Show answer and explanation
Correct answers: A, B, C, F
Explanation
To extend the battery life of a laptop, it is important to prioritize power-saving strategies, such as enabling power-saving modes, reducing screen brightness, disabling unused hardware like the Wi-Fi adapter, and lowering CPU performance settings. Avoid high-performance power modes or prolonged inactivity settings, as these can lead to increased battery drain.
- A. Correct.
Enabling the laptop's power-saving mode optimizes the system's settings to reduce power consumption, making it an effective way to extend battery life.
- B. Correct.
Reducing screen brightness is a simple and effective way to conserve power, as the display is one of the primary consumers of battery energy.
- C. Correct.
Disabling the Wi-Fi adapter when not in use prevents unnecessary power consumption by the wireless network interface.
- D. Incorrect.
Enabling the high-performance power plan prioritizes performance over energy efficiency, which will drain the battery faster.
- E. Incorrect.
Configuring the display to turn off after one hour of inactivity is not ideal for saving power; setting a shorter inactivity period would be more effective.
- F. Correct.
Lowering the CPU performance settings reduces the processor's power consumption, which helps extend battery life.
