i also have W2003, but why it doesnt work on 2003. Did you try to fix it? Cause when I downloaded the firmware from HP.com I chose it for 2003 server. I also heard that some firmwares may not correctly work on P410i. Is version 6.00 OK with this controller?
And I should look at the date on battery. Does it show the production date only or smth like best before too?
It says Battery failed and should be replaced on POST and in ACU, but maybe its because of the firmware?
Thanks...
