I have a new Dell R710 with a H700+BBU controller that is not charging. Last week when I was looking at performance stats (and trying to figure out why write policy had changed from write-back to write-through) I realized the BBU was not charged. The overall stats available through MegaCli appear to indicate the BBU is OK but it wont charge. I kicked off a manual learn cycle, waited a couple days, reseated the BBU, and nothing seems to get the BBU to a charging or charged state.

Any help is much appreciated.
