Did you remove the CMOS-battery, or just the DC-accu? The CMOS-battery is a small coin-cell battery that enables the BIOS to store settings while the computer is powered off.
This battery can be found beneath the keyboard as shown in the dell service manual.

You could also take a look here, if you don't want to open your laptop, or if removing the battery doesn't work:

On the bottom of the page is a list of some programs that might be able to restore or read the password.

Cant remember administrater password.wont let me delete files without it.


Derek, You are in trouble if you have lost the admin password. I would suggest that you take a backup of your data and reinstall Windows on your PC/laptop. and give such passwd which you cant forget. Can you believe 30% of the visitors to this site are forgetters of passwords. And we all must use them.

Can't boot and forgot bios password on ibm r50e


Yikes. You've set a password on the BIOS and don't remember it?

Well, most manufacturers set a "backdoor" password on the bios that will allow you to get in. It used to be the backdoor PW for IBM was "merlin" but that may no longer be the case. If you absolutely cannot get in, then your option is to open the case to the laptop and disconnect the CMOS battery for about 15 seconds and then reconnect it. That will clear the CMOS to the factory defaults.

I wish you well with this.
Thanks for using FixYa!!
