Abstract
A method for displaying reasons of computer hardware faults by light emitting diodes on a keyboard is disclosed. Some parts of the program of the basic input/output system (BIOS) are addressed to the light emitting diodes on a keyboard. Then the programmed numerical codes are outputted so that the basic input/output system performs a power on self-test (POST). By the illumination of the light emitting diodes and checking up a table, the fault condition can be known.
Claims3
A method of visually signaling hardware faults of a computer on a keyboard coupled thereto, comprising the steps of:
- a. addressing at least a portion of a basic input/output system to a plurality of light emitting diodes disposed on the keyboard;
- b. fault testing a plurality of hardware components of the computer;
- and,
- c. dynamically actuating said light emitting diodes in a manner responsive to said fault testing of hardware components for visually indicating on the keyboard a unique numerically coded identity for a corresponding one of said hardware components when a hardware component fault is detected.
