the x5650 is compatible with XP, Vista and Vista 64

Here is the HP Support page to download the Vista software.

D2360 Vista Software

Uninstall any software you have already installed and reboot before downloading and installing the Vista software and driver.

As per my knowledge, there is no version of Vista called Vista Professional like in Windows XP.
Make sure what is the version to which you want to upgrade to from Vista Home Premium to Vista Business or Vista Ultimate.
The available versions of Vista Operating Systems along with the features supported from the Link below :
http://www.microsoft.com/windows/windows-vista/compare-editions/default.aspx

However, if you want to Upgrade the current version of Vista to a higher version like Vista Business or Vista Ultimate, you need to purchase Vista Anytime Upgrade kit from any retail store or directly from Microsoft.
You can find the required information related to Anytime Upgrade Kit from the link below :
http://www.microsoft.com/windows/windows-vista/get/anytime-upgrade-overview.aspx

However, make sure that you had created the Recovery Disks for your notebook using which you will be able to reinstall the preinstalled Operating Sytem along with all the Preinstalled Applications and Drivers after which you need to use the Vista Upgrade Kit to upgrade to higher version of Vista.
However, if you are currently having a 32 Bit Vista preinstalled in the Notebook, it is not possible to upgrade to a 64 Bit Vista since you can upgrade only a 32 Bit of Operating System to a higher version of 32 Bit Operating System and a 64 Bit Operating System to a higher version of 64 Bit Operating System.
Hope this helps....
