Question about Dell Computers & Internet

Dell Latitude D620 BIOS password help!!! I bought a Dell D620 and I noticed that some BIOS features are password protected. The previous owner said he doesn't know anything about it, so I'm not sure what should I do now. Any ideas would be appreciated. The laptops service tag is 4YXMT2J-595B, if it's of any help.

    I have tried this in the past and tried it again now, but it does not solve the problem.

    Let me detail the problem: I can install the OS and use the computer, and I can view the BIOS settings, but I cannot edit them. I need the "master" password, which (from what I read on forums) is generated using the service tag I provided.

    In other posts on FixYa I saw experts that provided these passwords, but as they are attached to those users service tags are useless to me. I am waiting for one of those experts to help me too.

    Also advising me to buy 50$ worth of service/software to unlock my BIOS is not an option. I already paid FixYa for a premium response, so I'll wait just for that and hope it was worth my time.

    Removing the CMOS battery doesn't work. Tried it long before posting here.
    Also, I already have software that can remove/reset the BIOS password (for free), but as with any software there's a possibility it can brick my laptop. So I want to try the alternative before taking this risk.

    None of the bios tools from Ultimate Boot CD work for my laptop. Already tried it before posting on FixYa.

  • limpangel Nov 12, 2010

    My laptop is out of the warranty period so Dell support is not an option.

  • limpangel Nov 12, 2010

    Upgrading the firmware does not work. It says "Cannot run under a protected enviroment".

  • limpangel Nov 12, 2010

    I cannot, because my country is not supported. This laptop was bought outside of US. If Dell support was an option I wouldn't have come to FixYa.

Dell usually sets a default password as password or admin Try those first. If no luck go into the bios setup by continually tapping the exc key while the computer boots. If your licky you may be able to set yourself as administrator and give yourself admin rights. With admin rights you can do anything.

You can reset bios password with pull cmos cell from motherboard. For that open back cover of laptop then you can see motherboard chip set. Pull cmos cell from motherboard for 10 minutes then all settings goes to defaults. Then it will not ask for password. Let me know if you need further assistance.Thanks for using FixYa.

Hey,
you can reset the bios with a boot cd called ultimatebootcd which is free.
http://www.ultimatebootcd.com/download.html
It contains a program called !bios or iBios from which you can run a reset / attack on the bios and it removes the password.
Or you can run the wipeCmos utility
they are all under the bios selection.
so you download the cd image from the above linked page (scroll down to find the links) burn it to a cd start the machine from the cd select bios run !bios perform the standard attack. restart the machine and the password should be gone.

Done it on my own laptop some time ago.

    Also there are bios password recovery utilities on the !bios program that might be able to read the password and show it to you.

You can remove that password by removing all power sources to the laptop. Disconnect from AC power, remove the laptop battery, and then remove the CMOS battery located under the hinge cover. You can find detailed instructions with pictures here
http://support.dell.com/support/edocs/systems/latd620/en/SM/coincell.htm#wp1111212
Remove the CMOS battery and hold for a minute and put the battery back in. All BIOS settings including the password will be reset to factory defaults.

Hello
In order to reset the bios password you must remove the button/coin cell battery called the CMOS memory backup battery. Below you will find a link to the service manual section for your model D620 that explains with pictures how to remove/replace the battery, in your case remove the battery for 5 minutes, the Bios password will then be reset.

    After submitting my solution for the Bios password reset I see you have already tried removing the battery (additional comments by you are only see after I submit my solution), so here is what is needed to clear the password, go to the Dell support link below, it provides the information on how to get the password reset in your model D620 Laptop, there is no "master password"

I'm assuming you're referring to the Administrative password for this model.

You will have to contact Dell by phone and give evidence that you are the owner of the notebook on record with them. Once that has been done, they will give you a Master Password that you can use. There may be a charge for this assistance.
