Using Intel SpeedStep
NOTES: Intel SpeedStep technology is only available for C600 computers.
The Intel SpeedStep technology allows you to set the performance level of the microprocessor whether the
computer is running on battery or AC power. You can only use the Intel SpeedStep technology applet when
the Microsoft® Windows® 98, or Windows 2000 operating system is running. You can verify or change the
processor's performance mode when running in MS-DOS® mode by entering the system setup program
.
The first page lists the processor speed ranges.
To access the Intel SpeedStep properties window, perform the following steps:
1. Right-click the flag icon in the system tray on the Windows taskbar to access performance level
options. The following three options appear:
Maximum Performance option — switches your computer to the highest possible
performance level even if the computer is running on battery
Battery Optimized Performance option — lets your computer run on performance
level optimized for battery power even if the computer is connected to an electrical outlet
Adjust Properties — lets you change more performance options
2. To change the performance level, click the desired option.
To access the Intel SpeedStep options when the flag icon is not visible on the taskbar and if your computer is
running under ACPI, perform the following steps:
1. Click the Start button and point to settings.
2. Click Control Panel.
3. Click Power Management.
4. Select the Intel SpeedStep tab and select the options desired.
5. After you make any changes, click OK to accept the settings and close the Intel SpeedStep window.
