Dell Support: Disabling a forgotten password on Dell 400SC
I own six 400SCs and have never seen a request for a BIOS Password, so I doubt there's a "Default Value".
I'd change out the battery, use the password jumper as described above, and see what happens.
Don't forget that 30-50% of all Dell 400SCs have defective power capacitors on the motherboard, which will result in bulging/leakage, and likely eventual failure of the motherboard. First signs are self-reboots and difficulty starting up the server. Eventually it won't start up at all.
