Tips for Conserving Battery Power 2
You can extend the charge life of your battery pack by conserving battery power.
Battery life is dependent upon a number of factors: operating system, power settings,
and applications or peripherals in use. Here are some suggestions to help you
conserve battery power:
• Use an external power source such as the AC adapter to power the system when
possible.
• Suspend system operation if you won’t be using the system for a while.
• Shut down the system if you won’t be using the system for an extended period of
time.
• Use power management timeouts (accessible through the BIOS setup) to help
conserve power automatically. Contact your reseller before modifying the BIOS.
Operation of the Bridge Battery 2
When installed in the tablet, the battery pack provides power to some system
components—even when the system is in the Off state. When the battery pack is
removed, power is supplied to these components by a “bridge” battery that is built
into the tablet.
The bridge battery is not designed for long-term operation (it will support a
suspended system for between five and ten minutes). To maintain the bridge battery
properly, observe the following measures:
Note: The system arrives with the bridge battery in a discharged state.
• To prevent draining the bridge battery, always store the tablet with a charged
battery pack installed.
• If the bridge battery becomes drained, it takes approximately 11 hours for it to
be fully recharged.
• The bridge battery charges from the AC Adapter when the adapter is connected
and the system is in On or Off states or Suspend mode. It charges from the
battery only when the system is in the On state.
