Hello, I have just converted an old PC into a NAS using FreeNAS, it works fine but every time it boots it reports cmos battery low. Obviously I have replaced the battery (several times). The bios hardware diagnostics show the battery voltage at about 3.6 volts which is correct. Any suggestions?

Only that hardware does wear out eventually. If the sensor is failing or the voltage regulation or whatever the only real option will be replacing the board (or living with the error).
