Power Management
AC Recovery Determines how the system responds when AC power is re-
applied after a power loss. You can set the AC Recovery to:
• Power Off (default)
• Power On
• Last State
Auto On Time Allows you to set the option to automatically turn on the
computer. Time is kept in standard 12-hour format
(hour:minutes:seconds). Change the startup time by typing the
values in the time and AM/PM fields.
NOTE: This feature does not work if you turn off your
computer using the switch on a power strip or surge
protector or if Auto Power is set to disabled.
Deep Sleep Control Allows you to define the controls when Deep Sleep is enabled.
• Disabled
• Enabled in S5 only
• Enabled in S4 and S5
This option is Disabled by default.
Fan Control Override Controls the speed of the system fan. This option is disabled by
default.
NOTE: When enabled, the fan runs at full speed.
Wake on LAN This option allows the computer to power up from the off state
when triggered by a special LAN signal. Wake-up from the
Standby state is unaffected by this setting and must be
enabled in the operating system. This feature only works when
the computer is connected to AC power supply.
• Disabled — Does not allow the system to power on by
special LAN signals when it receives a wake-up signal
from the LAN or wireless LAN.
• LAN Only — Allows the system to be powered on by
special LAN signals.
This option is Disabled by default.
