25A80xxx NVRAM Note: Errors reported against NVRAM
can be caused by low Battery voltage
and (more rarely) power outages that
occur during normal system usage.
With the exception of the 25A80000
error, these errors are warnings that
the NVRAM data content had to be
re-established and do not require any
FRU replacement unless the error is
persistent. When one of these errors
occurs, any system customization (eg.
boot device list) information has been
lost, the system may need to be
reconfigured.
If the error is persistent, replace the
battery.
If the error is persistent after battery
replacement, or the error code is
25A80000, replace the system board.
