I've bought a new Dell Inspiron 5567 with an i7-7200U CPU (Kaby Lake) just yesterday, and it's a pretty decent machine.
After getting it from the shop, I installed my old Samsung SSD (an 850 EVO) into it, replacing its original Toshiba HDD, containing my old install of Arch Linux from my recently dead laptop (whose motherboard died).
Everything seemed to run fine without any issues under AC. The problems started when using the battery. The computer started randomly turning off (without any warning, pretty much as if someone turned off the power) while doing totally normal things (like browsing the internet or such). After this happened, I tried pressing the power button, and the machine turned on just fine, with its battery exactly at the same percentage it had before crashing, and with normal acpi reportings (except from pretty random estimates (I guess this were due to a not yet calibrated controller).
The journals are perfectly clean - nothing had been reported there.
After this happening a few times (within a range of time from a few minutes to half an hour before dying), I resigned into having to RMA it, and I placed back the hard drive with Windows.
And then I thought, "I've never tested this computer with Windows. What if..."
And here I am, writing from Windows, after doing almost a complete power cycle of the battery. No kind of issue whatsoever, nothing weird happened. This machine works perfectly under its own battery on Windows 10.
Can this be some sort of weird ACPI bug? Maybe the kernel has issues with this machine firmware? I was using the latest kernel from the linux package, and Kaby Lake is pretty new.
I'm starting to think this machine is fine, and there may be a problem either with 1. the SSD 2. the Linux ACPI stack.
What do you guys think?

Don't need to guess. https://wiki.archlinux.org/index.php?ti … no#Journal
1. Swap arch ssd back in
2. boot arch, trigger power off
3. reboot to arch and :
journalctl -b -14. show us this log with pastebin or similar
Is system up to date with a -Syu? What are the temps like? Did you have powersaving enabled? How? What is output for
uname -aOffline
I really need to get some work done, so I'm stuck with the HDD until I decide if this unit should be RMA to Dell.
But after using it the whole day long with AC and battery under Windows, I'm getting more and more sure that this machine is OK.
PS: The kernel was the last available in the repos (4.8.12-3).

If you want to experiment try the kernel parameter
acpi_osi="!Windows 2012"https://askubuntu.com/questions/28848/w … x-do/50776

I just found this on a quick google search after my laptop scared me doing the same thing. Just bought a new HP x360 spectre 13" with the new 7th gen core i7 (model # 13-W013DX). Dual booted with Ubuntu 16.10 (for the new kernel, which from my understanding was needed since this cpu is so new), so please excuse the different flavor of linux. In fact I have never used arch..forgive me if this is taboo enough to be considered spam here...I just think we have hit a similar vein.
My machine just randomly completely went dead about 20 min ago, like the battery was pulled dead, no warning or anything stuttering, nothing. It was on battery power, but not near dead. I tried to boot for a sec, didn't seem to work so I plugged in the AC and booted it up. The fact that I just dropped 1k on this machine had me wetting myself, ergo here I am.
uname -r returns kernel 4.8.0-30-generic. I am relatively new (but absolutely loving) linux so I beg my pardon. After setting up Ubuntu I did go under Software & Updates -> Additional Drivers and selected 'Use Processor microcode firmware for Intel CPU's from intel-microcode(proprietary)'. Otherwise that would be left at 'Do not use the device'... The device is listed as Unknown:Unknown...but I am assuming it is the CPU?
I am assuming this has to do with the CPU, would that be accurate? While in windows I haven't had this problem, only happened this once in Ubuntu on battery power. Anyone have info on this problem, if it is some kind of bug, and if I should be concerned for the safety of my beautiful machine? I need linux, for web dev and for life, can't stand windows (although it is dual booted with windows for accessibility purposes), so should I be hopeful everything will be okay?
Also this laptop uses USB C thunderbolt as charger...might have something to do with it?
