Well, I don't know if any of this might help as I know nothing about these things. I assume you can't just ask the shop where you bought your new laptop from.
Possibilities. Usual caveat about risk of changing things, as I'd be no help if you needed to do a complete re-install!
If it is a missing or outdated driver, you might find one of the free driver download sites might detect it, such as

If it's a synchronisation problem where it's not recognising the corrrect com port, that a diffrent thing from any driver issue it seems.
If you have a bluetooth icon, could try: start > settings > system > bluetooth settings > Activesync over blutooth (START)
Have a look on here to see if any of it looks familiar. Or ask your own question there.

Microsoft Windows Device Centre might help.
Cable & Wireless "Support" menu option has a "contact us" email section you could try in any case.
Best of luck.
