Hi Asit_47,
Welcome to the HP Forums!
I would like to take a moment and thank you for using the forum, it is a great place to find answers.
For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I am sorry, but to get your issue more exposure, I would suggest posting it in the commercial forums, since this is a commercial product. You can do this at Commercial Forum/Notebook - HP ProBook, EliteBook, Compaq, Slate/Tablet PC, Armada, LTE.
I hope this helps.
