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.
Model: Dell Latitude 5400
Reg typr No: P98G001
Board: EDC41LA-G891P
REV: 1.0 (A00)
SERVICE TAG: 7404yy2 or 74o4yy2 (not sure )
Thanks

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, π π π ... -

So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the... -
Hello everyone,
I'm working on a Dell Latitude 5490 with a LA-F401P motherboard that has a very peculiar issue, and I would appreciate your insights.
Initial Problem:
The laptop was completely dead, no signs of life, no power LED.
Action Taken:
I flashed the main BIOS chip with a clean dump. This brought the machine back to life, but with a strange limitation.
Current Situation & The Main Issue:
The laptop now works perfectly when powered through the USB-C port. It charges the battery, powers on, boots into the OS, and functions 100% correctly....
