(1) I did update the bios. Output from dmidecode reads now...
N17ET83W (1.83 )
12/02/2015
(2) I installied microcode 0x22 from "intel-microcode" package, version
3.20151106.1
(3) I disabled thinkpad_acpi
None of this or any combination thereof yields any improvement.
Hibernation does work, suspend does not work. Suspend can only be
initiated (and seems to lead to a substantial battery drain), but the
only way to return from suspend is a hard power-off.

Title:
Lenovo Helix does not wake up from suspend
Status in linux package in Ubuntu:
Confirmed
Bug description:
System goes to sleep, indicator does flash slowly as expected, but
there is no way to wake up (Power Button, Lid open, Enter, ...). The
only way to recover is to press power button for more than 4 seconds,
and then power on again. pm-hibernate does work.
Problem appears with 4.2.0-18-generic kernel, also with 4.4-rc2 (also
under Debian testing kernel 4.2.6-1)
Problem appears with terminal pm-suspend (with and without X running),
lid close suspend, gui suspend.
The “resume-trace” yields the following magic:
[ 2.228057] Magic number: 1:0:0
[ 2.228158] rtc_cmos 00:02: setting system clock to 2001-01-01 00:00:18
UTC (978307218)
(while without resume trace it says
[ 2.226884] Magic number: 7:269:577
[ 2.226985] rtc_cmos 00:02: setting system clock to 2015-11-30 09:33:06
UTC (1448875986)
)
The content of /proc/acpi/wakeup (with 4.4-rc2) is the following:
