computer is powered off.

Use the battery in the high temperature mode

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.

When the high temperature mode is selected, the battery capacity is reduced, and therefore the battery operating time is shorter.

We recommend the high temperature mode setting when the computer is to be used under the following conditions:

When the computer is to be used in a vehicle

When the computer is to be used in a place with high temperature

When the computer is to be used for extended periods of time with the AC adaptor connected

When battery operation is not required for long hours (When the battery’s remaining capacity does not often drop to 40% or below in normal temperature mode)

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» will lower 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*1 or hibernation mode

Pressing these key combinations will put your computer in the sleep*1 or hibernation mode, thereby lowering the power consumption.

*1 : Windows XP: standby

Click or in the notification area, and select a power plan that uses the power-saving function.
