Using Power Management
Decreasing LCD Brightness
Adjust the brightness control on the LCD to the lowest level possible
that allows you to comfortably view the screen. This is an effective
way of conserving battery power.
Using the Battery Power-Management Function
To install the ThinkPad Features
program:

Note:
When you install an operating
system, you must install the
ThinkPad Features program using
the Utility Diskette.
Your computer has the following built-in battery power-saving
functions to save power when you use the battery pack or AC
Adapter:
Operation modes. The operation modes control the processor
speed or set timers for saving power. For more information
about the operation modes, see
2
on page 35.
Power-saving modes. The power-saving modes stop all tasks
when the computer is not used for a specified time.
When resuming normal operation from one of the modes, use
the resume function to return to where you were when you
entered that mode. Because the operating system is already
loaded, the resume function is faster than turning on the power.
The following are the three power-saving modes:
Standby mode You can enter standby mode for short idle times,
such as when you are taking a short break from
work.
Suspend mode You can enter suspend mode for somewhat longer
times when you are away from your computer.
Hibernation mode
You can enter hibernation mode when you leave
your office for the day.
It takes more time to return to normal operation from suspend mode
than to return from standby mode, but the computer does not use as
much power.
