In essence, industrial computers are not much different from ordinary computers, and the power supply and motherboard are more stable than ordinary computers. This is because industrial occasions have higher requirements than ordinary commercial occasions, so industrial computers will encounter many problems, such as black screen and inability to start. So what are the most easily solved faults of industrial computers?

1. Display faults

1. There is a display when the computer is turned on, but the screen is very dark, and there is no change after debugging with the brightness adjustment function key;

2. The turned-on touch screen is white (no text image) or has flowers, but the display is normal;

3. There are horizontal or vertical bright lines and stripes on the touch screen;

4. The startup screen appears black, but the image of the external display is normal;

5. It cannot be touched or touched off.

Solution: If the display fault is normal, you can replace the LCD or touch panel to solve the problem.

2. Repair common hard disk faults

1. The hard disk runs very slowly and may freeze;

2. When starting the industrial computer, the screen prompts that the hard disk cannot be found;

3. The hard disk makes abnormal noises and the system cannot start;

4. The hard disk circuit board burns or smokes;

5. Data recovery such as wrong deletion and wrong formatting, wrong cloning and wrong partitioning, virus invasion, etc.

Solution: Just back up the data and reinstall the system.

2. Common faults of industrial computer keyboard

1. The keyboard single key does not respond;

2. The keyboard is flooded;

3. The keyboard will automatically repeat the key.

Solution: You can try another keyboard.

4. Industrial computer battery failure

1. The battery cannot be charged;

2. The industrial computer powered by the battery cannot be turned on;

3. The battery can be charged, but the discharge time is extremely fast.

Solution: It is recommended to replace the battery, or there may be a problem with the motherboard.
