P14s 3rd Gen CFG lock help needed
Posted: Tue Jun 20, 2023 12:45 pm
Hello folks,
I am trying to find the CFG lock entry in the BIOS firmware but I cannot seem to be able to find it in UEFITool.
As BIOS image I am using the Bios Update BootCD Lenovo provides. The other bios update option comes in the form of an .exe application. Is the Bios Update BootCD what I want in this case?
Could anyone provide the PATH to the CFG lock entry in UEFITool?
I suspect CFG Lock must be enabled since I am unable to undervolt the laptop, and cannot write to E2, see output below.
Factory resetting the BIOS and disabling Secure Boot did not help.
Any help will be much appreciated. Thanks
