Wireless LED problem in HP laptop: always white (even with Airplane mode on)

I had a problem this days with my HP ProBook 4540s laptop. On the top of my keyboard I have are 2 extra button, one for internet and one for wireless communications (WiFi network, Bluetooth). Pressing the wireless button, my computer will switch on/off the Airplane mode. When The Airplane mode is active (with no wireless communication enabled) the LED is orange. When the Airplane mode is off (WiFi communication is enabled) then the LED indicator is white. Everything was fine until I updated my Windows 8 to Windows 8.1.

In Windows 8.1 the button is still working fine (enable/disable Airplane mode function) but the LED indication never turns to orange, is blocked to white no matter the status of my WiFi connections.

After searching a lot of solutions I found that the problem is caused by the Bluetooth driver and a simple update provided by HP will solve the problem. So, if you have the same problem as I did, just download and install this driver update:

Have fun! All the best!
