ACPI Configuration
This section configures system ACPI parameters.
ERP
Enable or disable the ERP (Energy-related Products) support. Disable the ERP support to
allow the system to consume power so it may continue to supply power to devices on the
system such as the USB and LAN ports. Or enable the ERT support to not allow the system
to consume power in S4 (hibernate) and S5 (soft-off ) states. The default is enabled.
Wake on LAN
Enable or disable WOL (wake-on-LAN) to wake the system through an Ethernet adapter.
CPU Configuration
This section configures the CPU.
EIST
Enable or disable the Enhanced Intel
®
SpeedStep
®
Technology, which helps optimize
the balance between system’s power consumption and performance. After it is enabled
in the BIOS, you can take advantage of its offering by setting power schemes from the
operating system’s power options.
Turbo Mode
Enable or disable processor turbo mode, which allows the processor core to automati-
cally run faster than the base frequency by taking advantage of thermal and power
headroom. Note this option is not available on the Core™ i3 processor.
C-States
Enable or disable CPU power management. It allows the CPU to go to C states when
it’s not 100% utilized.
Note:
WOL (wake-on-LAN) will be disabled if ERP is enabled.
