Hi:
I cannot confirm anything.
Your model is not supported by HP for Windows 7, so you have to find a business notebook (which you should have bought in the first place, if you need Windows 7), that has the same hardware as yours does.
Since the 450 G0 has the same hardware as your model, then in theory the drivers should work.
The only way you are going to get confirmation is to install the drivers you need, and see if they work.
