I suspect this is just the classic problem reported with Broadwell on 10.12.4 and later.
Try with 10.11.x or 10.12.3 if you can.

Is it possible to downgrade to 10.12.3 or only fresh install ?

10.12.3 sleep/wake working like a charm.
But bad news same problem on 10.13 :(
I'm trying to find diff in verbose boot between 10.12.3 and 10.13.
Attached one screen from 10.13. Part start from:
"[_REG] @000FD #002D..... untill ...Integer 0000000000000001" does not exist when boot 10.12.3.
Maybe this is a problem?

10.13 questions are off-topic in this forum.
Post separate thread in 10.13 forum.

And...
No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

I gave up on 10.12.4 and reinstalled 10.12.3 where with the exact same config everything works fine. I wonder if all Broadwell/HD5500 users experience this problem or if it's due to certain specs (e.g. a FHD screen or not being able to set DVMT-prealloc via BIOS).

Maybe this issue is worth a note/warning in the "[README] Common (some unsolved) Problems in 10.12 Sierra" thread.
Hi @apfeleimer, I have the same problem here and we have the same model of laptop. Did you manage to fix it? I have opened another thread and any help will be appreciated!

@JackLeeu Unfortunately I didn't manage to make my Laptop work with recent versions of OSX. I tried with 10.14.0 once it got out, but the black-screen-on-wake issue persisted. So I finally gave up and switched to Manjaro Linux.
Thanks for your reply.
That's too bad, I have almost read all the posts about wake/sleep issue on tonymacx86 but no solution found. It seems this problem is unsolvable.
