How to accurately solve the common faults of industrial motherboards?

Industrial motherboards are motherboards used in industrial occasions. They can adapt to a wide temperature and wide pressure working environment, and can work under high load for a long time according to their needs. In addition, the industrial motherboard is specially designed to automatically restart the watchdog when encountering abnormal conditions such as downtime to ensure the high stability of the system in complex environments. According to the chip type, it can be divided into X86 industrial motherboard, ARM industrial motherboard, etc. So how to accurately solve the common faults of industrial motherboards?

1. Related to the industrial motherboard driver

If the driver of the industrial motherboard is lost, damaged, or repeatedly installed, it will cause the operating system to fail to boot or cause the operating system to work unstable. You can open "Control Panel - System - Device Manager" in turn to check whether the items in "System Devices" are not. There is a yellow exclamation mark or question mark. Delete all the items marked with yellow exclamation marks or question marks (operate in "safe mode"), reinstall the driver that comes with the industrial motherboard, and restart.

2. Poor contact, short circuit, etc.

The industrial motherboard has a larger area and is a place where there is a lot of dust. If dust causes poor contact between the slot and the board, you can dust the slot. If the contact is poor due to the oxidation of the socket pins, you can fold the white paper with hardness (the smooth surface is outward), insert it into the slot and wipe it back and forth. In addition, dust attached to the thermistor used to detect the temperature of the CPU in the CPU socket or used to monitor the temperature in the chassis on the industrial motherboard may cause the industrial motherboard to incorrectly recognize the temperature, thereby causing the problem of protective failure of the industrial motherboard. You also need to be careful when cleaning.

In addition, when disassembling the chassis, accidentally dropped conductive objects such as small screws may get stuck between the components of the industrial motherboard and cause a short circuit, which will cause a "protective fault". At the same time, check whether there are no small copper pillars used to support the motherboard between the industrial motherboard and the chassis bottom plate; whether the industrial motherboard is improperly installed or the chassis is deformed, so that the motherboard and the chassis are in direct contact, so that the power supply with short-circuit protection function automatically cuts off the power supply. .

3. Related to industrial motherboard batteries

When the hard disk cannot be found correctly when booting, the system time is incorrect after booting, and the CMOS settings cannot be saved, etc., you can first check whether the motherboard CMOS jumper is set to clear the "CLEAR" option (usually 2-3). , change the jumper to the "NORMAL" option (usually 1-2) and reset it. If it is not the CMOS jumper error, it is likely to be caused by the damage of the motherboard battery or insufficient battery voltage. Try another motherboard battery.

4. It is related to the failure of industrial motherboard capacitors

The aluminum electrolytic capacitor on the industrial motherboard (generally around the CPU socket) uses an electrolyte inside it. Due to the reasons of time, temperature, quality, etc., it will cause it to "age", which will lead to the anti-interference index of the industrial motherboard. The drop will affect the normal operation of the industrial computer. Buy a capacitor with the same capacity as the "aging", prepare the soldering iron, solder wire, and rosin, and replace the "aging" one. In addition, the loss of tools when disassembling and assembling the industrial computer may also accidentally smash the capacitor, which should also be checked and eliminated.
