Method for automatically restoring system configuration with a single key

A method for automatically restoring a system configuration with a single key, wherein the method is used to set/recover system configuration parameters in order to ensure a normal boot-up sequence, wherein the method comprises:

• detecting a mode of press modes of a power button;
• determining one of restoring items according to the mode;
• restoring the system configuration corresponding to the one of the restoring items;
• and
• performing a normal boot process,
• wherein the restoring items comprise commands of clearing information stored in a CMOS memory, restoring original system configuration setting, and rewriting a BIOS program, and each one of the press modes corresponds to a different one of the restoring items,
• wherein
• when the power button is pressed twice for two different durations, the step of clearing information stored in the CMOS memory is executed;
• when the power button is pressed for a first duration and sequentially pressed twice for a second duration equally, the step of restoring the original system configuration setting is executed;
• and
• when the power button is pressed for the first duration and sequentially pressed three times for the second duration equally, the step of rewriting the BIOS program is executed.
