements: preserve battery life while maintaining acceptable productivity performance. Microsoft documentation for Windows power and battery settings describes using power modes such as Best power efficiency, Balanced or Recommended, and Best performance to match workload needs. In this case, Best power efficiency is the most appropriate single change because it directly addresses battery drain and still allows normal business applications to function.
- A. Correct.
Correct. In Windows 11, changing the active power mode to Best power efficiency is the most appropriate built-in option when battery life is the priority but the user still needs the system to remain usable for normal business applications. This setting reduces power consumption while maintaining practical day-to-day functionality, making it the best single adjustment for this scenario.
- B. Incorrect.
Incorrect. Airplane mode can reduce power usage by disabling wireless radios, but setting it permanently would prevent the user from accessing web-based CRM tools and participating in video conferencing, both of which require network connectivity. A technician might choose this because it does save battery, but it does not meet the user's business needs.
- C. Incorrect.
Incorrect. High performance prioritizes system responsiveness over battery savings and typically increases power consumption. Someone might pick this because the user still needs performance, but the scenario specifically emphasizes extending battery life during travel while keeping adequate, not maximum, performance.
- D. Incorrect.
Incorrect. Disabling hibernation does not improve battery runtime during normal active use. In fact, hibernation is often useful on portable devices because it saves the session to disk and powers down the computer, preserving battery when the laptop is not in use. This distractor reflects confusion between startup behavior and active power-plan management.
