Problem with keyboard in windows 7

Hi, I have bought Lenova G460 Laptop with Windows 7 as OS.

When i connect to my office desktop via remote desktop or when i login to other OS via Oracle Virtuabl box. The keystorkes which I type in characters are translated to numeric keys. But if combine (Windows Key) with the characters, the characters are typed correctly

I am not able to get any support from Lenvoa Support team. They say its the problem with OS.

I would appreciate if I can get any help.
