I keep getting alerts on one of our customers systems that the battery for the PERC controller needs to be re-calibrated. I have looked all through-out the web and couldn't find anything on this, and IBM/Lenovo was no help, as they can't do anything unless it's under warranty or billed for service. All I'm looking for is documentation on how to recalibrate the battery so we stop getting these continuous alerts. Anyone know any info on this?
