Battery Pack
When not connected to an external power source, your notebook operates with the
rechargeable battery pack. The battery pack, when fully charged, can provide
power to your notebook for up to 1.5 hours. The duration of the battery life may be
longer if the notebook’s Power Management is active. An optional battery pack,
which is the same type with the standard battery pack, is also available.
• When the battery is not charged, your notebook may not operate
properly. Connect the AC adapter to charge the battery.
• If you see the message Press <F1> to resume, <F2> to SETUP in the
booting time, press F2 to open the Setup Utility. Press Esc; then,
Enter twice. The system restarts.
Installing the Battery Pack
You can install the battery pack either right- or left-side bay of your notebook as in
the same way with other units. See Chapter 2.
• Before installing or uninstalling the battery pack, turn off your
notebook. If not, the system may malfunction or the data may be lost
• Incorrect installation of the battery is dangerous. Replace the battery
only with Sharp's optional battery packs. Discard used batteries
according to the dealer's instructions.
The procedure for recharging an optional battery pack is the same as the
standard battery.
