Multi-functional computer fault diagnosis instrument

Abstract

The invention discloses a multi-functional computer fault diagnosis instrument. The multi-functional computer fault diagnosis instrument comprises a central processing unit, an LED display unit, a VGA interface unit, a RJ 45 interface unit, an audio power amplifier module, a BNC interface unit, a USB&PS / 2 interface unit, an LED flashlight unit, a voltage comparator unit, a PCI gold finger interface, a keyboard, a lithium battery power supply unit, an electric leakage detection gold finger, a DC input interface, a power module, a wireless & infrared receiver, an audio input interface, an audio output interface, a loudspeaker, AUDIO row needle interfaces and 2P row needle interfaces. The multi-functional computer fault diagnosis instrument can not only detect a computer host fault, but also can detect whether a computer display, a sound, an earphone, the keyboard and a reticle are good or not, detect whether a computer microphone, a computer sound card, a monitoring camera and the wireless & infrared remote controller output signals or not and detect whether a computer case shell has electrical leakage or not, and the computer maintenance work becomes more relaxing and rapid.

Description

(1) Technical field [0001] The invention relates to a computer fault diagnosis device, in particular to a multifunctional computer fault diagnosis device. (2) Background technology [0002] The main tool for diagnosing computer faults at present is the main board fault diagnosis card of the prior art, but its function is less, can only detect computer main board fault, and the computer fault range is wider, especially desktop computer, also has external equipment fault, as display , audio, microphone, earphone, keyboard, network cable, and even video monitoring system, etc., it cannot be detected by the motherboard fault diagnosis card of these prior art. (3) Contents of the invention [0003] In order to solve the above problems, it is necessary to provide a multifunctional detection device that can integrate multiple detection functions into one, so that the computer maintenance work becomes easier and faster. [0004] A multifunctional computer fault diagnosis instrume...
