Abstract

A computer system with a device for indicating the network signal level of the LAN connected to the computer system is provided. The network signal level indication device includes a network signal level detection unit for detecting the signal level of the LAN connected to the computer and generating a set of network state signals, an indication unit interface circuit for receiving the set of network state signals generated by the network signal level detection unit, and a network signal level indication unit for receiving the set of network state signals and generating a light signal indicating the network signal level. The network signal level detection unit is the keyboard controller of the computer system.

Claims

1. A computer system with a network signal level indication device for indicating network signal level of a local area network (LAN) connected to the computer system, the network signal level indication device comprising:

a network signal level detection unit, connected to the computer system for detecting the signal level of the LAN connected to the computer system and generating a set of network state signals;

an indication unit interface circuit, connected to the network signal level detection unit for receiving the network state signals generated by the network signal level detection unit; and

a network signal level indication unit, connected to the indication unit interface circuit for receiving the network state signals through the indication unit interface circuit to generate an indication signal to indicate the network signal level.

2. The computer system as claimed in claim 1, wherein the network signal level detection unit comprises a keyboard controller connected to the computer system.

3. The computer system as claimed in claim 1, wherein the network signal level indication unit comprises a plurality of light-emitting diodes (LED) connected respectively to the indication unit interface circuit for indicating the network signal level using on/off state.

4. The computer system as claimed in claim 3, wherein the LEDs are connected respectively through corresponding driving elements of the indication unit interface circuit to the network signal level detection unit.

5. The computer system as claimed in claim 1, wherein the network signal level indication unit comprises a multi-color light-emitting diode (LED) for indicating the network signal level by using different colors.

6. The computer system as claimed in claim 5, wherein the multi-color LED is connected to the network signal level detection unit through a digital-to-analog converter.

7. The computer system as claimed in claim 1, wherein the network signal level indication unit is arranged at a pre-determined location of a case of the computer system.
