Admins always past this link like it was easy to do. I have an idepad 3i i5 too and I am having problems to find one EFI too. So as admin shows, I just need to download an EFI to notebook cometlake and it will work. I don't think so.
Alexandre, a EFi do S145 ficou perfeita no 3i? O trackpad pode ser resolvido, se for só isso
