Re: Dell Latitude 7400 Bios Password
Only flash this file. In the first boot , you have to go into bios setting for disable all the security options , avoid activate " Computrace " and " Absolute " features.Attached FilesLast edited by hoaca388; 07-18-2022, 07:43 AM.↵

Re: Dell Latitude 7400 Bios Password
There is another chipset on back of the board marked UC5 64Mb, that one has to be modified.----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Re: Dell Latitude 7400 Bios Password
thanks to everyone who has been a great help with my limited skill of flashing bios chips.
I have purchased a dell 7400 from auction with the dreaded *******-8FC8 prefix. It not only has a bios password but it has been locked with Absolute. I have experience with a 1341a mini and a clip as i dont have very good soldering skills. before I spend my time disassembling the latop, will a chip clip fit on this chip? can the absolute also be removed?Comment

by jhanraHi 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, 😅😅😅...-

by anlsmithI 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...

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.
I reinstall...-
