Hello.

I'm trying to fix a AIO HP ProOne G4 440:

ProOne G4 AIO MB Rev. B
348.0B723.0021
17564-2

As the first user comment in this post said, I also have power source led on board but have none reaction from power button when pressed. Even the dissipation fan doesn't move. The screen continues black, nothing happens.
Any ideas of what can I do?

Thank you in advance for any help you can give me.

From the HP Sure Start screen to the firmware recovery Management Engine it freezes at 50% then does an infinite loop.
I think the EC needs cleaning
I attach the dump of the 2 bios chips and photos of the screens

sir plz Repair bios
The screen does not open until after disconnecting the charger from the power source several times, and then it opens completely normally.

The device worked, but after it was turned on, it performed an update firmware, and then the problem came back again.

Attached are the original BIOS files.
