Tried this one, but same behavior unfortunately.

Same with this one. I have also tried replacing the ME region in the original dump as explained at https://winraid.level1techs.com/t/gu...lization/31277.
The processor is not getting warm and the coil near it has no voltage. The RAM voltage is OK. Battery doesn't appear to be charging.
Any ideas?Comment

Thank you.
Unfortunately I see no changes, but I have extra information: when I connect the battery and turn on the computer, after a while the LED on the front shows the following sequence: 2 amber, 1 white
According to Dell's manual this indicates CPU failure... can we exclude a BIOS issue or do you want to provide another binary I can test?Comment

Thank you, your BIOS is working perfectly (and probably the other ones I flashed too).
The issue was indeed the CPU, which was actually being supplied with ~1V but appeared to be dead. I solved it with a proper reflow.
I hope this is helpful for anyone in the same situation.
And, for reference, here are some thermal images before the fix:

Read the bios guides password topic, you might find a way to unlock it yourself, depending on what the suffix is ->

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, 😅😅😅... -
