Additional info for comment #9: according to reports on 4pda forum S3/S4 behave erratically with Windows too, so probably there is issues with BIOS. What works here is Windows Connected Standy and Linux Suspend Freeze. Maybe BIOS issue could be workaround somehow to make S3/S4 works too, not sure about this.
Christopher, with Linux 4.7: S3 not working at all, same behaviour as described in original bugreport description. Patches from https://bugzilla.kernel.org/show_bug.cgi?id=102281 required to make it semi-working, at least as it works with Windows. S4 - on wakeup system trying to start but then reboot tablet. Again, with Linux 4.4 and patches from https://bugzilla.kernel.org/show_bug.cgi?id=102281 hibernate works, but with some issues, for example WiFi and LTE not working after wakeup and reboot is required to make it work again. So, to sum up things, I think making powerbutton working, so people will able to use at least suspend freeze mode, is goal that worth time. Is there anyone at Canonical who could review patches from https://bugzilla.kernel.org/show_bug.cgi?id=102281 to submit it to upstream?
