What does "never wakes up" mean? I thought I had the same problem but then I discovered that closing and opening the lid is the only way to get it to wake. Neither the power button (it turns it off) nor keypresses (they do nothing) work.
I think I tried everything, from buttons to lid to magic network packets. Once in S3 it's dead Jim, and there's nothing in the BIOS to change that behavior.
The irony is that I have a 4 years old XPS 13 where everything works like a charm, even under Linux. Talk about progress ...
