Troubleshooting: Common computer motherboard fault code meanings When the computer motherboard fails, it will remind the user through a series of fault codes. These codes are usually displayed on the motherboard's LED lights or in the BIOS settings, helping users quickly identify the source of the fault. This article is brought to you by Baicao, the editor of PHP, which sorts out common computer motherboard fault codes and their meanings to guide you in quickly solving computer problems. Continue reading for details below to learn about these fault codes so that you can promptly handle motherboard failures and restore normal operation of your computer.
1. From a series of codes (excluding "00" and "FF") to "FF" or "00", the motherboard self-test has passed, OK.
2. If "00" is output and the code does not change, the motherboard is not running. Check whether the CPU is broken, the CPU jumper, or whether the CPU settings are correct, whether the power supply is normal, and whether there is mold on the motherboard battery, etc.?
3 . If you set the CMOS to not prompt errors, when encountering a non-fatal fault, the diagnostic card will not stop and continue to go back to "00". The solution is to change the CMOS setting to prompt all errors and then turn on the computer. , if there is a non-fatal fault at this time, it will stop and then troubleshoot according to the code.
In the process of daily use of computers, we sometimes encounter various fault problems. These problems are often accompanied by specific error codes that may seem meaningless to the average user. Next, we will analyze some common computer fault codes and explore ways to solve these problems.
Blue Screen of Death is a common fault prompt in Windows systems. It is usually accompanied by specific error codes, such as 0x0000007B, 0x00000024, etc. These codes usually indicate different types of system errors, which can be caused by hardware failures, driver issues, or software conflicts. To solve these problems, we can try to update drivers, repair system files, or troubleshoot hardware problems.
When the network connection fails, we sometimes see error codes such as "DNS_PROBE_FINISHED_NXDOMAIN", "ERR_CONNECTION_TIMED_OUT" and so on. These codes imply problems with network connection or access to specific websites, which may be caused by DNS resolution failure, incorrect network settings, or network latency. We can solve these problems by clearing the DNS cache, changing the DNS server, or checking the network equipment.
Many applications will generate error codes when running, such as "0xc000007b", "0xc0000005", etc. These codes often indicate corrupted program files, operating system permission issues, or memory access errors. To resolve these issues, we can try reinstalling the application, repairing operating system permissions, or performing a memory check.
Error codes caused by hardware faults are often hexadecimal numbers, such as "0x0000003B", "0x802B000A", etc. These codes may indicate hardware failure, such as memory module problems, hard drive failure, or other hardware damage. When facing these problems, we recommend performing hardware diagnosis or seeking professional hardware repair support.
In the daily use of computers, it is common to encounter fault codes, but we do not need to panic too much. By understanding the meaning of these codes, we can quickly locate the problem and take effective solutions. I hope this article can help you better understand computer fault codes and successfully solve computer fault problems.

1. Code 11: Battery circuit is disconnected.
This code indicates that the QF1 switch on the battery circuit is disconnected or the battery circuit is disconnected. This error can be detected by measuring the voltage on the QF1 line. When the UPS is on and the charger is stopped, you can measure the battery voltage at this time.
Battery voltage
2. Code 12: The battery needs to be tested.
This code will be displayed when the battery life recorded in the battery life counter has ended, the automatic battery test (open circuit voltage test) has failed, or the automatic battery test (partial discharge test) has failed.
This error is easy to remember and can only be solved by "Reinitialize" in the "Command" menu of "Soft-tunor".
Answer formula 1: There are many common fault codes for washing machines. Mainly because the washing machine has a long service life, it is inevitable that various faults will occur during use. When a fault occurs, the washing machine will generate different fault code prompts. Here are several common washing machine fault codes and their meanings: 1. E1: Indicates a high water level fault, which is caused by poor drainage of the washing machine. 2. E2: Indicates that the heater is faulty and you need to check whether the heater is damaged. 3. E5: Indicates that the water level sensor is abnormal, and it is necessary to check whether the sensor is faulty or whether the circuit is damaged. 4. E6: Indicates that the door lock signal is abnormal. It is necessary to check whether the door lock sensor is faulty or whether the door lock control circuit is damaged. To sum up, the common fault codes of washing machines mainly include the above types. When the fault code prompts, it is necessary to repair or replace the corresponding parts according to the specific cause of the fault.
