Power
Different states may be used, depending on whether the notebook
is running on external or battery power. After a power scheme has
been set, no other intervention is required to control the
performance of your notebook processor. The following table
describes the processor performance on external and battery
power for the available power schemes.

Home/Office Desk
Always runs at the highest
performance state.
Performance state is
determined based on CPU
demand.

Presentation
Performance state is
determined based on CPU
demand.
CPU performance is lower
on battery power, then
steadily decreases as the
battery discharges.
Always On
Always runs at the highest
performance state.
Always runs at the highest

Max Battery
Performance state is
determined based on CPU
demand.
Starts at lowest
performance state, and
then uses linear
performance reduction
(stop-clock throttling) as the
battery discharges.
