Abstract
A personal computer system is provided with a detachable hard disk pack, a lock mechanism for locking the hard disk pack into the system, a switch which turns on and off in cooperation with the lock and release operations of the lock mechanism. When the hard disk pack is detached from the system, while the system is being powered, the switch turns off in cooperation with the release operation of the lock mechanism. In response to the changed state of the switch, the NMI control section outputs an NMI signal to the CPU. In response to the NMI signal, the CPU instructs a power controller to cut off the power. The CPU determines in response to the system being powered if the hard disk pack is attached to the system. If the hard disk pack is not attached, the CPU instructs the power controller not to supply the power to the system.
