help me to modify the Bios after CPU Swap form i7 1365U to i7 1355U

[MAREBELE]

The EC on this is npcx998 The board doesn't turn on at the moment even after clean the me. I doesn't know how to clean the nvram, maybe that would help.

The replacment cpu is prom a known good motherboard so I can cross the possibilities off a bad donor

If possible please help me.

Thanks in advance

From what make/model of motherboard did it come from.

[MAREBELE]

its from dell vostro 3530 / LA-M367P,

additional info:
The board is charging

The PCH has intel boot guard. You could only use that SOC as a donor for another dell

[MAREBELE]

i have a few other board but its all dell board,i also have HP and Lenovo but it i7 1360P not U,

does all dell PCH is boot guarded?,

and also is it not possible to dissable the boot guard thru bios modification?

[MAREBELE]

i got my hand on HP Elitebook G10 and swap The CPU from there after clean the me the board is turn on. Thanks for the support

Hello everyone,

While desoldering the BIOS chip on motherboard [HP Dragonfly G4 , 5CG4425PBB], I might have accidentally removed a nearby SMD component.

I’m attaching close-up photos of the area.
Could anyone identify what part should be here (resistor, capacitor, diode, etc.) and its value?
Also, will the board boot without it, or is it critical?

Thank you in advance!

I have an HP Dragonfly 13.5" G4 (SN 5CG4425PBB) which does not start.
Symptoms:
- When I press the power button, the screen stays black.
- The power LED blinks 7 times in a repeating cycle.
- No reaction on external display.
- Tried key combos (Win+B, Esc+F2) for BIOS recovery – no success.
- Full power reset (battery disconnected, power button 30 sec) – no effect.

What I suspect:
Looks like a corrupted BIOS.


Questions:
1. Does 7 blinks on Dragonfly G4 really mean BIOS failure, or could it be something else?
2. Does anyone have a clean BIOS dump for this model / same motherboard?

Any help or a working dump would be greatly appreciated.
