Patent ID: 7849234

Claim:
A system for detecting a peripheral device to determine whether the peripheral device is completely inserted into a corresponding peripheral interface slot of a motherboard before booting, the system comprising: a logic component having a plurality of input terminals, the input terminals of the logic component being electrically connected to a first test pin and a second test pin of the peripheral interface slot, respectively, wherein the first test pin and the second test pin respectively correspond to ground pins of the peripheral device when the peripheral device is inserted into the peripheral interface slot, the logic component outputting a judgment value according to a potential of the first test pin and the second test pin; a detecting unit electrically connected to an output pin of the logic component, the detecting unit judging whether the peripheral device is inserted into the peripheral interface slot according to the judgment value, wherein when the detecting unit detects the peripheral device has not been completely inserted into the peripheral interface slot before booting, the booting procedure of the motherboard is interrupted and an alarm signal is sent out; and a power supply unit electrically connected to the detecting unit and the peripheral interface slot, the power supply supplying different electric power before booting and after booting.
