Hi, I have similar problem to that, ACPI\VPC2004 already solved by your solution but I can't install AMD drivers from lenovo website. Error during catalyst manager installaton. In device manager I have one missing driver - video controller.
Intel drivers works fine.

After installing all drivers from the lenovo website, i still have the ACPI/VPC2004 as unknown device.
