I also have this problem with the drivers. The drivers provided on Lenovo's support page can't be used. I installed newer drivers directly from AMD, which seemed to work. But now, instead I get alot of BSOD-restarts, related to drivers issues. Anyone know how to permantently fix this? I am hoping Lenovo will provide newer drivers for the discrete AMD graphics card, the old ones are from November 2015, which is right at the beginning of sales for this laptop. I noticed the ThinkPad E570 model (which is now available) don't have Windows 7 drivers at all, nor Windows 8.1 drivers. I can only assume that means we wouldn't be able to run Windows 7 with full funktionality on that new model, so would really like to get this (the E560) to work properly.
