How to self-check if the industrial computer cannot be started?

Industrial computers are mainly used in various industrial sites related to production and manufacturing, such as continuous production, intermittent manufacturing, and batch processing. They are characterized by reliability and stability, and the possibility of product problems is very low. However, in the face of different industrial sites, the industrial computer may be in a very complex environment, such as dust, high frequency vibration, ultra-high and low temperature, etc., which may damage the industrial control computer. In addition, human factors make the industrial control computer unusable. Now for some common use environments, the industrial computer cannot be started. What are the general judgment steps? Shen Zhen ZeChuang Weiye Technology Co.,Ltd-industrial computer manufacturers share:

The possible phenomena that the industrial computer cannot be started include:

1.) When the industrial computer is started, there is no response, the indicator of the industrial main board does not light up, and the power supply fan does not rotate

1. First, check whether the power supply of the industrial computer is normal.

2. If the AC input is normal, consider whether the power supply of the industrial computer is faulty. At this time, you should remove the ATX power interface and the large 4P interface powered by the central processing unit, and use tweezers or wires to short-circuit the green and black wires of the ATX power interface. See if the power supply can work normally at this time. If the power supply fan can work normally at this time, there is no problem with the power supply itself. At this time, the situation of industrial motherboards should be considered. It is necessary to remove all redundant card USB devices on the industrial motherboard, leaving only the most basic equipment to see if the industrial computer can run. If the industrial computer still does not work normally, the industrial motherboard should be removed to check if there is a short circuit or burnout.

2.)After the industrial computer is turned on, the fan runs normally, but cannot start normally

1. When the industrial computer is turned on, the basic input output system alarm will appear. This situation is the most common. The specific situation can be handled by referring to the meaning of the alarm sound of the basic input and output system of various models.

2. When the industrial computer is turned on, there is no alarm sound, the CPU fan rotates for a while, then stops, and repeats. Consider the power supply problem of the central processing unit or the loosening of the central processing unit.

3. When the industrial computer is started, the display screen always stays at the initial basic input output system initialization start interface, and cannot proceed to the next step. At this time, take a look at the peripheral part. Whether USB flash drives and other USB flash drives are inserted is mainly a basic input output system problem. When the related USB device is removed and restarted, the industrial computer can operate normally. It is recommended to update the basic input output system to fix this failure.

4. If there is no alarm sound after the industrial computer is turned on, and the CPU fan is operating normally but cannot be initialized normally, the minimum system method should be used to analyze whether there are accessories on the industrial motherboard that cause a short circuit or the motherboard burns out.
