Thank you so much for your inputs, everyone ... > If Nvidia is properly shutted down, the only big issue lasted is a bad Skylake power management in Linux (going no deeper than package c-state 3), but then almost any Skylake laptop is not the best choice.
Wasn't Skylake bad power management supposed to be fixed with kernel 4.8? I'm not saying it is, but I saw the announcement by the mighty Linus himself quoted and reposted everywhere ... > Stay far away from it if you are a Linux user.

Well, that's my dilema - I've read about the issues and the shitty Dell support, on the other hand 7566 is a real price breaker - i7 with 8 threads, nVidia 960 4gb,8gb ddr4, 1920x1080 display and 128 gb ssd + another 500gb hdd for the price of 1100$, you won't find much competion there, at least not where I live, and I want to also use it for occasional Win gaming, although I can't stand Win for more than game launching. I could get the same configuration Linux certified, but it's about extra 200$, and I would have to ship it from Germany as there is only a few shops that sell Linux certified laptops around Europe, I live in Prague, and it's not exactly a manufacturer with a shop around the corner, so in case of warranty repair it's going back to Germany. With the Dell, I can buy in my favorite internet computer store. Then some people say it sucks with Linux, others say it actually works pretty fine for them, especially with the latest kernel version. Most of the issues looks solvable, more or less, except of the fan issue, but again, some people don't experience it, one guy was actually claimimg the other day that 7559 worked for him almost out of the box with Debian-testing, no issues whatsoever, so I'm kind off being torn appart. In the end, it's a little gamble, I guess ...

When I first boot up the machine the fans are off. However, after the laptop warms up under normal usage, the fans kick on and then never shut off again. Even when the CPU cools down to below 35c, the fans will continue to run. If I suspend the the laptop, and then immediately wake it up again then fans are once again off, until it warms up again. So essentially, once the fans start they don't seem to ever shut off. Fans seem to work normally under Windows 10. They turn on as needed, and then turn off once the laptop cools down. I've tried the various BIOS updates that Dell has released, without success. I am currently running Dell's latest BIOS for this laptop (v1.1.8) Below is the output of lm-sensors showing the fans running when the CPU is at a cool 35c dell_smm-virtual-0 Adapter: Virtual device Processor Fan: 1925 RPM Processor Fan: 2143 RPM CPU: +35.0°C GPU: +1.0°C SODIMM: +49.0°C ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-28-generic 4.4.0-28.47 ProcVersionSignature: Ubuntu 4.4.0-28.47-generic 4.4.13 Uname: Linux 4.4.0-28-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bob 1709 F.... pulseaudio CurrentDesktop: Unity Date: Wed Jul 13 19:18:45 2016 HibernationDevice: RESUME=UUID=14de580b-76f3-47e4-9850-fe7637f9ff77 InstallationDate: Installed on 2016-07-13 (0 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: Dell Inc.
