-

 After motherboard was replaced by qualified Lenovo technician, UMC was found a missing or incomplete of full MTM (83F10023ID) on current Legion 5 15AKP10, we had to recover the missing full MTM right here.

I will be using a BIOS Tool Right to Repair provided from Lenovo Support. It might take a while but simple with careful you're looking in a bottom label or visiting Lenovo Support to see your MTM.

Alert: The SN (Serial Number) / MTM (Machine Type Model) can be written only once and cannot be changed once written. Please carefully check your SN and MTM and verify the correct values before you input into the system.

This app has a company description for WinMBDWizard.exe is Hefei LCFC Information Technology Co., Ltd., a major manufacturing subsidiary of Lenovo Group Limited — one of Lenovo’s largest research, development, and production bases for laptops and other devices, located in Hefei, Anhui Province, China.

This confirmation verifies that the tool originates from Lenovo’s authorized supply chain and is not a third‑party or unauthorized executable.

Update: We cannot change the my MTM because was already exists but it was incomplete after replacing motherboard that previously caused power-gating to be fail in iGPU, causing black screen for several seconds and TDR was unable to recover.
