<Only for model with Built-in Bridge Battery>
n The computer is equipped with a built-in bridge battery (not replaceable) and a battery pack(replaceable).
How to use the battery with minimal deterioration
The battery is a consumable and, as such, its performance willgradually deteriorate. Thisdeterioration isaccelerated under the following conditions.
When the battery is repeatedly charged
When the battery is used, charged or stored in a place with high temperature
To minimize deterioration of the battery and ensure a longer battery life, you must reduce the number of charges and ensure that the temperature inside
the battery does not become too high. Bear in mind the following points.
N O T E
n The battery packgradually deteriorates over time even if cared following the above points. If it deteriorates, be sure to replace with a new and
specified battery pack.
n This computer reduces the fullcharge capacity in stages to ensure a longer life of the battery pack.
Charge the battery in a temperature range of 10°C to 30°C {50°F to 86°F}
In places where the outside air temperature ishigh, the temperature inside the battery willalso become high. Do not charge the battery inside a vehicle
with all itswindows closed and exposed to the hot sun or in other places where the temperature is high.
Thiscomputer's battery will not be charged if its temperature is outside the allowable range. (At such a time, the battery indicator blinksorange.)
We recommend charging the battery no more than once per day
Recharging the battery after every small use raisesthe total number of battery charges and speeds battery deterioration.
To lower the total number of battery charges, we recommend recharging the battery no more than once per day or when the remaining charge drops to
10% or less.
With thiscomputer, in order to reduce the number of charges, the battery willnot be recharged immediately after it has been fully charged unless the
remaining charge has fallen to less than 95 %.
Charging the battery while the computer is powered off is recommended
If the computer's power is on, the temperature inside the battery rises due to the effects of heat from the CPU and other components. We recommend
that you onlycharge the battery when the computer is powered off.
How to use the computer to maximize the battery operation time
Leave the computer off when it is not in use
Decrease the internal LCD brightness by pressing ≪Fn≫ + ≪F1≫
Pressing ≪ Fn≫ + ≪ F1≫ willlower the degree of brightness, thereby reducing the power consumption.
Before stepping away from your computer, press ≪Fn≫ + ≪F7≫ or ≪Fn≫ + ≪F10≫ to put your computer in the sleep or
hibernation mode
Pressing these key combinations willput your computer in the sleep or hibernation mode, thereby lowering the power consumption.
