Thank you very much

you have to upload your bios backup, not update from lenovo site. You can use bios from post 4 but you have to transfer your DMI (search for "LENV" in your bios backup)

Thank you, the DMI information has been restored, and the laptop is working fine. However, when I try to update from BIOS GXCN48WW to 50WW, the laptop powers on but does not POST. (Likely, I have a working backup BIOS that you created earlier.) Could you please make a BIOS based on 50WW, or should I continue using 48WW and skip the 50WW version?
