Section 6. Managing Batteries and Power
79-0030-001 11 January 2001
In cold conditions
• When using a battery in cold conditions, the battery capacity can
drain 30 percent faster at 4°C (39°F) and 70 percent faster at -11°C
(19°F).
• To prevent possible damage to the battery, the system will not allow
a charge if the battery temperature is below 5°C (41°F), such as in a
closed, unattended vehicle during the winter.
• If possible, charge the battery in a location with a moderate
temperature of around 20°C (68°F). The battery wont last as long
during the day if charged at lower temperatures because cold slows
down the batterys chemical reactions.
Tip 5. Preventing data loss
How to prevent data loss when removing the battery or storing
your computer
• You can lose data if you remove the battery while the computer is
operating on battery power. To prevent this, turn off the unit by
pressing
FN+OFF before you remove the battery.
• The computer is equipped with enough internal backup power to
maintain memory contents for about 5 minutes each time you
exchange batteries. Be careful not to exceed this 5 minute limit
when you replace the battery.
• If you plan to store your computer for more than 30 days, shut down
your computer to save data to the hard disk, and then press
FN+OFF
to turn off the computer. Remove the battery before storing the
computer.
Tip 6. Returning batteries for service
• When shipping batteries, use non-static packing material to reduce
the possibility of static discharge. Placing the battery in a non-static
bag is ideal; however, wrapping the battery in paper or newspaper is
also acceptable.
• Contact your supervisor or your organizations help desk for correct
shipping procedures and information.
