when i start it a screen appears of inspiron with f2 setup nd f12setup at bottom and after that a black screens appears with a blue box in the middle of screen which asks "enter system password"! i am helpless:(

I have a Poweredge 2950 perc 6i raid 5 array, with 5 drive in the array and 1 hot swap. Drive 0-3 still show as online. Drive 4 failed last night and then the hotswap failed. After reboot both drives are listed as missing and the VD is offline.

1. I had to replace the old original batterie. I bought the same original Dell battery, but i still get the message that the battery has reached end of lifetime and should be replaced. (That is why I replaced it in the first place...) Is there a way to reset the message? 2.
