HP EliteBook 8560p Networking :: Cannot Turn On WiFi - Button Is Orange

I have a problem with my wifi. The button is always appearing orange, and nothing happens when I press it: no errors, no messages, no reaction at all. Therefore I cannot use wifi connection.
 
The laptop is kinda new: I am using it for only 2 months.
 
1. Product Name and Number
HP EliteBook 8560pНР LQ589AW

 2. Operating System installed (if applicable) 
Windows 7 Professional 64 bit
 
 3. Error message (if any) 
No error messages

4. Any changes made to your system before the issue occurred

My windows crashed and I recovered it from the archive created a couple days prior to that. Archive included all hard drives data, so system was restored exactly as it was prior to the crash. I am still not sure if this caused the problem (or if the problem appeared after that): it happened a month ago, and I didn't have WiFi available back then, and only tried to turn it on a couple days ago.
 
Additional details:
In device manager wireless card is showing up as working normally. In adapter management wireless connection is turned on but says "no connection available". If I run the diagnostics, it asks me to turn on WIFI with a button on my laptop, which I cannot do. In mobility center it says "wireless connection is turned off". Turn on button is gray, and impossible to click on.
 
Things I already tried:
Reinstalled all HP drivers from the original CD;Removed WiFi card in windows device manager (deleted the device), restarted windows, installed new drivers for it, restarted again;Checked mobility center as was suggested in one of the threads found on this forum;Made a hard reset for HP laptop (removed battery, pressed on/off button for full minute).
