Method and apparatus for activating a power interlock system and automatically disabling a power supply in a computer having PCI slots

摘要

According to the present invention, an apparatus and method for providing a power interlock system for computers with PCI slots is disclosed. An internal power lock apparatus according to a preferred embodiment of the present invention has a PCI detection circuit which senses the presence or absence of a PCI card or access port cover for each and every PCI slot in the computer. If any of the PCI slots do not have a PCI card installed and do not have an access cover to prevent access to the open slot, the PCI detection circuit activates the power interlock system and automatically disables the power supply.
