In fact, there is not much difference between the industrial computer and the general computer, but the power supply and motherboard are nominally more stable and reliable than the general computer, after all, the requirements of industrial sites are a little higher than that of civil ones, and the problems encountered by the so-called industrial computer are similar to those of the general computer, such as the problem that the black screen of the dead machine cannot be started.
1. Manifestation problems
1. The industrial computer is displayed when it is turned on, but the screen is very dark, and there is no change after debugging with the brightness function button.
2. The white screen of the contact screen (no text and pictures) of the industrial computer may be blurred, 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 picture of the external display is normal.
5. If you can't contact or contact offset, you can generally replace the liquid crystal or contact plate to solve the problem.
2. Repair common faults 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. In the case of data recovery such as accidental deletion and formatting, accidental cloning and wrong partitioning, and virus invasion, it is good to back up the data and reinstall the system.
3. Common fault phenomena of 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.

Fanless is structurally different from traditional industrial computers - EVOC
The traditional industrial computer uses a combination of 4U and other types of cold-rolled plate chassis + gold finger motherboard (full-length or half-length card) + base plate + high-power power supply.
There are a number of unstable elements to such a structure:
1. If the CPU card is inserted into the baseboard, there will be a bad touch phenomenon, such as vibration.
