Re: Dell Latitude 7400 Bios Password
Please consider donation in support of the "Bios Requests" section of the forum.
At first boot enter the bios and input the Service Tag at the corresponding field, disable Absolute Computrace, save & restart. At the second boot, press Alt+F do exit MPM.
Good luck:----------------------------------------------------------------------------------------------------------------------------------------------------------

Re: Dell Latitude 7400 Bios Password
How did you read out this chip? I have no success with any programmer. I have CH341A, EZP2023+, RT809F and tried with neoprogrammer and as programmer too. Chip not recognized, if I try with W25Q256FV which is the same spec buffer will be empty or corrupted. Cannot read out proper data. Chip is encrypted or is there any workaround to read out?
I tried with special wson8 cable and wired up also.
Please help me!

Re: Dell Latitude 7400 Bios Password
Hello, what chip model is it? in dell motherboards the same model can come with a different chip... winbond, Xmc, Gigadevide etc... indicate the model of your chip.How did you read out this chip?

Re: Dell Latitude 7400 Bios Password
Hello,
I have been given a Dell 7400 i5 with a locked BIOS password.
I have dumped Mac BIOS's before but I am unsure which one is the eeprom on this motherboard.
Once dumped, what else would be needed please?
Serial number is DYN7733-8FC8
ThanksComment

Re: Dell Latitude 7400 Bios Password
I'm using a TL866ii Plus and using Xgpro v12.60, everything is making a connection, tested with a multimeter, triple checked all connections going to correct pads but the software can't autodetect the chip nor if I select the chip its detected, any suggestions on alternative software? I get "Pins Detected" but checked ID is showing 0x 00 00 00
Chip is a Winbond W25Q64JVIQ
Thanks

Re: Dell Latitude 7400 Bios Password
Sorry for another comment, does UC5 need to be removed from the board to be read? spotted there are holes in 4 traces that connect to the 2nd bios, is this maybe the reason software cant detect it? reading other section of bios also?
ThanksComment

Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅... -
I am trying to remove the BIOS password for a Dell Latitude 5430 motherboard LA-L591P. So far I think that I have located the BIOS chip but NeoProgrammer says that is detects 3 chips. I have attached the dump from each one. Are any of these the BIOS file? Service Tag: 1DMC1T3. If nyone knows the exact location of the bios chip as well I would greatly appreciate it... -
Hi
i have dell latitude E7270 with following symptoms:
- takes long time to restart.
- sometimes powers on and then off
- sometimes while working it just dies,
From googling online bios clean could possible resolve this?
i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)
As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.

Hello,
I am not experienced in electronics, but I really want to check if my idea is possible.
I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU).
BIOS/UEFI access on that MB/PC is blocked by password which I want to get it know - even if I need some bruteforcing or stupid manual activities.
There was no computrace activated.
I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.
1. I do not know how thebios...
