Windows 7: Access 2010 under Windows 7 on HP Probook

I have successfully run an Access 2007 application on a Dell Notebook (Vista and Office 2007), several desktops and on a Dell Netbook (Windows7 and Office 2010), but it runs extemely slowly on a new HP Probook (4gb mem), to the extent that it is unusable.
A very cut-down version of the database built from scratch with just one table and one form also runs very slowly.

Has anyone else had similar experiences and are there any ideas for a fix.

Thanks,

What are the specs of the Netbook? I'd expect it to run slow, but it should be usable.

Thanks for the response Deacon, I also expected the Netbook to perform as it does, but the spec of the Netbook isn't relevant to the issue as it is a pup in comparison to the HP Probook that has the issue. I just entered its details to show that a Netbook works ok, yet the Probook with the same software platform doesn't.
The probook has 4gb main mem, dual proc (2.4ghz) and a Windows rating of 4.5, so should "eat" the application.

More system level checks shows that the HP ProBook has better performance specs that the other PCs on which the Access application run successfully. So it could either be a HP system implementation issue or a problem with the Access 2010 load.
The ProBook is a brand new PC by the way.
