I'm not the one with the laptop mate, you'll have to visit your laptop manufacturer's website and also read the AMD pages for W8 drivers etc ..
If you read the AMD Catalyst Mobility release notes, you'll see what laptops aren't supported .. those with switchable Intel Graphics being one such set of machines ..
You need to go to Lenovo's tech support and ask them about it all .. it's their machine, they should be providing drivers and driver support for it .. and they'll be able to tell you if that machine is 100% W8 compatible too etc ..
