Hi. I think I have the same problem as mhd bero.
A client came to me with a messed-up bios uploaded from the forum with an incorrect serial number. When I restore the bios from the second memory chip, the effect is the same.
Everything seems to work fine except the wrony S/N, message "Machine Is Not In Committed State" and the lack of MS license.
Can you help?

Everything is fine, although at the beginning after booting from the pendrive to install the system, the keyboard and trackpad stopped working.
Additionally, after installing the system, apart from the keyboard and trackpad not working, it did not show information and the battery icon.
After updating the firmware/UEFI again from the system level, everything returned to normal.

Respect and Regard, Thank you very much for help.

How can I repay?...

Hello, I have been servicing telephones for 8 years, and for almost three decades I have been repairing various types of electrical and electronic equipment. However, I am not a highly specialized electronics engineer, but a home-grown self-taught person. Best regards to everyone,
