In a computer system wherein an extended unit (10) is connected to a computer main body (1), a power supply unit (11) and power monitoring circuitry (12) which are independent of the computer main body (1) are arranged in the extended unit (10). The computer main body (1) includes reset control circuitry (5) for outputting a signal corresponding to a system reset signal (SR) on the basis of a signal (Mb) representing an abnormal power and output from power monitoring circuitry (12) of the extended unit (10). The computer main body (1) includes logic gate circuitry (6) for outputting the system reset signal (SR) generated upon the power failure on the basis of an output signal from the reset control circuitry (5) or a signal (Ma) representing the abnormal power and output from power monitoring circuitry (4) for monitoring the power supply state of the computer main body (1). <IMAGE> |
