by default. DAPC is Dell Active Power
Controller.
NOTE: All the parameters on the system profile setting screen are available
only when the
System Profile
option is set to
Custom
.
CPU Power

, or a specific speed.
Turbo Boost
Enables or disables the processor to operate in the turbo boost mode. This option
is set to
Enabled
by default.
Energy Efficient
Turbo
