  • Electronic device capable of automatically controlling power assumption of components employed in accordance with operating time period by user
    Patent number: 5532935
    Abstract: An electronic device including a portable computer or a word processor, which is driven by a battery (13). This device has a device component (47) driven by the battery (13), a menu screen for setting an operation time period during which the device is operated by the battery (13), and a power source controller (37) for detecting the remaining capacity of the battery (13) and controlling the amount of power supplied to the device component from the battery on the basis of an operation time period set on the menu screen and the remaining capacity of the battery. When the user sets the operation time period on the menu screen, the power source controller (37) calculates the amount of power to be consumed by the electronic device for the set operation time period, on the basis of the set time period and the remaining capacity of the battery (13).
