Notes on Battery

WARNING
ELECTRIC SHOCK
The battery is very sensitive. When you install or remove the battery, be careful not to
subject it to shocks by dropping it or otherwise. For safety, do not use a battery that
has been subjected to shocks, as it may cause an electric shock or burst.
Electric discharge
• The battery continues to discharge even if the computer is not used after charging, so we
recommend you charge the battery immediately before use.
• If you are not going to use the computer for a long time (more than one month), remove the
battery and store it in a cool place. If the battery is left installed in the computer for a long time,
it will discharge excessively and the life of the battery will be shortened.
Battery life
• The battery continues to age and deteriorate even if the computer is not in use for a long time.
Check the battery condition at least once a month by using the computer with the battery power
source.
• The battery is a consumable product and the battery's charging capacity is reduced as the
battery ages.
• If your battery runs low quickly, it is a sign that it is getting old.
Disposing of the battery
When you dispose of a battery, take measures so as to insulate the battery terminals with tape to
prevent short-circuiting. Also, check with your local government authority for details regarding
disposal of batteries.
Prolonging actual battery life
Use the power saving function to prolong the actual battery life.
Conditions where the actual battery life will be shortened
• The actual battery life varies depending on the temperature of use, and may be shortened in a
low temperature environment.
• The battery charging capacity is reduced as the battery ages. If your battery is running low
quickly, you should replace it with a new one.
Use the AC adapter when;
• Performing personal computer communication or Internet communication,
• using the hard disk and CD/DVD frequently,
• using a LAN, or
• restoring the pre-installed software status of the computer when you purchased it.
