Hello! Just been poking around my own HP device. How do I get the same information you did about my own device? So far I know 3 important EC addresses
0x11 (Monitors fan speed when controlled by EC. When manual fan control is enabled, this register is not used.) 0x15 (Enable manual fan control. Accepts 0 as automatic (default) any other number denotes manual control. This is RESET after waking from sleep or rebooting the computer.) 0x17 (Manual Fan control WRITE and READ register. Accepts a value of 0 to 55. UNUSED if fan control is set to automatic) Some values between 0 and 55 are reserved for automatic control via the EC. Preferably we could skip these. The values are 26,31,38,43,47,53
The superIO chip is a ENE KB9022Q-D (Had to teardown the laptop to find that one...)
Check your DSDT and those FieldUnits above should be at the same offset in EC.
I have no idea how to read a DSDT but here's the section relating to fan control I think.

FWPM doesn't appear in the sample I found. However, FRPM and FNTV do exist and are available in WMI functions. Related function is not hard to understand:

My Fan Control definitions are actually found in a SSDT which is fine because MACiasl can still read it. This seems to be close to what you found.

Note: No FWPM here... Or anywhere else except the DSDT... What is going on?
Just check if somewhere else use FWPM. The driver should be able to read and write other ones through the WMI interface.
