4.6.5 Enhanced C-State support
Enhanced C-States are idle states for the CPU, in which more parts of the CPU are temporarily
disabled than in normal C-State. This way, these enhanced C-state allow a more significant
reduction of power consumption.
4.6.6 Maximum C-State allowed
This option allows selecting which is the deepest sleep state (C-State) that the CPU can reach.
Possible values are C1, C2, C3 or C4.
4.6.7 T-State support
This option allows enabling or disabling
CPU’s Intel T-States management.
4.6.8 ACPI S4/S5 Shutdown
This menu item allows enabling or disabling S4 and S5 states management by the O.S.; this is
particularly useful in systems powered in AT mode, to prevent the O.S. to shutdown automatically
the voltage rails without advising the user.
