I've been having an issue with one of the drivers on my Lenovo G475 laptop (Windows 7).
I tried installing a windows driver update for the "AMD SMBus" but the installation failed with the error code 80070103.
When I go to system devices and double click on the AMD SMBus device and then on driver > driver details, it says, "no driver files are required or have been loaded for this device").
Apparently, the SMBus driver is a chipset driver but there are no chipset drivers available on the Lenovo support website for the G475 model.
Everything seems to be working normally and there are no yellow warning icons next to any of the devices in the device manager.
