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.
• WLAN Only - Allows the system to be powered on by special WLAN signals.
Allows you to block the computer from entering into the sleep state. This option is disabled
by default.

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
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
