Method for automatically simulating manual testing after powering on of computer, detection system, and external storage device

In a method for automatically simulating manual testing after powering on of a computer, the computer has a BIOS program for executing the method. The method includes the following steps: (a) connecting the computer to an external storage device that has a script corresponding to a manual testing task recorded thereon; and (b) reading the script from the external storage device after powering on of the computer so as to execute the manual testing task. Since conventional testing processes of manually inputting instructions into individual computers are time-consuming, the present invention, which provides automatic simulation of manual testing after powering on, can effectively save time and labor costs.
