Traveling with Your Computer Managing Power Consumption Managing CPU power (SpeedStep) If your computer's taskbar contains an Intel SpeedStep Technology icon, then your computer contains a dual-speed processor with Intel SpeedStep Technology. This feature enables the processor to automatically switch to a lower, power-saving speed when the computer is running on the battery. • If you reboot the computer with the ac adapter plugged in, the processor starts at its high speed. If you reboot the computer on battery power, the processor starts at its low speed. • If you unplug the ac adapter while the computer is running or in Standby mode, the processor changes to low speed. • If you plug in the ac adapter while the computer is running or in Standby mode, the processor changes to high speed. You can also customize SpeedStep to best suit your working environment. • To set the speed used by the processor at boot, change the Intel SpeedStep Mode setting in the BIOS Setup Power menu-see "To run the BIOS Setup utility" on page 78. • To set the speed used by the processor when Windows is running, double-click the Intel SpeedStep Technology icon in the taskbar. 44 Reference Guide
