4.6 POWER MANAGEMENT
In addition to C1, C2/C2E, C3 and C4/C4E states at system full on state, the S62F platform must also
support suspend states described in next two sections.

4.6.2 ACPI 2.0
S62F BIOS is ACPI 2.0 compliance. It supports Windows XP Native Processor Performance Control.
In Windows XP, the processor performance control policy is linked to the Power Scheme setting in
the standard control panel power options applet. No additional UI is employed to set the policy.
Windows XP defines four control policies for processor performance control:
Constant Always runs at lowest performance state
Adaptive Performance state chosen based on CPU demand
Degrade Starts at lowest performance state, then uses linear performance reduction (stop
clock throttling) as battery discharges
None Always runs at highest performance state
The following table shows the relationship between the Power Scheme selected and the control
policy used.
