ABSTRACT:
A circuit for indicating status of a component of a computer system includes a first indicator (D1), a second indicator (D2), a power supply (V), a first transistor (Q1), and a second transistor (Q2). The first indicator includes a positive end and a negative end. The second indicator includes a positive end connected with the negative end of the first indicator, and a negative end connected with the positive end of the first indicator. The power supply is connected to the positive end of the first indicator via a first resistor, and connected to the positive end of the second indicator via a second resistor. The first transistor is connected between the negative end of the first indicator and a ground, and the second transistor is connected between the negative end of the second indicator and the ground.
