Industrial computers are mainly used in various industrial sites related to production such as continuous production, intermittent production and batch processing, and are characterized by reliability and stability, and the probability of product problems is low. In the face of different industrial sites, the industrial computer may be in a very complex environment, such as dust, high-frequency oscillation, ultra-high and low temperature, etc., which can cause harm to the industrial computer, coupled with human factors, the industrial computer can not be used normally. Now for some common use environments, when the industrial computer cannot be started, the general judgment process:
The phenomenon that the IPC cannot be started may be as follows:
1. There is no repercussion when the industrial computer is turned on, the indicator light of the industrial motherboard is not lit, and the power fan does not rotate
1. First of all, you should check whether the power supply of the industrial computer is normal.
2. If the AC input is normal, you should consider whether there is a problem with the power supply of the industrial computer. At this moment, you should remove the ATX power supply interface and the large 4P port of CPU power supply, and use tweezers or cables to short the green and black wires of the ATX power supply interface. See if the power supply can work normally at the moment, if the power fan can work normally at the moment, it means that there is no problem with the power supply itself, and the condition of the industrial motherboard should be considered at this moment. It is necessary to remove the excess cards and USB devices on the industrial motherboard, leaving only the most basic equipment to see if the industrial computer can run. If the IPC still cannot operate normally, the industrial motherboard should be removed to check whether there is a short circuit and burnout.
2. After the industrial computer is turned on, the fan works normally, but it cannot be started normally
1. BIOS alarm when the industrial computer is turned on, this kind of situation is the most common situation, and the specific situation can be handled with reference to the meaning of various types of BIOS alarm sounds.
2. There is no alarm sound when the industrial computer is turned on, and the CPU fan turns for a while and stops, and so on. Consider that there is a problem powering the CPU or that the CPU is loose.
3. When the IPC is turned on, the display always stops at the initial BIOS initialization boot interface, and the next step cannot be followed. At this moment, take a look at the peripherals, whether there is a USB flash drive and other USB devices, mostly BIOS problems, dial the relevant USB devices and restart the industrial computer can run normally, advocate updating the BIOS to correct this problem.
4. If there is no alarm sound after the industrial computer is turned on, and the CPU fan works normally, but it cannot be initialized normally, the minimum system method should still be used to analyze it to see if there is an attachment on the industrial motherboard that causes a short circuit or the motherboard is burned out.
