WIFI is disabled by hard switch hp 430

Question

I searched and tried many things to resolve this issue but nothing helped me. Please find the methods below that I tried.

OS: ubuntu 14.04 Laptop: HP 430 (64 bit)

1. Checked the radio transmitter kernel subsystem rfkill list all

   Output:

   0: hci0: Bluetooth
       Soft blocked: no
       Hard blocked: no
   1: hp-wifi: Wireless LAN
       Soft blocked: yes
       Hard blocked: yes
   2: hp-bluetooth: Bluetooth
       Soft blocked: yes
       Hard blocked: yes
   3: phy0: Wireless LAN
       Soft blocked: no
       Hard blocked: yes
   

   Based on the above output, it is a hardware lock. So, Checked/Changed the BIOS configuration settings for hot keys or fn+F1 ..F12

   By referring this link. But no help.

2. I suspected drivers. So, I cross checked the drivers and followed the procedure which is mentioned in this link - Sadly no help

3. I decided to disable the hot keys function itself and I followed this thread for that. Again no help.

If you are not able to give solution for the hard lock issue. I am fine with enabling the wifi in startup also

Edited: Added more information about system drivers, etc
