HP Desktop PCs - Managing Power Options (Windows 8)

This document pertains to HP and Compaq desktop computers using Windows 8.

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 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.

Windows provides the following default plans to help you manage your power usage:
