Dell Latitude 5400 Bios password

[Lover1abd]

3.4. Dell

Dell laptops store the password in EC. However, some generators exist depending on the code suffix.
See: https://beta.bios-pw.org/ .If the website is offline try: https://web.archive.org/web/*/https://bios-pw.org/
Note: All passwords must be entered with a US QWERTY Keyboard,you can use a USB one.
Note: The 6FF1 suffix has a bug,use your service tag with the 1F5A or BF97 suffix instead,Example: 1234ABC-BF97 .
Note: The list of examples does not include some other suffix codes that do work,such as E7A8 .
Note: If the BF97 suffix does not work try it with the E7A8 suffix instead.
Note: There is no publicly available 8FC8 generator available at the moment.
The CTRL-ENTER-ENTER keystroke after the password only applied to laptops with a suffix (xxxxxxx-8FC8 for example), until Dell also required it in some laptops using System Disable 16-Hex algorithm, on which only the Password+ENTER was needed at first and then in some models you needed the CTRL-ENTER-ENTER to properly delete the system passwords, otherwise the password would remain SET upon the automatic system reboot if just doing Password+ENTER until the proper CTRL-ENTER-ENTER keystroke was performed in certain models.

Hello guys. I bought a Latitude 5400 from a site. I turn it on and it says "this computer is protected by a password authentication system".
Can you help me remove this password? Besides the model number, S/T, board model, which of the two flash chips should i remove and read to post here the content? There are 2 bios chips on the board. Thank you!

Hello colleagues. I've purchased 3 DELL Latitude 5400 laptops from Ebay and all they came with BIOS password locked. I though that I can install windows and use them but couldn't, as BIOS booting configuration even not allowing me to booth from USB flash drive. Could you please help me to remove password? What input information is required for that? I've service numbers for all laptops. Thanks.
