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 the BIOS is configured to determine whether a password erasing flag has been set when the electronic device is booting; the BIOS is configured to erase the at least one password when the password erasing flag has been set; the BIOS is configured to display a password input window in the display unit when the password erasing flag has not been set; the second processing unit is configured to transmit a comparison data to the server through the second communication unit and the first communication unit after the input unit is operated to input the comparison data in the password input window, the comparison data comprising the registration code and the device serial number; the first processing unit is configured to compare the comparison data with the registration data, generate a comparison result, and transmit the comparison result to the electronic device through the first communication unit and the second communication unit; the BIOS is configured to determine whether the comparison result is correct; the BIOS is configured to set the password erasing flag and reboot the electronic device when the comparison result is correct; and the BIOS is configured to reboot the electronic device directly when the comparison result is wrong.
