Managing CPU power
If your notebook contains a multispeed processor with Intel SpeedStep Technology, the
processor can automatically switch to lower, power-saving speeds or to higher-
performance speeds according to its workload and power source.
You can customize SpeedStep to best suit your working environment: click Start, Control
Panel, Performance and Maintenance, Power Options. On the Power Schemes tab, select
a power scheme. This scheme automatically controls the processor speeds:
?? The Max Battery scheme uses the lowest processor speeds while running on battery
power, but uses medium and high processor speeds on AC power.
?? The Portable/Laptop option uses medium and high processor speeds on battery and
AC power.
?? The Presentation option uses the lowest processor speeds on battery and AC power.
