Hi everyone,
I have a Dell Latitude 5430 (Service Tag: 4HK5GK3) that originally had a BIOS password.
There are two BIOS chips on the motherboard. I identified the main chip and successfully read and saved its contents using a CH341A programmer.
Here's what I did:- I read and backed up the original BIOS from the main IC.
- I then erased the chip and flashed a clean BIOS file (no password) from the internet.
- After installing the chip back into the board, the laptop no longer powers on — only a brief power light when pressing the power button, then it shuts off immediately.
- I tried to recover by reprogramming the original BIOS dump back to the chip — but the laptop is still completely dead. Same behavior: power light flashes briefly and turns off.
- Determine what went wrong?
- Suggest how to recover this board?
- Is it necessary to flash the second BIOS IC as well?
Thanks in advance!Comment

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...
