1. Check the CMOS battery voltage

First, confirm whether the CMOS battery voltage is normal. Use a multimeter or voltmeter to measure the voltage of the CMOS battery. Under normal circumstances, it should be around 3V. If the voltage is lower than 2.9V, it is recommended to replace the battery, remove the low-voltage battery, and replace it with a new 3V battery.

2. Set the BIOS time and date

After replacing the battery, enter the BIOS setup interface, find the time and date setting option in the BIOS setup interface, and adjust it to the current accurate time and date, save the settings and exit the BIOS interface, restart the industrial computer, and check if there is still an error message of "CMOS Settings Wrong".

3. Flash BIOS

If the above steps still cannot solve the problem, there may be a problem with the BIOS itself. In this case, you can consider flashing the BIOS to fix it. (But please note that flashing the BIOS is a sensitive operation. If you are not familiar with this process, it is recommended to seek professional technical support.)

The steps for flashing the BIOS are as follows:
