Clearing the CMOS will reset the password...
Take the button cell battery out for a few minutes, put it back in, and all settings, including the password, should go back to defaults.
Unfortunately it looks like your BIOS battery is under the keyboard...
Dell has got what looks like decent directions here, for getting at it:

It is one of the newer laptops and taking out the cmos battery doesn't necessarily help, you have to take out the battery and the power cord, access the bios chip and short two of the connectors (try googling appropriate search words using some of this content for pictures of the two contacts) with a metal tweezer or something similar, be careful not to join the wrong ones! and put the power cord in and switch it on while the two connectors are joined, and that should do it. it best not be stolen!!!

Need to locate the jumpers on the motherboard of dell latitude d420 notebook to reset os password


I'm not sure the d420 has a jumper for BIOS reset on the motherboard. I think you will need to remove the small CMOS battery under the keyboard (for around 15 minutes) to reset the BIOS password and settings.

I just bought a used dell latitude d420 and its locked and the person forgot the password how do i unlock it


I am afraid that such kind off issues could only be solved by motherboard replacement, unless you can contact your laptop's manufacturer support with a proof of ownership of this notebook.

There is also this service which can help you crack the BIOS password:

Bios password forget


Ok, let's take a look at this;

Under the keyboard you will find the cmos battery; you will need to remove this to set the factory defaults.

Do this at your own risk, it can be tricky sometimes

Before you start

Remove keyboard

Remove cmos battery

http://www.support.dell.com/support/edocs/systems/latd430/en/SM/coinbatt.htm#wp1123951


Leave it out for 15 mins.

It will work.

Pls how do i unlock my dell latitude d420 bios password


Dell stores its password in a special security chip which is activated only during boot time. So you cannot use any software to unlock it. Also there is no jumper by which you can clear the password. There are few password recovery services which charges about $100. I am trying to find a solution. If you can wait for a couple of days then I think I will be able to tell you something usefull.

Did you contact DELL. As long as you have the police report, they should be allowed to help you. That is a security issue. We can not tell you that because you could be someone with a stolen laptop. We have no way of knowing this. You would not want us to explain to someone how to break into your laptop would you?
