Common faults and solutions of industrial computer - EVOC

With the continuous development of industrial computer technology, industrial computers have been widely used in industrial production. Therefore, we need to understand the causes of industrial computer failures and how to deal with them. Below, we give corresponding solutions to the common faults of industrial computers.

Common faults and solutions of industrial computer - EVOC

1. After the industrial computer is powered on, the power supply works normally, and the motherboard has no response?

Remove the peripheral card and connected device first, and see if it can be activated? If there is no response, remove the memory to see if there is an alarm? Then see if the CPU is working properly? Eventually, replace the motherboard and see if it's working.

2. Can the motherboard work normally after booting up, and the BIOS detects the keyboard part and reports the keyboard error?

First, check to see if the keypad lock is locked, then loosen it. If not, check whether the motherboard and backplane are connected correctly, and the keyboard and mouse are connected correctly.

3. After powering on, the power indicator on the bottom plate will turn off after turning on, so it can't be powered on?

First, check whether there is a short circuit caused by foreign objects in the chassis. Second, check to see if the power cord is reversed, resulting in a short circuit to ground. Again, replace the power supply, motherboard, backplane, and other devices.

4. After booting up, I hear the motherboard self-test sound but it is not displayed on the monitor:

1. Check whether the monitor is connected to the host normally;

2. Eradicate the CMOS (the setting may be at fault) or replace the BIOS;

3. Replace the CPU board (motherboard integrated graphics card) or monitor.

5. The start-up time of the industrial computer is too long:

1. Run the disk defragmenter to remove the fragmentation;

2. Close the auto-start items of the system boot file;

3. Run the disk cleaner program to eradicate junk files;

4. Adjust the network settings.

6. After booting up, it is found that there is a big difference between the memory and the actual memory:

1. Check whether the motherboard memory is shared with the motherboard memory, so that part of it will be separated from the memory as memory;

2. Check whether the memory is small-grained memory, because some old chips do not support large-grained memory, only half of the capacity will be displayed after plugging in;

3. A very small number of motherboards use dedicated CPUs, which occupy part of the memory as an instruction decoder for CPU instruction set conversion, resulting in inconsistent memory capacity.

7. Turn on the power and the industrial computer has no response:

1. Check whether the power socket is powered on and whether the connection with the industrial computer is normal;

2. After turning on the machine, check whether the power supply fan is rolling and whether the connection between the monitor and the host is normal;

3. Whether it will alarm when you unplug the memory and turn it on;

4. Replace the CPU or motherboard.
