Yep. You could also try to load the wmi driver with: debug_event=1 e.g. adding this line: options wmi debug_event=1 in /etc/modprobe.d/99-local.conf or /etc/modprobe.conf.local (the first is the new the latter the older interface, depends on your userspace versions) Then hit the button and check syslog. It might also be served by a Windows spec called "hot start" for which I sent a driver which would still need some polishing some weeks ago. The device for these is: PNP0C32 Please add me to CC if you open bug at bugzilla.kernel.org. I won't have time to code, but I can help a bit.
