Abstract

PURPOSE:To improve operability and usability of the personal computer without confirming the remaining battery capacity by calculating the current consumption in a fixed time from the set battery driving time and the total battery capacity and setting the luminance of a display device based on the obtained current consumption. CONSTITUTION:In a set-up state, a message urging the input of the battery driving time is displayed in a set-up routine of a BIOS (basic input/output control system) ROM 1. Then the value of current consumed in a fixed time is calculated by a microcomputer containing a back light power supply 3 from the time inputted via a keyboard 2 and the total capacity of a battery 5. Thus the luminance of the back light of an LCD 4 is set based on the calculated current consumption value so that the power supply 3 is driven by a battery with control for only a time set by a user. As a result, it is not required to confirm the remaining battery capacity since the battery driving time inputted once by the user is available for the set time.

(Function) In a personal computer that can be powered by a battery,
Battery operating time is limited by battery capacity.
It varies depending on the brightness of the LCD backlight. When the brightness is minimum (MIN), the battery driving time is maximum, and when the brightness is maximum (MAX), the battery driving time is minimum. In the present invention, with the above-described configuration, by setting the brightness of the backlight based on the time input by the user at the time of setting the environment, battery operation for the input time is possible.
