Thanks for your quick feedback, Christopher. I'll do what you suggest. Am new
to this Bug reporting process, but the documentation looks good.
I am assuming that by submitting a new bug report that I will be getting a new
bug number. I'll attach that one to this thread once done.
I checked my
Richard Trabing, it will help immensely if you filed a new report with the
Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux
Please feel free to subscribe me to it.

Title:
Lenovo helix 2nd gen does not wake up from suspend
To manage
Hi, I just wanted to keep this thread alive, as the bug seems still to be
present. I recently tried suspend with the Helix 2 and Ubuntu 16.04 and can
confirm the same behaviour.
This issue is being tracked on the kernel bugzilla:

Are you saying that none of the pm tests failed?

Johan Bernhardsson, to advise, that little piece information provided is
not terribly helpful.
Despite this, you would to perform a memory test to confirm you don't
have bad RAM.
If this test passes, then you would want to review the recently updated
suspend debugging article
Using linux 4.5-rc5. same result.

A did a test to see if freeze would work. And it does work better than
suspend. Only snag is that it only works with a keyboard connected as
the keyboard is the only way to wake it up. The power button is still
not activating anything

I tried 4.4 and the bug is still there. And the debug doesn't reveal

Johan Bernhardsson, unfortunately, that didn't provide the root cause.
However, a newer mainline kernel has been released (4.4) and the suspend
article has been updated.
Hence, could you please test with the latest kernel and provide all
items of information?

so i have tried with pm-suspend, suspend from gnome3 and suspend on
inactivity. All results in a laptop that i cant wake up with lid switch
or power button.
I attached wakeup and dmesg.txt from the latest attempt. Debugging with
pm_trace reset the systems time.
