Some people don't know this, but HP/Compaq do have updates for their laptops on their site. These updates include everything from BIOS updates to video card updates.
All you need to do is go to
support site and type in your model number. Be sure to type in the
exact model number of your laptop and not the model's series number.
ie: ZE4560 belongs to the ZE4500 series, but you would have to type in the first value to obtain drivers/updates for your specific laptop.
Remember, ATI does not officially support Mobility chipsets. They leave that to the vendor and thus sometimes features are not available when you use the Mobility Modder and install the Catalysts or Omegas on your laptop.
