Battery sensor error message description

Error messages can be generated by the following battery sensors.

Note: The "x" in the code represents the actual error condition.

Platform and sensor code	Sensor description
ENV001542	Battery Low (NVRAM battery sensor)
ENV00153x	Real time clock battery (RTC_batt).

The following table lists the error messages that can be generated by the real time clock sensor on the motherboard. The corrective action for this error message grouping is below the error message description.

Note: "[d]" in the sample error message represents the status of the sensor monitoring the real time clock battery on the motherboard.

If "x" is...	Sample error message	Description
1	[d] does not read	[d] sensor is not responding.
2	[d] is in bad state	[d] sensor is not functioning.
3	[d] expected interrupt-to-bad did not occur	The interrupt indicating that [d] sensor is malfunctioning failed to occur.
4	[d] expected interrupt-to-normal did not occur	The interrupt indicating that [d] sensor is back to normal failed to occur.

Corrective action

The following table lists the corrective action that can be taken for error messages generated by the battery sensors.
