Windows 7 | Specifies whether Windows allows applications to temporarily prevent the display from automatically reducing brightness or turning off to save power. |
| Default display brightness |
10% - 100%, Don't change |

| Dim display | After x minutes, After x hours, Never After 3 minutes |
Vista, Windows 7 |
The period of inactivity before the display brightness is automatically reduced. This setting applies only to portable computers that support Windows control of the brightness level of an integrated display device. |
| Dim display brightness |
10% - 100%, Don't change |
Windows 7 | Reduced display brightness level after the dim idle timeout has been reached. This setting applies only to portable computers that support Windows control of the brightness level of an integrated display device. |
| Allow hybrid sleep | Disable, Enable, Don't change |
Vista, Windows 7 |
A combination of Hibernate and Standby, where the system state is stored both in RAM and on disk, in an effort to protect the state data should power be unexpectedly cut to the workstation; of primary use for desktops. Can be problematic with legacy hardware and/or device drivers. |
| Automatically wake for tasks | Disable, Enable, Don't change |
Windows 7 | Specifies whether the system uses the systemwide wake-on-timer capability. The system can automatically use wake-on-timer on capable hardware to perform scheduled tasks. For example, the system might wake automatically to install updates. |

|
Lid closed action |
Don't change, Do nothing, Shutdown, Sleep, Hibernate |
Vista, Windows 7 | Specifies the action that Windows takes when a user closes the lid on a laptop. If set to Sleep, it is still possible that a laptop can reawaken while in transit (while in a computer bag, for example), leaving either less or no battery power available when reaching the destination. If set to Hibernate, an end-user can shut their laptop lid, put the laptop in their bag, and upon returning home from work, start up from where they left off. |
| Power button action |
Don't change, Do nothing, Shutdown, Sleep, Hibernate |
Vista, Windows 7 | The action that Windows takes when an end user presses the Power button |
| Power button force shutdown | Disable, Enable, Don't change | Windows 7 |

| Desktop slideshow | Disable, Enable, Don't change | Windows 7 | Configures the behavior of the desktop background slideshow. |
| Media sharing |
Don't change, Allow idle sleep, Allow away mode, Prevent idle sleep |
Vista, Windows 7 | Away Mode was designed to handle media sharing scenarios where the PC is required to be running, yet seem Off (no display or sound); when entering Away Mode, the display is Off, audio is muted, and keyboard and mouse input are ignored. Away Mode is not recommended for enterprise deployments. |
| When playing video | Don't change, Optimize Video Quality, Balanced, Optimize Power Savings | Windows 7 |
Specifies whether Windows Media Player favors power savings or performance in playing video content. Optimize Video Quality - Favor video quality at the expense of power savings. Balanced - Balance video quality and power savings. Optimize Power Savings - Favor power savings at the expense of video quality. |
| Device idle policy | Don't change, Performance, Power Savings | Windows 7 |
Determines whether Conservation idle timeouts or Performance idle timeouts are used for devices that are integrated with Windows kernel power manager device idle detection. Performance - Performance idle timeouts are used. Power Savings - Conservation idle timeouts are used. |
| PCI Express link state | Don't change, Off, Moderate savings, Maximum savings | Vista, Windows 7 |
Governs the power management state for the PCI Express bus (if present). Experiment with the two power saving levels; higher-end graphics cards may present display issues if this is set too aggressively. |
| Turn off hard disks | After x minutes, After x hours, Never | XP, Vista, Windows 7, Macintosh |
The period of inactivity before the disk is automatically powered down. |
| USB selective suspend | Disable, Enable, Don't change | Vista, Windows 7 |
Turns off internally integrated USB devices when idle, yet maintains near-real-time availability by reawakening these devices when ready for use. Mostly reliant on device driver support. |
| Wireless adapter |
Don't change, Max performance, Low power saving, Mid power saving, Max power saving |
Vista, Windows 7 |
These power saving choices enable the wireless adapter to consume less power by sleeping and waking periodically; however, note that this depends in part on the cooperation of the access point. Connectivity and/or throughput issues may be an indication that this is set too aggressively. |
