9.3 Power Management Modes

9.3.1Dell Active Power Controller

The Dell Active Power Controller (DAPC) is a Dell proprietary implementation that provides improved performance/watt over the OS implementation of Intel’s DBS. DAPC is implemented in system BIOS and uses hardware level counters, etc. to determine hardware utilization. The BIOS uses this information to determine when to change the processor’s operating frequency. The DAPC is OS independent and means that the OS no longer has control. This provides a consistent power management solution regardless of the installed OS. Some OS(s), particularly hypervisors, do not support power management, thus DAPC provides a solution when there otherwise would not be one.
