I flashed these files. I updated the BIOS to the latest version. The laptop displays the error "hp endpoint security controller problem" after each startup.

Try the endpoint patcher with the main bios. Post 5 https://www.badcaps.net/forum/troubl...security-error

I did as instructed. The error is gone, I entered all the MPM data and configured the TPM. The laptop complains about the lack of a MAC address. I scan QR-code on Wi-Fi module. All work. Thanks

Hi All
I've been repairing this machine and bought a donor board for spares, unfortunately it turns out the original MB has a shorted cpu so is toast.
So now I'm trying to repair the donor, this has all the required voltages, no shorts or physical damage but won't boot, it flashes 5 power lights and the caps lock once, so generic hardware failure.
I've had something similar on another machine and that was bad joints on the EC chip, I've reflowed the EC chip on this board and it's no different.
My working theory is the EC chip bios is corrupted or the EC chip has failed and is preventing the board from starting up, would someone be able to take a look at these files and check for corruption and clean/remove passwords if possible, If this fixes it I'd need MPN enabling so I can change the details to match the original board.
My other question is could I transplant the bios chips from the original board?

Any help/advise would be greatly appreciated.
