Good day all, I have a Latitude 5400 that doesn't power on at all, keyboard lights up and it turns off after 15-20 seconds or so. I'm thinking it could be a BIOS issue as I have already tried replacing all other parts.
Model: Dell Latitude 5400
SN: H59P3X2
Board: EDC41LA-G892P
REV: 1.0 (A00)
PWB: R0R0W
Has one 32MB flash chip, which I dumped with flashrom.
Thank you for your helpComment

Hi all,
I am new to this forum which I am finding very usefull, and as many other users I am looking into fixing Laptops which are protected by BIOS password.
Fixing Laptops is kind of a hobby for me in the spare time.
I was reading all 4 pages and was not able to ton identify information that I need. I am reading other thread ( Dell Latitude 5400 Bios password), but didnt reach beyond page3 as o now . I've read the " BIOS guides, methods, resources and tools" section as well.
I have few DELL 5400 which have administrator password and some of the BIOS sections are locked.
First issue I am facing is that I am not able to identify the CHIP I have to read cause on the motherboard there is a UC5 (25B64CYiG) and an UC6 (25B127DS1G) and UT6 (25Q80DVSIG)
I was trying to clip the UC6 (25B127DS1G) to CH341 but is not recognized.
Second, I am not sure CH341 is good enough to read the BIOS and post it here.

try these programs for CH341a, if it doesn't work, choose a similar chip from the database..

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, 😅😅😅... -
