Comment # 25 on bug 956403 from Silviu Marin-Caea

### Without hp_wmi, only with "wmi", WiFi and hardware button work.
silviulaptop:~ # lsmod | grep wmi
wmi                    16384  0
silviulaptop:~ # rfkill list all
0: phy0: Wireless LAN
        Soft blocked: no

2: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

### Load hp_wmi
silviulaptop:~ # modprobe hp_wmi
### The WiFi LED goes out, button does not do anything

silviulaptop:~ # rfkill list all

### Unload hp_wmi

### WiFi LED stays out, button does not do anything

### At this point, the only way to get WiFi back is by rebooting, going to BIOS
and "Loading Defaults"
