> Can you write which WMI call needs to be called? Technically, one needs to call method DoBFn (method ID = 1) using GUID A80593CE-A997-11DA-B012-B622A1EF5492. Though if you look at the ACPI method this GUID maps to (WMBA), you'll notice that the first two arguments passed to it (instance number and method ID) are simply ignored and the only one that matters is the buffer passed (third argument). > Last time when I looked into dell-led.c code it called some WMI > functions which are just re-implementation of SMI based SMBIOS > functions.
