System Boot: ACPI Error: [_UPC] Namespace lookup failure

Hi,

I'm new to linux and arch. I'm happy that my first linux and arch installation was successfull (dual boot with windows if that matters).

I'm now trying to fix some boot errors. Every time I boot I got the following ACPI errors. I searched about it, but I'm not sure what to do or even if the solutions apply to my kernel version.

Linux Version:

[    0.000000] Linux version 4.13.7-1-ARCH (builduser@tobias) (gcc version 7.2.0 (GCC)) #1 SMP PREEMPT Sat Oct 14 20:13:26 CEST 2017

Do I need to worry about the ACPI errors or is there a fix available? The system boots anyway...

I appreciate any suggestions.

Re: System Boot: ACPI Error: [_UPC] Namespace lookup failure

Ignore them.  ACPI is a great concept, but the vast majority of consumer junk designed for Windows are extremely buggy.  As long as Windows boots, who cares about standards, Right?

This is just a small piece of dmesg in journalctl it looks the same. Any kernel, the same string of information. I do not know what to do anymore myself.
This is the laptop model Hyperbook N85S.

Still a screen from the start of the system System start.
