As for the synaptics menu, I don't have it.
In that case you can't do anything about it, unfortunately. The Lenovo forum is full of posts like this. Because on this model in the current driver, Lenovo just omitted the usual Synaptics menu and you can't set the values unless you go to the Windows registry and find the specific values to adjust your wanted setting, but then you'd also need to find out what subvalue you'd need to set to what and these values and their subvalues aren't explained anywhere as they are usually changed via software. Which means that there isn't a viable way to change them. What I'd try in your case is go to the Windows Settings menu->Devices->Touchpad and see if that even offers any sort of settings. On my Lenovo Yoga 530 it only shows settings there due to the fact that it has Microsoft Precision drivers and not just Synaptics or another manufacturer.

Well, I did what you said, and it solved my 1st problem. Lenovo Utility solved it.
Well, that's good to know. Had the same issue with my Yoga 530 and this solved it.

The 3rd seems to be that due to some pressure on it's back I may have a dead pixel.
When it's just in isolated parts of the screen, most likely yes.
