220-1102 Question 149
Single answerSleep/suspendA user reports that a Windows 11 laptop loses several percent of battery overnight even though they select Sleep before putting it in a bag. In the morning, the laptop feels warm and resumes instantly when opened. The company wants the laptop to keep the session open but reduce battery drain and heat during long periods of inactivity, such as overnight travel. Which action should the technician recommend?
- A
Change the power action from Sleep to Hibernate for extended idle periods
- B
Disable the page file so RAM contents are not written during power transitions
- C
Configure a screen saver with a blank screen instead of using sleep states
- D
Turn off Fast Startup so the system uses less battery while sleeping
Show answer and explanation
Correct answer: A
Explanation
The best answer is to use Hibernate instead of Sleep for long periods of inactivity. Sleep/suspend keeps the session in RAM and uses a small amount of power, which can still drain the battery over many hours and may generate some heat in a bag. Hibernate writes the session to disk and powers the machine down, preserving the user's work while minimizing battery use. This aligns with standard Windows power-management best practices: use Sleep for short breaks and Hibernate for longer idle periods or when battery preservation is important. Microsoft documentation on Windows power options and hibernation behavior supports this distinction between Sleep and Hibernate.
- A. Correct.
Correct. Hibernate saves the current session to disk and powers the system off, which greatly reduces battery usage and heat compared with Sleep. The user can still resume their work session later, making this the best choice for overnight travel or other long idle periods. On Windows laptops, this is a standard recommendation when the device needs to preserve the session without continuing to draw meaningful power.
- B. Incorrect.
Incorrect. The page file is not the setting that controls whether the computer enters Sleep or Hibernate. Disabling the page file can reduce system stability and performance and does not solve overnight battery drain caused by the laptop remaining in a low-power sleep state. A common misconception is that hibernation simply uses the page file; Windows uses a dedicated hibernation file for Hibernate.
- C. Incorrect.
Incorrect. A screen saver only affects the display and does not place the system into a low-power suspend state. The laptop would continue running normally, which would typically use more battery than Sleep and far more than Hibernate. This distractor reflects confusion between display power management and actual system power states.
- D. Incorrect.
Incorrect. Fast Startup affects how Windows starts after a shutdown by using hibernation-related files for the kernel session, but it does not reduce battery drain while the laptop is in Sleep. Disabling Fast Startup may be useful for some boot or dual-boot troubleshooting cases, but it is not the appropriate fix for overnight battery loss and heat while suspended.
