ELECTRONIC SYSTEM, ELECTRONIC DEVICE AND METHOD CAPABLE OF ERASING PASSWORD FROM BASIC INPUT/OUTPUT SYSTEM AUTOMATICALLY

摘要

A method capable of erasing a password from a BIOS automatically includes steps of the BIOS determining whether a password erasing flag has been set when an electronic device is booting; the BIOS erasing the password if the password erasing flag has been set; the BIOS displaying a password input window if the password erasing flag has not been set; inputting a comparison data in the password input window; the electronic device transmitting the comparison data to a server; the server comparing the comparison data with a registration data, generating a comparison result, and transmitting the comparison result to the electronic device; the BIOS determining whether the comparison result is correct; the BIOS setting the password erasing flag and rebooting the electronic device if the comparison result is correct; and the BIOS rebooting the electronic device directly if the comparison result is wrong.

1. An electronic system capable of erasing a password from a basic input/output system (BIOS) automatically comprising:
a server comprising a first processing unit, a first storage unit and a first communication unit, the first processing unit being electrically connected to the first storage unit and the first communication unit, the first storage unit storing a registration data, the registration data comprising a registration code and a device serial number; and an electronic device having the registration code and the device serial number, the electronic device comprising a second processing unit, a second storage unit, a second communication unit, a BIOS memory, a display unit and an input unit, the second processing unit being electrically connected to the second communication unit, the BIOS memory, the display unit and the input unit, the second storage unit being electrically connected to the BIOS memory, the second communication unit communicating with the first communication unit, the BIOS memory storing the BIOS, the BIOS recording at least one password; wherein when the electronic device is booting, the BIOS determines whether a password erasing flag has been set; if the password erasing flag has been set, the BIOS erases the at least one password; if the password erasing flag has not been set, the BIOS displays a password input window in the display unit; after the input unit is operated to input a comparison data in the password input window, the second processing unit transmits the comparison data to the server through the second communication unit and the first communication unit, the comparison data comprises the registration code and the device serial number; the first processing unit compares the comparison data with the registration data, generates a comparison result, and transmits the comparison result to the electronic device through the first communication unit and the second communication unit; the BIOS determines whether the comparison result is correct; if the comparison result is correct, the BIOS sets the password erasing flag and reboots the electronic device; and if the comparison result is wrong, the BIOS reboots the electronic device directly.
