Thanks so much for the help! This is my first time looking at an ACPI dump so I never would have found this. > Maybe you can write a wmi driver which handles both WMI objects, so that you can find out what the values > returned by GetUsageMode mean. With a bit of luck, you can use this to implement tablet mode toggle detection. I will look into this, this does look more like the proper way to do it so it can be put in the driver for everyone. I suppose that missing Notify device is just unrelated then? Does setting the memory mapped variable just automatically update these WMI devices? I was worried that the failed notification would make the WMI devices not work, just guessing based on the WM00 name. If you have any pointers on where to look to see the kernel functions involved in WMI that would be appreciated. > BTW, what is the name of your notebook model? It is advertised as Lenovo Yoga 7i and the model number is Yoga 7 14IAL7
