Using Battery Power

Reference Guide
•
If you work with an application that uses the serial port or an I/O PC card, exit the
application when you have finished using it.
•
Turn off the CD player when you are not using it.
•
For a model with a dual-speed processor, use the lower speed on battery power (see
“To control the processor speed” on page 52). The default settings conserve battery
power.
•
See “Managing Power Consumption” on page 46 for other ideas about reducing
power consumption while the computer is not in use.
To control the processor speed
If your computer contains a high-speed Pentium III processor with Intel SpeedStep
Technology, you can change settings that control the processor speed. Your computer has
this feature if the taskbar contains an Intel SpeedStep Technology icon (a checkered flag).
With the default settings, the processor speed changes automatically according to the
power source (AC adapter or battery). The lower speed uses power more efficiently and
is typically in effect when the computer is running on battery power.
To use automatic speed changes
•
If you reboot the computer with the AC adapter plugged in, the processor starts at
high speed. If the computer is on battery power, the processor starts at low speed.
•
If you unplug the AC adapter while the computer is running or on standby, the
processor changes to low speed.
•
If you plug in the AC adapter while the computer is running or on standby, the
processor changes to high speed.
To change speed settings
•
To set the speed used by the processor at boot, or to disable the dual-speed feature,
change the Intel SpeedStep Technology setting in BIOS Setup in the Power menu. For
information on how to run BIOS Setup, see “Using the BIOS Setup Utility” on page
78.
•
To set the speed used by the processor while Windows is running, double-click the
Intel SpeedStep Technology icon in the taskbar or use the Control Panel Power icon.
