Abstract

An input power source voltage detecting unit 1 detects the input AC power source voltage on an electronic device, and a country discriminating unit 2 discriminates the country with the electronic device present therein according to the detected voltage. An operation environment presetting unit 5 presets the electronic device to operation environments of the country discriminated by the country discriminating unit 2.

Claims

1. A personal computer operation environment presetting system comprising:

a power source voltage list for storing AC power source voltages for each of specified countries;

an input power source voltage detecting unit operable, when a wireless LAN card is mounted therein, to detect the personal computer input AC power source voltage permitting operation in a wireless LAN system;

a country discriminating unit for discriminating the country with the personal computer present therein on the basis of the voltage detected by the input power source voltage detecting unit; and

an operation environment presetting unit for presetting the operation environment of the wireless LAN card to the operation environment of the country discriminated by referring to an operation environment list.

2. The personal computer operation environment presetting system according to claim 1, wherein the operation environment list, stores operation environments preset for specified countries.

3. The personal computer operation environment presetting system according to claim 1, wherein the input power source detecting unit executes the detection by utilizing an AC voltage detecting function of an AC-DC adapter for converting AC voltage to DC voltage used in the electronic device.

5. The personal computer operation environment presetting system of claim 1 wherein the country discriminating unit discriminates the country with the personal computer present therein according to only the input power source voltage detected.

4. A personal computer operation environment presetting method comprising:

storing AC power source voltage for each of specified countries in a power source voltage list;

detecting an input AC power source voltage on the personal computer when a wireless LAN card is mounted therein;

discriminating a country with the personal computer present therein according to the detected input AC power source voltage; and

presetting an operation environment of the wireless LAN card to an operation environment of the discriminated country by referring to an operation environment list.
