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.

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:

• 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".)
