Windows Advanced Power Options Explained


  • Dim Display After vs. Turn Off Display After. For maximum battery life conservation, consider skipping the Dim setting and set the screen to turn off completely after 10 minutes. It should take less than a second to bring it back when you’re ready to use your notebook.
  • Display Brightness. The backlight in a notebook’s LCD is the biggest power hog of any component. Experienced road warriors know to turn the brightness down to make a battery last longer, but how low is low enough? When we perform the LAPTOP Battery Test to determine a notebook’s longevity, we set brightness at 40 percent, which is a good balance between conservation and visibility. Depending on the model, a screen may be legible at as low as 20 percent. Play around with the settings to find a comfortable brightness, then set it as the default.
  • Dimmed Display Brightness. Determines how far down to take the brightness if you use the Dim Display After setting. We recommend skipping this setting.

Multimedia Settings

  • When Sharing Media. When your notebook is sharing music, video, or other media via a program such as Windows Media Center, Windows doesn’t automatically count the streaming as activity if you aren’t actually using the laptop, and may read it as being idle. When plugged in, set the notebook to Prevent idling to sleep to keep the stream going. To save a little energy, choose Allow the computer to enter Away mode, which makes a notebook appear to be sleeping even though it’s not. As this is not a true sleep state, and won’t conserve much energy, don’t choose this setting when running on the battery. Instead, choose Allow the computer to sleep.
  • When Playing Video: Optimize Video Quality, Balanced, and Optimize Power Savings. Balanced is a good choice if you need your notebook to keep you entertained on a long commute. When plugged in, you’ll want the best video quality unless you’re trying to conserve watts. Should you need to watch video but also save battery life just as badly, choose Optimize Power Savings.
