Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of abnormality in a battery switching circuit and to secute the safety of a system by arranging a temperature sensing means in the vicinity of a change-over switch, and when the switch temperature exceeds a prescribed temperature, interrupting the switching circuit. SOLUTION: The circuit is constituted so as to connect the gate electrodes of respective FETs1 to 4 to 1st and 2nd series circuits 10, 20 in order to switch 1st and 2nd battery packs 30, 34. A temperature sensor 50 is arranged in the vicinities of these FETs 1 to 4 and a node G is connected to ground so as to control the switching of the FETs1 to 4. When the temperature of the sensor 50 is increased, its resistance value is increased and a transistor(TR) TR5 is conducted. Therefore the collector of the TR TR5 is turned to low potential and its gate electrode is turned to a non-conductive state. Thus the node G is separated from the ground, the FETs1 to 4 are turned off and all batteries are separated. A level applied to an FET5 shuts down the system as a shut- down signal.

Abstract: PROBLEM TO BE SOLVED: To provide the power control method and device of a computer and the computer for preventing a user from being given any unnecessary uneasiness, and for suppressing the recurrence of any problem at the time of supplying power. SOLUTION: When a power source switch is depressed, its own diagnostic test (POST) is started, and when any error related with the initialization of an IC is not generated at the time of the test, an operating system OS is loaded so that an operating state can be obtained (steps 200-208). When any error is generated, whether or not the error is generated not less than the prescribed number of times is judged, and when the error is generated not less than the prescribed number of times, error display is operated, and then main processing is ended. When the error is not generated not less than the prescribed number of times, an error history is stored, and setting for stabilizing hardware is operated, and a restart signal being a signal for restarting the computer is transmitted, and then the main processing is ended (steps 210-220).
