In fact, there is not much difference between the industrial computer and the ordinary computer, but the power supply and motherboard are nominally more stable and reliable than the ordinary computer, after all, the requirements of industrial sites are a little higher than that of civilian computers, and the problems encountered by the so-called industrial computer are similar to those of ordinary computers, such as the black screen of the crash and the problem that cannot be started.
1. Display problems
1. There is a display when the industrial computer is turned on, but the screen is very dark, and there is no change after debugging with the brightness function key.
2. The white screen of the contact screen (no text image) of the industrial computer may be blurry, but the external display is normal.
3. There are horizontal or longitudinal bright lines and bright bands on the contact screen of the industrial computer.
4. The boot screen of the industrial computer presents a black screen, but the image of the external monitor is normal.
5. Can't touch or contact offset
These problems can be solved by replacing the liquid crystal or contact plate.
2. Repair common problems of hard disks
1. The hard disk of the industrial computer is very slow when running the program, and it is also accompanied by a crash.
2. The time-division screen of the industrial computer starts and prompts that the hard disk cannot be found.
3. An abnormal rattling sound is announced on the hard disk, and the system cannot be started.
4. The circuit board of the hard disk is burned or smoked.
5. Accidental deletion and formatting, accidental cloning and mispartitioning, and recovery of data such as virus invasion
In this case, it is good to back up the data and reinstall the system.
3. Common problems in industrial computer keyboards
1. A key of the keyboard of the industrial computer is out of order.
2. The keyboard of the industrial computer is flooded,
3. The keyboard of the industrial computer automatically repeats the keys.
Fourth, the industrial computer battery is abnormal
1. The battery of the industrial computer cannot be charged.
2. The industrial computer using the battery cannot be turned on.
3. The battery of the industrial computer can be charged, but the discharge time is very short.

The difference between serial ports RS-232, 422, and 485 on industrial motherboards
Serial port is a very common device communication protocol on industrial motherboards, and most industrial motherboards contain more than two serial ports based on RS-232. The serial port sends and receives bytes on a bit-by-bit basis, which is slower than parallel communication on a byte-by-byte basis, but the serial port can be used in the use of a single wire.

Key points for the selection of industrial motherboards - EVOC
1. Production process
When purchasing an industrial motherboard, you should first observe the manufacturing process of the industrial motherboard. Detect the manufacturing process of the industrial motherboard to see whether the workmanship of the motherboard is precise, such as whether the number of layers of the circuit board is a multi-layer board (preferably more than 6 layers), whether the joints of each solder joint and wave solder joint are working.
