I have a Lenovo H415 with an A6-3600 APU.
I had to do a fresh install of Win 7 after a crash
I have downloaded the latest catalyst drivers from AMD and installed them. I then went to Lenovo site to look for more drivers to resolve the only conflict I have left. SM BUS controller.
this driver support site at lenovo Drivers and software - Lenovo H415 Desktop
revealed 3 chipsets for AMD.
I eliminated the first because it said USB 3.0 which I don't have.
I downloaded the other two and the 1.22 MB download is corrupted which left me with this one AMD Chipset Driver for Microsoft Windows 7 (32-bit, 64-bit) - IdeaCentre K315,Lenovo H415
AMD Chipset Driver
That did not resolve my conflict so I went to catalyst site again and downloaded AMD Driver autodetect and it said I have the latest driver installed.
Lenovo support is worthless and they cant help. They never sent a restore disk with drivers
