A reliable method can be found here:
http://www.cgsecurity.org/
look for Password recovery.

Try the backdoor password Dell

Christophe Grenier has written a program that will calculate the master BIOS password for Dell Latitudes from the Service Tag number. That program is available at http://www.users.globalnet.co.uk/~sk...s/latitude.exe.

if you call dell they will help you !! They will generate a working key that will disable the bios password.

Call again

I don 't believe you can run a DOS based program with XP. You will need an older OS such as 98 (the one I used to run the program). Unfortunately, the one I downloaded just askes for the service tag. As soon as I enter the first key, I get the message that the program is shutting down. Anyone have a working copy of this program???
Thanks.

Go into a command-session (or DOS-box) in any OS you like.
Go to the directory with the LATITUDE.EXE program in it (size is only 5,467).
Type in latitude 12345 and hit enter.You have to substitute 12345 with your 5-character service tag number. The program then gives you the password.
Simple (if you know how to).

Attached is a working version in a zip-file

Edited by Per: Note that some antivirus programs might indentify this file is a "hacktool" that is perfectly ok, the file indeed is a "hacktool" but it does not do anything "bad" to your computer.
That is it only does what has been explained in this thread and that classifies it as a hacktool...

Assuming you have a floppy drive. Try running the latitue.exe off of a DOS boot disk. That way you bypass all the XP/NT compatibility issues.

If you don't have a boot disk handy, DOS boot disk images can be found for free at a website called bootdisk-dot-com. Make sure you copy the latitude.exe on to the boot disk.

Thanks, I got it to work, however, the password is incorrect.
Any other options?

If you do a google search on "latitude.exe" there is a couple of forums that could help you.

I snagged this blurb from someone on the windrivers forum who was having a similar problem to yours

Hi, I just had the same problem with my Dell CPI. I used that program in latitude.zip and it worked like a champ! Now you say your service tag is CD10V, that is only part of it. When your PC boots up and asks for the Password you should see CD10VV-**-xx or something like that. I thought the ** was some hidden letters/numbers but I typed it exactly how it was displayed and the Password given worked. My Laptop had done this before but then eventually let me in. But this time since I used the Recovery password, I found out that the letter O is not working with my keyboard. O is in my password. A couple other keys were not working also. So I got lucky the backdoor password didnt use any of those letters. I guess I would have plugged in an external keyboard.

Have you tried removing the CMOS battery for a day or so; let the charge dissipate completely. This used to work on older bioses!

I think that works on ALL of them

Since the CMOS stores all the settings, removing/replacing the battery will reset the BIOS password.

Unfortunately, NO.

What would be the point of a security password that could be so easily bypassed..?


Laptop computers use far more stringent methods of securing themselves than old desktops used to.


Removing the CMOS battery will NOT remove the passwords on a typical laptop. The passwords are stored in a NVRAM area, usually in the same chip that the BIOS is stored in. Simply removing power to this chip will NOT erase it.

Oh, I didnt kno he was using a laptop

I am not all that familiar with Dell systems

But yes, laptops use enhanced security and it is a lot tougher to bypass

Where can one get another one of these chips? I can easily desolder and resolder a new one.

: all bios passwords can be removed easily,

: 1-create a dos system disk,
: 2- copy "debug" (this is a dos command found in windows\command directory) onto the system disk you created,
: 3- boot the machine with this disk,
: 4- at dos prompt type: debug then enter, you will see a blinking dash
: 5- type: o 70 2e then enter, (also seen: o 70 18)
: 6- type: o 71 ff then enter,
: 7- type: q then enter,
: 8- remove the floppy and reboot! Power the system off and on by unplugging and re-plugging the system into the power outlet

: send me a thanks mail email removed

Ihave already made an attempt to reset it by doing the proceedure in the post above. No luck, my quest now is to hunt for one of these chips and replace it.
