Abstract

A panel device mounted on a computer case comprises an adjustment unit for adjusting CPU'"'"'s operating frequency, a display module for showing system information, and a microprocessor which interconnects the adjustment unit and the display module with the computer system. The microprocessor can perform adjustment done by the adjustment unit and issue a service request signal to the computer. In response, the computer issues signals about system information to the microprocessor for being processed and showed on the display module.

Claims

1. A panel device mounted on the front side of a computer case for adjusting operating frequency and showing system information of the computer including a central processing unit (CPU), a basic input output system (BIOS), a system management (SM) bus and a system clock generator, the system clock generator providing a plurality of system clocks, wherein one of the system clocks is the operating frequency of CPU, the panel device comprising:

an adjustment unit having a plurality of adjustment stages for increasing or decreasing the operating frequency of CPU;

a display module for showing the system information; and

a microprocessor interconnecting the adjustment unit and the display module with CPU, the microprocessor being capable of adjusting the operating frequency of CPU in response to an adjustment done by the adjustment unit;

wherein the microprocessor issues an interrupt signal to CPU for interrupting CPU so as to control the system clock generator to modify the operating frequency of CPU via BIOS and SM bus, and the microprocessor also issues a service request to the computer to request the system information and then displays the system information on the display module.

2. The panel device as claimed in claim 1, wherein the display module comprises an operating frequency indicator for showing the operating frequency of CPU.

3. The panel device as claimed in claim 1, wherein the system information includes a CPU temperature, a system temperature, a motherboard status, a memory status, a hard disk status, and a CD-ROM status, and wherein the display module comprises a plurality of display units for showing the CPU temperature, the system temperature, the motherboard status, the memory status, the hard disk status, and the CD-ROM status respectively.

4. The panel device as claimed in claim 1, wherein the display module is LED type.

5. The panel device as claimed in claim 1, wherein the display module is LCD type.

6. The panel device as claimed in claim 1, wherein the computer further comprises a plurality of operating elements and the display module comprises a call-help indicator that is lit as activated by the microprocessor if at least one of the operating elements is malfunctioned.

7. The panel device as claimed in claim 6, wherein the operating elements of the computer comprise a motherboard, a hard disk, a CD-ROM, and a memory.

8. The panel device as claimed in claim 6, further comprising a buzzer for making a warning sound as activated by the microprocessor if one of the operating elements is malfunctioned.

9. The panel device as claimed in claim 3, wherein the display units comprise a CPU temperature indicator and a system temperature indicator for showing the CPU temperature and the system temperature respectively, and wherein each of the CPU temperature indicator and the system temperature indicator comprises a green LED being lit for representing a normal value of temperature, a yellow LED being lit for representing a relatively high value of temperature, and a red LED being lit for representing an over heat of temperature.

10. The panel device as claimed in claim 9, further comprising a fan being activated by the microprocessor for cooling the computer if the yellow LED is lit.

11. The panel device as claimed in claim 9, wherein in response to a lighting of the red LED for a predetermined period of time, the microprocessor issues a shut down signal to CPU for automatically turning off the computer.
