Ati mobility hd 5000 series

Lucky for you - the ATI download sites has ATI Mobility 5000 Series drivers.

AMD Radeon Graphics for Notebooks
--> Use Find A Driver

That won't help. AMD doesn't provide drivers for notebooks to consumers, they provide reference drivers to the OEM who made the notebook. They only provide a few tools and other junk to consumers.

Notebook drivers can be obtained from the manufacturer of your laptop. It is possible to install tweaked drivers from third party sources but I do not recommend this as it will often break features specific to your laptop

What laptop do you have?

Unfortunately pinhedd is correct with this nowadays. I had a dell laptop with a mobility 4670 and i could install ATI's reference drivers on there no problem but once i upgraded to a HP with a 6470 i couldn't install ATI drivers anymore unless they were HP's own modified drivers because ATI comes up with a no recognizable card failure if you try ATI's own driver instead of your manufacturers.
