Abstract:
1. A current overload detecting system applicable in a data processing device connected with a plurality of electronic devices, wherein each of the electronic devices having a universal serial bus (USB) interface, and wherein the data processing device having a plurality of USB ports corresponding to and connected with the USB interfaces, a plurality of USB control units for controlling the operation of the USB ports, and a basic input/output system (BIOS) for executing a power-on self test (POST) process, the current overload detecting system comprising: a signal-detecting unit for detecting whether the USB control unit of the data processing device outputs an over-current signal when the BIOS of the data processing device executes the POST process, and for outputting a control signal in the case that the USB control unit is detected to have output the over-current signal; and a display unit for receiving the control signal output by the signal-detecting unit and displaying corresponding messages according to the received control signal, so as to inform a user that at least one of the electronic devices is detected to be currently in a current overload status.
