Dell C600 Bios Password

I have a customer that we sold a Dell C600 to. He let his son play with it and a Bios Password was installed and now customer can't get into it and kid doesn't know it.
The Service Tag # is
6L5G501
If someone knows a standard password that will get back into the bios without having to get someone to replace the bios chip.

Thanks,
Rob
The client uses this for business so your help is appreciated.

call dell, as long as you can verify ownership of the notebook, they will give you the master password (I don't know any, as they keep them away from the frontline techs, they only let the L2, managers, etc see the list)

remove the CMOS/BIOS battery and any form of power from the system for about an hour and put it back together again.  you should get an error about CMOS/BIOS Default being loaded ---> good to go

I would NOT recommend pulling the bios battery on a laptop that doc cashcomp provided is for desktop systems not laptops and i have never seen pulling the cmos battery on a laptop reset the bios password (most of the time it ends up badly for the motherboard because its sodered on). If you try to remove the cmos battery from this dell laptop you will most likely end up damaging the motherboard. I agree with what Tfjeff said you need to call Dell and get the master password for this system because that is the ONLY way to get the bios password reset on any dell laptop.

in modern laptops, the bios password is stored in a security chip, so clearing the bios will not help.
you really should contact Dell, and give proof of ownership. It may cost you though.

One of the Dell backdoor passwords is Dell

sorry guys.  I just put the SERVICE TAG and input it into  Dell's website and it came up as a dimension 4100.  figured he was in the wrong topic area.  Gave a link to Dell's site that dealt specifically with that unit.  Cut & Paste works good but only if the original information is correct.

my bad,

Yes the customer gave me the wrong ST number, however he did Call Dell and give them a copy of my receipt and they got him going.

Thanks tfjeff

I should have thought of that.
