HP Notebook PCs - Managing Power Options (Windows 8)

This document pertains to HP and Compaq notebook computers and tablets with Windows 8.
 note:
If you are not using the latest version of Windows 8, some graphics and information in this document may vary. You can get the latest version from the Microsoft Store.
This document provides information about working with Windows power plans. In addition, this document provides methods for shutting down your computer, using various power modes, and troubleshooting power issues.
Working with Windows 8 power plans
A power plan is a collection of hardware and system settings that manage how your computer uses power. You can use power plans to reduce the amount of power your computer uses, maximize performance, or balance the two. The power management options available on your computer might be slightly different than those shown in this document.
Windows provides the following default plans to help you manage your power usage:
Power Plan
Description
Balanced (recommended)
Automatically balances performance with energy consumption.
Power saver
Saves power by reducing system performance.
High performance
Maximizes system performance and responsiveness.
Shutting down your computer
This section provides three different procedures for shutting down your computer.
Using Sleep mode
By default, when you select the Sleep option or press the Power button, Windows enters sleep mode. This saves the current work session in memory and puts the computer in a low-power state. Any opened programs or documents stay open allowing you to quickly resume your work when you return to the computer.
Using Hibernate mode
Hibernation is a power-saving state that saves open documents and programs to the hard disk and then turns off the computer. When you press the Power button to turn the computer back on, the computer quickly comes out of hibernation and restores the open programs and documents that were saved.
Enabling Away mode when sharing media files
Away mode enables your computer to continue performing tasks, such as recording television programs or sharing video and music, even if you walk away from the computer. Specifically, when the computer is in Away mode, the following occurs:
  • The computer can still perform tasks such as recording scheduled TV programs or stream video and music files to a remote location.
  • The display is turned off.
  • The audio is muted.
  • The computer is operational, but in a reduced-power setting.
  • The computer fan runs.
  • The desktop displays almost instantly when you press the Sleep button on the remote control.
To enable Away mode, complete the following steps:
  1. At the Start screen, type power options to open the Search charm. Select Power Options in the Search results.

  2. In the Choose or customize a power plan window, click Change plan settings next to the plan that you wish to change.
  3. In the Change settings for the plan window, click Change advanced power settings.
  4. Click the plus sign (+) next to Multimedia settings to expand the list.
  5. Click the plus sign (+) next to When sharing media.
  6. Depending on whether you wish to use Away mode when the computer is on battery or plugged in, or both, select Allow the computer to enter Away Mode in the On battery or Plugged in drop-down boxes.
     note:
    If Allow the computer to enter Away Mode is not available, your computer does not support this feature.
