100-140 Question 269
Single answerA user reports that their laptop battery drains quickly, even when in sleep mode. Upon investigation, you find that certain devices are still consuming power while the laptop is asleep. Which power management option should you configure to minimize power consumption during sleep?
- A
Disable Wake-on-LAN in the BIOS or UEFI settings
- B
Enable high-performance mode in the power plan settings
- C
Reduce the screen brightness to the minimum level
- D
Enable Hibernate mode instead of Sleep mode
Show answer and explanation
Correct answer: A
Explanation
Disabling Wake-on-LAN is a key power management configuration when aiming to minimize power consumption during sleep mode. This setting prevents devices from keeping certain components active, which can drain the battery even when the system appears to be idle.
- A. Correct.
Wake-on-LAN allows the computer to be woken up remotely, which can cause power drain even in sleep mode. Disabling this feature reduces unnecessary power consumption.
- B. Incorrect.
High-performance mode prioritizes performance over power efficiency, leading to increased power consumption rather than reducing it.
- C. Incorrect.
Reducing screen brightness only affects power usage while the laptop is awake and does not impact power consumption during sleep.
- D. Incorrect.
Hibernate mode can save more power compared to sleep, but the question specifically asks for a configuration to minimize power consumption during sleep, not to replace it with another mode.
