WMI is two things:
1. proprietary API to some data already available in ACPI
2. standard for organizing system information not yet listed in the ACPI

What you can do with it is totally dependent on the system. Sometimes it
offers a lot of info, sometimes not. With laptops, I think most
manufacturers ignored WMI and ACPI and wrote their own hotkey drivers.
