I had dell 3542 with admin lock in bios, so downloaded latest bios from dell website (3442A16.bin), but could not able to match header or footer from backup file. Anyone can guide please, is it extractable or any other way to resolve the issue.

Dell E6430 19v line short
Dell E6430 19v line short,
(QAL80 LA-7781P)
19v rail, output side was showing a short (checked after removing CLR), a polar capacitor (PC1074-processor decoupling) in the core section was getting heat, when replaced that cap, the short gone, but when power on the machine, again that cap was heating (even had removed the processor already). so not understanding even no processor attached why this cap was getting shorted again and again
any guidance please.

soc getting hot, no display
The soc becomes a burning hot in exactly 2 seconds, is it normal or not?
There is no core, and the board is LA-C451P. (1.0v prime, 1.0v pch, vccsa, ram etc are generating).
Board taking about 500mA.
For testing, just inject 0.9V on core coil, the cpu normally heat but ampere showing 500-700mA.
Any clue.,.,regards -
