System Setup
Auto Power Time Specifies the time to automatically turn on the computer.
Set the time to automatically turn on the computer by pressing
the up- or down-arrow key to increase or decrease the numbers,
or type the numbers in the appropriate time field.
NOTE:
This feature does not work if you turn off your computer
using a power strip or surge protector.
Low Power Mode
(Off default)
Specifies how aggressive the system is at conserving power
while in Hibernate mode or when turned off.
• Off — Add more functionality.
• On — Conserve more power.
NOTE:
Setting this option to On disables the integrated NIC when
the computer is in Hibernate mode or turned off. Only an add-in
NIC can be used to remotely wake the system.
Remote Wake Up
(Off default)
Specifies whether the computer can be turned on when a NIC
receives a wake up signal.
• Off — The NIC cannot wake up the system.
• On — The NIC can wake up the system
• On w/Boot to NIC — The NIC can wake up the system, and
the system will boot from the network.
NOTE:
The system can be powered on remotely from Suspend
mode, Hibernate mode, or when turned off.
NOTE:
When Low Power Mode is set to On, the system can only
be powered up from Suspend mode. If Remote Wake Up from
Hibernate or Off is required, Low Power Mode must be set to
Off.
Suspend Mode
(S3 default)
Specifies the power management suspend mode.
• S1 — The computer resumes more quickly from sleep mode.
• S3 — The computer conserves more power when not in use
(system memory remains active).
