Microsoft maintains a repository of verified drivers for older hardware: Device Man shows dead hardware: ACPI/IBM0068. What is it?
You might consider blacklisting the old ibm_acpi (deprecated) module. However, modern kernels no longer contain this module separately. Do not attempt this.
The solution was a patch submitted to the Linux kernel. In 2011, the code was updated to include LEN0068 as a valid identifier, ensuring automatic loading on newer Lenovo ThinkPads. This pattern repeated itself, leading to the addition of an even newer identifier, LEN0268 , to maintain compatibility with the latest laptop models.
