the problem returns when doing Windows updates, the solution I found was... go to the EFI partition, originally 100mb, delete the HP folder and respective files, and reduce the size of the EFI partition to around 40mb... the machine still tries to update the firmware but stays at the initial warning and reboots and continues to start Windows....

You were right, hardware problem, on the board, the primary power supply +12vsus was missing, caused by a failure of the BAT54SDW component in position PD8701, resolved by replacing it. Thank you...

machine is working with files from post #17, thank you.

with endpoint error and manufacturing mode but working for testing......

hello forum.

Machine entered the workshop with symptoms of not turning on, with no consumption on the energy meter, after inspection I did not find any signs of failures at the hardware level so I reprogrammed the two chips u366 and u367, the machine gave a sign of life, it started to give an error from "HP Endpoint Security..." but it was functional, after doing the last update of the bios through the HP website, it worked well until part 2 where error 7 appeared and stopped turning on, I tried the key combination "WIN + B" but without results ... if possible...

thanks but not detect nvme...
