Intel SpeedStep®Tab
Depending on your operating system and microprocessor, the Power Options Properties window includes the Intel SpeedStep®tab. The Intel SpeedStep
technology allows you to set the performance level of the processor according to whether the computer is running on battery or AC power:
l Automatic — The processor runs at its highest possible speed (Maximum Performance mode) when the computer is running on AC power. When the
computer is running on battery power, the processor runs in Battery Optimized mode.
l Maximum Battery — The processor runs at a slower speed to extend battery life.
l Maximum Performance — The processor runs at its highest possible speed even if the computer is running on battery power.
l Battery Optimized Performance — Processor speed is optimized for battery power even if the computer is connected to an electrical outlet.
To change additional Intel SpeedStep options:
1. Click the Advanced button and then click one of the following options:
l Disable Intel SpeedStep technology control
l Remove flag icon (from the notification area)
l Disable audio notification when performance changes
2. Click OK to accept any changes, and then click OK to close the Intel SpeedStep window.
You can also change the Intel SpeedStep settings by right-clicking the flag icon in the notification area.
NOTE: Windows XP controls the performance level of the processor depending on the power scheme that you select. See "Power Schemes Tab."
