Question: We have some HP laptops here that comes equipped with a video card that identifies itself as "ATI Mobility Radeon HD 3650", like [this one](http://www.notebookcheck.net/ATI-Mobility-Radeon-HD-3650.8839.0.html).

However, which drivers do we choose? As far as we can tell, HD 3650 is desktop cards, or at least there are no drivers listed for that series with "Mobility" in their name.

If I pick the following on the [ATI Driver Download page](http://www.amd.com/se/Pages/AMDHomePage.aspx):

* Graphics
* Windows Vista 32-bit Edition
* Mobility Radeon

Then the dropdown for the card model contains X300, X600, X700, X800, X1300, X1400, X1600, X1800, 9600, 9700 and 9800 models, but no "HD" nor "36xx series".

However, if I change to just "Radeon" for the last selection there, I can find a "Radeon HD 3600 Series" model in the list.

Also, if I pick "Windows 7" as the operating system, I can find a "Mobility Radeon HD 3000 series" card, but no 3600.

So, which one to pick?

The main reason I ask is that they all seem to have some kind of problem installing, so neither seems to be the right one (they all crash with "Catalyst Install Manager has stopped working".)

Answer: 
In your case you would use the 3000 series drivers. For the record, when they say '3000 series', that means it pretty much covers all the models from 3000 to 3999. Not that they have a 3999 model but you get the point. It's basically like saying 3xxx series. 

When you run the install the software might say that your model is not found, but you can select the HAVE DISK option and manually pick from the list using the INF in your ATI driver folder. 

Some would say this is not recommended but in my experience, I haven't had any issues yet.
