Bios Request. DELL Latitude 7440

[peste]

Hello,

I have a Dell Latitude 7440 13th generation that I purchased at an auction, but it has a BIOS password, and I cannot change any settings in the BIOS. I would like to rewrite the BIOS data, but I can't find it anywhere. Can anyone help me?

post the S/N, post the original content of the bios chip, the motherboard model, etc.

Hello,
I had an old Latitude 7440 (2014), but the admin password is blocked.
I've try BIOS-PW.org, but it doesn't help me... more I'm now blocked on the Dell Security Manager page at each restart (picture attached).
Is there anyone to help me ?
Thanks

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.

Hey everyone.

A couple of weeks ago I bought a laptop from a second hand shop in the UK called "Cash Generator". A week later I was locked out by what I believe is CompuTrace. I returned the laptop, exchanged it for another similar spec laptop and they sold me the original for £100 as "parts". Now I need a dump of a BIOS so I can get this one back up and running. I've dumped the W25Q256 and W16R128 for backup, but honestly I have no clue what to modify in order to clean it...

The ICs are next to each other on the board. I'm not sure which one is needed...
I also did a checkmend on the laptop. It hasn't been reported stolen, so it's legitimately owned and can be modified. I want to get it running for my son

Can anyone help?

Hi, nice to meet you everyone. Recently i bought a batch of refurbish latitude from ebay. Although there is no issue with installing/reinstalling windows they are all bios locked. Made a case on ebay and seems they dont grasp the concept of a locked bios so my only option would be either to unlock them or to return to seller with my expense since they understand that "its a me issue". Thats quite the cost since it was overseas and quite heavy package. Id like to try to unlock one and if its possible ill go through the rest.


The model is dell latitude 7440.
Tag 3NP8BY3-8FC8
The bios chip says winbond 25r128jvsn 2315

I was not able to find the specific chip on the list in Asprogrammer but when pressed detect it went as W25R256JV ?? The cap was read as 256 but i saved a copy of 128 just in case both included in the rar.
Not sure if this will work or i have to re-read again please let me know.

I dnt think it worked this time as well. all is FFFFF

I think i am reading EC chip not bios. Bios chip is soldered cant read easily with ch341 adapter. Have to read bios chip for bios password right? If that's the case probably i will go with return since i dont think i will be able to do unsoldering and soldering on them.

Thanks for looking into it.
