Battery pack - 61
B
ATTERY PACK
The computer uses a battery pack that gives you long use between
charges.
Battery pack characteristics
The battery is recharged whenever you connect the computer to the AC
adapter. Your computer supports charge-in-use, enabling you to recharge
the battery while you continue to operate the computer. However,
recharging with the computer turned off results in a significantly faster
charge time.
The battery will come in handy when you travel or during a power failure. It
is advisable to have an extra fully charged battery pack available as
backup. Contact your dealer for details on ordering a spare battery pack.
Charging the battery
To charge the battery, first make sure that it is correctly installed in the
battery bay. Plug the AC adapter into the computer, and connect to a
mains power outlet. You can continue to operate your computer on AC
power while your battery is charging. However, charging the battery with
the computer turned off results in a significantly faster charge time.
Note: You are advised to charge the battery before retiring for the day.
Charging the battery overnight before traveling enables you to start
the next day with a fully charged battery.
