Abstract

In an information handling system including a keyboard and a visual display device, a representation of the keyboard is reproduced on the display which resembles the physical layout of the keyboard as closely as possible. Testing of the keyboard hardware is accomplished by depression of each of the keys on the keyboard. As each key is correctly tested, its corresponding symbol on the display is altered for the remainder of the test, for example, by blinking. At the end of the test, all of the keyboard keys reproduced on the video display should appear in the altered state. Any key whose display representation does not appear in the altered state is considered to have failed the test. This technique presents an immediate and unequivocal feedback to the operator of any faulty or malfunctioning keys in the keyboard.
