Option Description
Wake on LAN/WLAN 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. (Default
Setting)
• LAN or WLAN - Allows the system to be powered on by special LAN
signals or WLAN signals.
• LAN Only - Allows the system to be powered on by special LAN signals.
• LAN with PXE Boot - A wakeup packet sent to the system in either the S4
or S5 state will cause the system to wake-up and immediately boot to PXE.
• WLAN Only - Allows the system to be powered on by special WLAN
signals.
Block Sleep Allows you to block the computer from entering into the sleep state. This option is
disabled by default.
• Block Sleep (S3)
Peak Shift Peak Shift can be used to minimize AC consumption during peak power times of
day. For each weekday listed, set a start and end time to run in Peak Shift mode.
During these times the system will run from the battery even if the AC is attached
as long as the battery stays above the threshold specified in the Battery Threshold
field. After the end time specified the system will run from AC if attached but will
not charge the battery. The system will again function normally using AC and
recharging the battery after the Charge Start time is specified. This option is
disabled by default.
• Enable Peak Shift
Advanced Battery Charge
Configuration
This places all batteries in the system in Advanced Battery Charging Mode to
maximize battery health. In Advanced Charging Mode the system will use standard
charging algorithm and other techniques during non-work hours to maximize
battery health. During work hours express charge is used so that the battery will be
charged faster and therefore ready to use again sooner. For each weekday, specify
the time of day in which the system will be most heavily used. Setting the Work
Period to 0 means the system will only be lightly used that day. This option is
disabled by default.
• Enable Advanced Battery Charge Mode
