Check the power supply: confirm whether the power cord of the industrial computer is connected correctly and whether the power socket has electricity. Use multimeter to check whether the power supply outputs normal voltage 12V, 5V.
Check the display problem: if other parts of the industrial computer are normal, but the display is not displayed, it may be that the display signal output is set incorrectly or the VGA cable is faulty. Try clearing CMOS to restore the default settings, or set the display output to VGA in the BIOS.
Check the hardware connection: Open the case cover and check whether the memory module is installed correctly or loosely. Reseating or replacing the memory module may help solve the problem.
System failure: If the above hardware checks are correct, it may be that the operating system is damaged. You can try to start the industrial computer with the startup disk, back up the data and reinstall the operating system.
BIOS check: Press the Delete key to enter the BIOS settings when booting, and check whether the hard disk parameters are correct, so as to ensure that there is no situation that the boot cannot be started due to incorrect BIOS settings.
Hardware failure: If the above steps fail to solve the problem, it may be that the motherboard or other key hardware components have failed. If there is an alarm sound, further analyze the problem according to the different characteristics of the sound.
Professional maintenance: If the self-inspection maintenance is ineffective, it is recommended to contact Advantech technical support or professional maintenance personnel for inspection and maintenance.
When doing the above operations, please be sure to follow the electrical safety specifications and consider the warranty status of computer equipment. If the equipment is still under warranty, it is recommended to contact the manufacturer directly for maintenance, so as to avoid unnecessary losses caused by self-maintenance.
