I just replaced my old Zotac Zbox with a new one and I am having some issues after installing Ubuntu 18.04.

The system is a Zotac Zbox Nano CI329 (Intel Celeron N4100, Intel UHD Graphics 600) with a 120GB Samsung SSD and 8GB RAM, BIOS is updated to the most current version.

The issue: when the system is suspended (doesn't matter if triggered manually or by automatic suspending after defined idle time) it does not wake up anymore. It does not react to a click of the power button or mouse/keyboard. You can use the power button to suspend the system but after that you have to unplug the power cord and plug it back in to get the system to boot up again. I contacted the support at Zotac and they haven't been very helpful. They just told me that I should ask the retailer to replace the unit... but I don't think that it would change anything. The physical button seems to work fine. I assume, it's more of a driver/compatibility issue. I tried all different settings concerning sleep and hibernation in the BIOS but that did not have any effect at all. And now I'm stuck.

So currently automatic suspending is disabled but I'd like to use that function because there is no need for the system to run 24/7, I'm not at home that much. The hardware might last a little longer if the system gets regular naps, I guess. ;) Sure, I can just continue to manually power down the system after every use.. but unfortunaty I'm the type of guy who gets driven nuts when something does not work as it's supposed to and I can't figure out why. I have spend many hours researching the issue via Google and forum search but I haven't been able to find a fix that does the trick.

I'm a beginner when it comes to linux... I have been using Ubuntu as mediaplayer (and to quickly check my emails or so and lightweight tasks like that) for a couple of years and I'm quite happy with it. However, I'm not very fit with the 'off-gui stuff', I tend to forget most of it before I need it again a bunch of years later when I set up a new barebone.

Does anyone of you have experience with that kind of issue? Any advice? :)
