iv Power Manager Deployment Guide

Chapter 1. Overview

Power Manager helps users adjust power settings to achieve the best balance between system performance and power saving through slider control or power plans.

Power Manager provides a variety of power-saving features through two essential modes, Basic and Advanced. Basic mode is set as default when users open Power Manager for the first time. Users can specify the level of power saving by simply using the slider, without power plans. Advanced mode enables users to configure power plans and the full range of functions in Power Manager to meet specific power saving needs. Power Manager can also display the battery information, and help users monitor the battery status.

Power Management on a computer can save energy and money. When the IT administrator enforces power management strategy on computers throughout the entire organization, the savings can be far more substantial. Power Manager is configured by default to use its energy efficiency features. Power Manager also gives the IT administrator numerous options for tailoring power management settings to optimize energy efficiency throughout their organizations.

Note: Power Manager has two different versions. One is for Microsoft® Windows® XP operating systems and the other is for Microsoft Windows Vista® and Microsoft Windows 7 operating systems. In the Windows Vista and Windows 7 version, the term "power plan" is used. In the Windows XP version, the term "power scheme" is used. In this document, no distinction will be made and the term "power plan" will be used to cover both.

Features

Power Manager includes the following functions:

•Balance the performance and power saving of the computer

Power Manager provides the slider to help users quickly and easily set the level of power to be used. Users can control the Central Processing Unit (CPU) speed and the brightness of the computer display by moving the slider. Moving the slider to the left, toward Maximum Performance, increases the CPU speed and the brightness of the computer display but uses more battery power. Moving the slider to the right, toward Maximum Battery Life, prolongs the battery life while limiting the CPU speed and the brightness of the computer display.

When users move the slider to the leftmost position, the power-saving settings in the predefined Maximum Performance power plan are applied. When users move the slider to the rightmost position, the power-saving settings in the predefined Maximum Battery Life power plan are applied.

•View, create, delete, and switch power plans

A power plan is a collection of hardware and system settings that manages how the computer is used and conserves power. Power Manager power plans provide more power-saving settings than Windows® power plans. On the Power Plan tab, the user can view specific settings in any of the predefined power plans: Maximum Performance, Timers off (Presentation), Video Playback, Maximum Battery Life, Energy Saver (which is called as ThinkPad® Default or Energy Star on some systems), and Power Source Optimized. These predefined power plans are designed to meet the needs of most people. If the predefined power plans do not meet your needs, the Create Power Plan wizard can help you create your own custom power plans. You can easily switch between power plans by clicking the Battery Gauge

icon on the taskbar and using the slider to apply a predefined power plan, or by pressing the F3+Fn keys to select a power plan from the Choose Power Plan menu.

•View battery information

Power Manager displays battery information and general battery status, such as remaining time, remaining capacity, charge and discharge status, cycle count and so on. The battery health indicator can indicate the battery health conditions in three colors: green (in good condition), yellow (in fair condition), and red

(in poor condition). When the battery has encountered an error, an error message or balloon message will display in the notification area.

•Maximize battery life span

If you primarily use the computer with an attached ac power adapter and only infrequently use battery power, you can increase the life span of the battery by changing the charge thresholds. This allows you to reduce the number of charge cycles by letting the battery discharge to a lower percentage before it begins to charge. You can change the battery charge thresholds on the Battery tab.

You can also set the maximum charge value to below 100%. This option is useful to prolong the life span of the batteries that you do not use frequently, because it is recommended to store batteries with less charge rather than full charge.

•Remotely configure Power Manager and deploy power plan

Power Manager enables an IT administrator to configure Power Manager and deploy a power plan using Active Directory. The IT administrator can select an active power plan in the client computers, inhibit the user's ability to switch between power plans, select a specific power plan, or create a power plan. For example, the IT administrator can disable the Maximum Performance power plan and users cannot select it.

Also, the IT administrator can configure settings for the General Setting policies, Power Plan (Scheme) Deployments policies, Global Power Settings policies, and Battery Maintenance policy.
