Calibration of the battery device for a portable computer system
First Claim
1. A calibration apparatus for a battery device of a portable computer system, which includes a parallel port interface, a main board circuit, the battery and a power-supply board circuit, the calibration apparatus inputting an alternating current supply, comprising:
- a standard parallel port interface coupled to the parallel port interface of the portable computer system for generating at least a control signal;
a control circuit, inputting the control signal, for selectively outputting the alternating current supply to the power-supply board circuit to perform charge/discharge operation of a predetermined type.

Abstract
A capacity calibration apparatus for the battery of a portable computer system is provided. The computer system includes a main board circuit, a processor unit, a display unit, a power-supply board circuit, a battery and a parallel port interface. The capacity calibration apparatus includes a standard parallel port interface and a control circuit. The standard parallel port interface is connected to the parallel port interface of the computer system. Via the parallel port interface, the computer system outputs at least one control signal to the capacity calibration apparatus. The capacity calibration apparatus selectively outputs the alternating current supply to the power-supply board circuit in order to proceed a charge/discharge procedure of a predetermined type such that the capacity value of the battery is initialized.
