Installing LL 3.4 on Lenovo Yoga 710, i7/7th gen

[Valtam]

Just a quick question. When I change someone over to Linux, I take a LL loaded USB drive into the retail store and ask to load up LL (with Secure Boot and UEFI disabled of course). Only when all of the hardware proves to work and there are no major issues, does the person commit to a purchase. Have you tried this approach? It is of course, in the interests of the store in question to secure a sale, so they will nearly always cooperate.
