Hi, I’m looking for the Lenovo SMBIOS update tool or BIOS Maintenance Utility (BMA) that can help me inject system identifiers (Serial, MTM, Model Name) into BIOS. System Details: Model: Lenovo IdeaPad Flex 5 14ITL05 BIOS Version: FXCN49WW Motherboard Manufacturer: LENOVO Issue: After a service repair, my BIOS shows "INVALID" for Serial Number and Product Number. As a result, touchpad, touchscreen, and other device-specific drivers don’t install or recognize hardware correctly. I’d really appreciate if anyone could provide the official Lenovo BMA/SMBIOS utility or Maintenance USB image, or guide me on how to rebuild these fields safely. Thanks for anyone welling to help me. If thread was not supposed to be posted ere please do inform me before taking any actions.
I did and it was not really the thing that let's me inject important values into the motherboard. So that is why I want Lenovo SMBIOS update tool or BIOS Maintenance Utility (BMA) that can help me inject system identifiers (Serial, MTM, Model Name) into BIOS.
I tried it it didn't work and also the main issue i cannot found any proper Lenovo SMBIOS update tool or BIOS Maintenance Utility or any proper Lenovo Golden Key U1 Tool. Majority of them online are botched versions that are not to be so ideally used in actual fixing of missing motherboard values.
The U1 Tool should have worked since its entire purpose is to inject the SN/MTM/PN/UUID on repaired motherboards. Are you sure you used it correctly?
The U1 tools that i have used tries for verifications and such and could verifiy properly and any of them that i have found are extremly botched in versions and are often quite unstable. that is the whole reason for me coming to this website Im trying to find a proper Lenovo SMBIOS update tool for my tiger lake laptop or any other tools that would help me fix this issue by injecting the missing values back into my BIOS. i have even tried IntelCSTools/CSME System and tried to use HxD to edit in the values but the datas are completely wiped out and I'm stuck unable to find a way to fix this issue that a technician didn't bother to do.
