Resumen del manual
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
