Important Battery Tips
1. Charging the battery
Charge the battery until the battery indicator turns green only when it is completely dis-
charged
The battery deteriorates each time it is charged. By charging the battery only when it has become completely discharged,
you will reduce the number of charges, and thus extend the life of your battery. Do not charge the battery repeatedly
before it is discharged.
To help reduce the number of charges, the battery can only be recharged when the remaining power is less than
about 95% of capacity.
Charge the battery in a temperature range of 10°C to 30°C {50°F to 86°F}
The battery deteriorates more quickly when it is charged at high temperatures. Do not charge the battery in high temper-
ature environments, such as in a closed car in the hot sun.
When the battery temperature is outside the allowable temperature range, the battery indicator blinks orange and charg-
ing will not begin.
Charge the battery while the computer is powered off
Even if the environmental temperature is within the allowable temperature range, if the computer's power is on, the battery
temperature rises due to the effects of heat from the CPU and other components. Since this heat can lead to deterioration
of the battery, we recommend that you only charge the battery when the computer is powered
off.
Use high temperature mode
*1
Models for which [Environment] is displayed in [Main] menu of the Setup Utility.
High temperature mode is a function that prevents deterioration of the battery in high temperature environments or when
using the fully charged battery pack for a long period of time.
The high temperature mode function is recommended in the following situations:
When the computer is installed in a vehicle.
When the computer is installed where the temperature may rise above the allowable temperature range.
When the computer is used for a long period of time with its AC adaptor connected.
When long-term battery operation is not required.
To use this function, set [Environment] in the [Main] menu of the Setup Utility to [Auto] or [High Temperature].
