I know that lenovo doesn't provide windows 7 support for this laptop. I have tried to install as many touchpad drivers as I found: Elantech, synaptics drivers from other models, even win10 Touchpad Driver for this laptop. I have found with linux live-usb that there is some elantech touchpad on my laptop: The F6 button with the option to enable or disable touchpad works too - it shows pictures with touchpad and crossed touchpad when it had pressed.
All Functional buttons work properly, even brightness control. All device in device manager installed correctly. I have modified intel hd graphics driver configuration file for installing too.
I have copied all downloaded drivers to laptop's hdd with linux based live-usb and finally was able to install them. After that, I found all vendor and device from device manager and downloaded all drivers. It wasn't easy because USB3.0 has no drivers at official windows 7 installer, so I added them to it.
A few days ago I have bought lenovo ideapad 330s-15ikb with Intel Pentium 4415U and started to install official microsoft windows 7 enterprise with valid license key.
