Re: Links for Graphics drivers
If you want a link to the graphics driver, it's over at support.AMD.com. Fill in the drop down menus with your hardware and it will direct you to the drivers. You will need to install it with a few commands. It's not very hard, and AMD explains how to do it rather clearly. I think it's like 2-3 commands in the terminal, which you can always just C&P.
The other drivers, I couldn't tell you. That might be a trip over to Lenovo to see what they recommend.
