Industrial computers (IPCs) are the core of industrial automation systems, running 24/7 in harsh industrial environments. Proper daily maintenance extends their service life, reduces failures, and avoids costly downtime. This guide covers practical maintenance methods and quick fault solutions for industrial operators.

Part 1: Daily Maintenance of Industrial Computers

IPC daily maintenance is simple; regular checks improve stability. Key points are as follows:

1. Keep the Device Clean and Dry
Clean IPC surfaces and ventilation holes with a soft dry cloth every 1-2 weeks to avoid dust-caused overheating. Do not use water or chemical cleaners. In humid environments, check for condensation and ensure good ventilation.

2. Ensure Stable Power Supply
Use a matched power supply; install a voltage stabilizer for unstable grids. Monthly check power cables/plugs for damage, aging or looseness, and replace them promptly to avoid hazards.

3. Regularly Back Up Data and Update Firmware
Back up key data (system configs, production data) weekly with industrial-grade storage. Follow supplier guidelines to update firmware/software; avoid unofficial updates to prevent malfunctions.

4. Monitor Temperature and Heat Dissipation
Maintain IPC operating temperature (-20°C-60°C). Keep fanless IPC heat dissipation surfaces unblocked; clean fan-equipped IPCs monthly. Avoid installing near high-temperature equipment. For fan-equipped models, check if the fan is running normally every month, and clean the fan and heat sink if there is dust accumulation.

Part 2: Common IPC Faults and Quick Troubleshooting

1. Hard Drive Not Detected
1.1.Check if the motherboard requires jumper settings or hardware changes (please refer to the motherboard manual for details).
1.2.Verify that the hard drive signal is compatible with the motherboard and that it is not connected to the wrong position.
1.3.Check if the hard drive can be detected in the SATA settings of the BIOS (for motherboards that do not support legacy mode booting, the hard drive boot information will only be visible in BOOT after the UEFI system is properly installed).
1.4.Confirm that the SATA power cable is compatible with the motherboard, and check if the SATA data cable and the hard drive itself are damaged.

2. Blue Screen After Entering System
2.1.Check if the system mode and hard drive mode settings in BIOS are correct before installing the system.
2.2.Check if the memory modules and external devices are lost; try removing newly installed hardware and replacing the memory.
2.3.Confirm if the motherboard driver is officially released; try uninstalling the driver, software, or reinstalling the system.
2.4.Verify if there is noise in the output voltage and current of the power supply, and if the peripherals are properly grounded.
2.5.Confirm if the operating system is normally installed on the hard drive, if there is a virus infection, and if the system is installed on the used motherboard.
2.6.Check if the hard drive is damaged; remove the peripherals to troubleshoot whether the problem is caused by the peripherals.

3. Failure to Automatically Power On
3.1.Make sure residual power in the power supply has been fully discharged after unplugging the power cord; plugging in power before discharge may cause failure to power on.
3.2.Check that the power-on function is not enabled in both BIOS settings and hardware jumpers at the same time — only one of the two can be selected.
3.3.Verify if the onboard CMOS battery is low or depleted.

4. System Freeze & Screen Artifacts
4.1.Check if RAM modules and external devices are loose. Try removing newly installed hardware and replace RAM or CPU if necessary.
4.2.Confirm that motherboard drivers are officially released versions. Try uninstalling drivers or problematic software or reinstalling the operating system.
4.3.Verify that the OS is properly installed on the hard drive, check for virus infections, and ensure the system is installed on the current motherboard.
4.4.Inspect the hard drive for damage. Disconnect external peripherals to determine if the issue is caused by external devices.
4.5.Troubleshot potential damage to the system, power supply, RAM, and CPU.

In summary, IPC maintenance focuses on prevention, while fault troubleshooting emphasizes quick positioning. Following the above tips can reduce failures, extend service life, and ensure stable industrial production. For complex faults, contact the supplier’s technical support promptly.
