Industrial touch panel computers: Common 23 failure causes and solutions
The long-term use of industrial computers inevitably leads to problems. This does not mean that the products manufactured by the manufacturer have any quality issues. No matter when they are used, there will always be some minor problems.

Industrial computer troubleshooting methods:
- After powering on, the motherboard can work normally. The BIOS detects the keyboard components and reports keyboard errors. First, check if the keyboard lock is locked, then unlock the keyboard. If not, check the connections between the motherboard and the baseboard, as well as whether the keyboard and mouse are connected correctly.
- After powering on, other components are working normally. The floppy drive read indicator light is always on. The floppy drive cannot be used. It should be that the floppy drive data cable is reversed.
- After powering on, the power indicator light on the back panel will turn off and cannot be powered on.
First, check if there are any foreign objects in the case, such as screws, causing a short circuit. Next, check if the power cable is reversed, causing a ground short circuit. Use the replacement method again, replace the power supply, check if there is a problem with the power supply, and replace the floor to check if there is a problem with the floor. - Before installing the hard drive in the industrial computer, it can start. After installing the hard drive, it is found that it cannot start?
Please first check if the hard drive data cable is reversed. - Are the mouse and keyboard not usable?
Check the dice, see if it is dedicated. If not, reverse the keyboard and mouse usage. - After powering on the industrial computer, the power is working normally. Is the motherboard not reflecting?
First, remove the peripheral cards and connected devices, see if it can start? If not, you can remove the memory and see if this is an alarm? Then check the CPU’s operation, is it normal? Finally, replace the motherboard and check if it is normal. - When installing the operating system and loading the sound card driver, it crashes?
First, the type of the sound card is not selected correctly, then select the correct type before installation. Second, the selected sound card conflicts with other devices (including network card, graphics card, motherboard). - After powering on the machine, it does not start and can hear continuous alarm sounds?
Based on the alarm sound, it can be determined that this is a memory problem. Open the machine to check if the memory is in good contact, or replace the memory slot for testing. Finally, replace the memory and see if there is a memory problem. - After loading the sound card driver, the running speed is slow or the sound is too small?
Generally, the sound card conflicts with the motherboard. - When installing the graphics card, the driver installation is correct, but there is no image display or no color display?
The default graphics card system defaults to “ntfc”, it needs to be set to “PAL” format! - When the client program is running, there is an unexplainable restart phenomenon?
The client software is related to the compatibility of the motherboard. After a comprehensive check, if the reason still cannot be found, please replace the motherboard and try again. twelve. When the industrial computer is operating normally, it will restart when there is vibration.
There is a fault in the power connection, or the connection between the motherboard and the floor is poor (which connection of the ATX function has been realized)? - When the operating system is GHOST, are the partitions of the original disk and the newly formatted disk inconsistent?
The mode of the hard disk is inconsistent. It should be set to LBA mode. fourteen. The industrial computer is functioning normally in the company. After being used by the customer, it won’t display anything.
Usually, the resolution setting is too high and cannot display the customer’s display. So this phenomenon is a black screen, but there is a normal alarm sound. 15. Can I use a USB flash drive under DOS?
It depends on the support of the motherboard. Some motherboards can support it. Most motherboards do not support it. - Can a USB hard drive or USB flash drive be used as a boot disk?
It depends on the support of the motherboard. Most new motherboards can support it, while some older models may not. - Can ordinary hard drive interfaces on the motherboard be used for 2.5-inch small hard drives?
Yes, but you need to do it yourself. There is no standard procedure. - Can all PCI cards in industrial computers not be used?
Wipe the PCI gold fingers of the motherboard with rubber or replace the motherboard slot. - Can serial lines from different manufacturers be interchanged?
This depends on whether the definitions of the serial ports on the motherboards are consistent. If they are consistent, they can be interchanged. 20. Can the keyboard port on the motherboard be directly connected to the mouse?
No. - Can the current ATX case implement the AT function?
Yes, but on this wide case, an AT switch is necessary. You need to connect the wires to the switch. - Can the industrial control mode PCI card not be used?
Check if the gold fingers of the PCI card are dirty. If they are not clean, use a eraser. - Can the industrial computer with ATX power supply achieve “sequential startup”?
This is related to the motherboard. If the motherboard supports it, then it can.
