I have switchable graphics HD4225 & HD5430 discrete on my HP Pavilion dm3-2015er laptop.

I use the latest driver for old Radeons (up to HD4000) - 13.1. But I cannot find the driver to be able to use my discrete graphics HD5430. Could you help me with this issue?

I use Windows 8 starting from Nov 1st, 2013. I am waiting for the compatible driver from AMD 10 months already.

HP will not support "old" laptops.I hope that AMD cares about its customers instead of HP.

My HD4225 works well now. I use AMD driver. The brightness level is adjustable. But I wish to use my discrete card also.

I have AMD PowerExpress installed for my switchable graphics. But when I click on High performance GPU button nothing is happens.

I think that I am on the right way to solve the issue.

If you will help me, it will help thousands of people with the same issue.

HD4225&HD5430

As I see it, you ""updated"" your laptop to Windows 8 from the OS it was designed for. The 4xxx drivers are not fully compatible with Win 8 as noted in this AMD article. AMD also states that any laptop using a OS other than the one it was designed for will have issues with AMD generic drivers. So if you go back to the designed OS and use the last driver offered by HP for 'switchable' graphics you will be ok. As the article says, switchable graphics have drivers the are designed to work only with your model laptop and can't use 'generic' drivers without losing some functionality....such as the 'switchable' feature. You might check the HP laptop forum for similar posts, or ask the HP laptop community for guidance. Possibly there is a setting in the bios to disable the intergrated graphics chip and force the discrete graphics to primary.
