Mobile Broadband Not working.

Hp ProBook 6440b
Microsoft Windows 7 (64-bit)

Hi Everyone ! I have Hp-ProBook 6440b, with windows 7 (64 Bit) installed. The issue is that mobile broadband driver is not working properly. I've installed latest drivers from hp, did almost everything, But it still isn't working. When i open Hp Connection Manager, on Mobile Broadband (WWAN) tab, it says "Disabled by device manager". And when i go to device manager, > Ports (COM & LPT) the driver "Hp un2420 HS-USB QDLoader (COM 4), it says the device is working properly. And when i go to "Network Adaptors there is no driver installed for my Mobile Broadband. 
Please help!!! I'm attaching images of HP Connection manager and deiver manager.
