                        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.

                          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
