Battery Tips
Tip 1. Avoid excessive heat and cold

Your battery will last longer during the day if it is used, charged and stored between 50
°
F and
86
°
F (10
°
C and 30
°
C).

Charge the battery nightly where the temperature will remain around 68
°
F (20
°
C). Your battery
may not last as long through the day if you charge it at higher or lower temperatures.

Allow unrestricted airflow while the computer is connected to external power. Make sure that the
fan inlet and outlet are unobstructed.

Avoid exposing batteries to hot or cold temperatures for long periods.
How your battery behaves in warm conditions

To prevent possible damage to the battery, the system may not allow a charge if the battery
temperature is above 122
°
F (50
°
C), such as in a closed, unattended vehicle during the summer.
In this case, the Battery Power Indicator may indicate that the computer has stopped charging
your battery; however, your battery may not be fully charged.

If possible, turn off or suspend your computer while the battery is charging in a warm environment
to avoid over-heating.

In warmer temperatures, your battery may take much longer to fully charge.
How your battery behaves in cold conditions

When using a battery in cold conditions, the battery capacity may drain significantly faster.

To prevent possible damage to the battery, the system will not allow a charge if the battery
temperature is below 41
°
F (5
°
C), such as in a closed, unattended vehicle during the winter. In
this case, the Battery Power Indicator may indicate that the computer has stopped charging your
battery; however, your battery may not be fully charged.

In cooler temperatures, your battery can take much longer to fully charge.
Tip 2. Prevent wasted power

Manually turn off or suspend your computer whenever you are not using it.

Reduce the screen brightness. Decrease brightness by pushing Fn + Rotate . Increase it by pushing
Fn + Security .

Use the AC adapter or vehicle adapter whenever possible.

Select either the Portable/Laptop or Max Battery power scheme. Both of these power schemes
help to conserve battery power. Max Battery provides the most battery conservation by always
keeping the processing speed lower. However, this may affect your application performance.
Portable/Laptop automatically adjusts the processing speed as required by your applications.

When running on battery power, make sure your system suspends automatically after a few
minutes of inactivity. PC Cards, radios, custom applications, or modified system settings may
affect this.

Remove PC Cards and unplug peripherals when you are not using them. They may draw power
from the system even when not in use.
