[Bug 1602888] Re: Dell Inspiron 7559 fans do not shut off once started, even when cool
After much consideration I have finally decided to buy Dell 7566 - a Skylake 6700hq version (a successor of 7559 model). I am running Debian testing (Stretch) with kernel 4.8.0.2 with nouveau driver. After testing it for while I can now confidently say that in this configuration the 7566 model is not plagued by the fan issue - out of the box, lm-sensors show CPU operating temperature between 35 and 45 C with 0 RPM for fans on normal "office" workload. Fans only kick in when CPU temp exceeds 60 C and stop almost immediately once temperature drops below 50 - 55 C. Originally I suspected CPU fan sensor was not working correctly as it was constantly showing 0 rpm. I had to actually run some Android studio application build which taxes CPU fairly, to get the fans running. They ran for about 1 minute between 1500 - 2500 rpm and stopped almost immediately after the build had finished. The battery life is about the same in Win10 and Linux - approximately 6 hours on normal workload. I even have the sleep function working out of the box and install works without any problems (with the safe boot turned off). I don't know if this helps anyone, but if there are any potential buyers around here seeking information, I believe it is safe to say that 7566 is a safe bet with Linux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602888 Title: Dell Inspiron 7559 fans do not shut off once started, even when cool To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1602888] Re: Dell Inspiron 7559 fans do not shut off once started, even when cool
Just to clarify this for me, because I'm getting kind of lost in reading all the posts, both Ubuntu developers in this thread, and kernel developers in the kernel thread where this issue is reported are more or less blaming this on Dell firmware, am I getting this correctly? Concerning the Dell certified version of Ubuntu - Dell does not allow other users whose machine did not originally come with it to download, i.e. making it public to download, am I correct? I also have a question about the i8kutils - does it remedy the issue completely without side effects and is it dangerous to use it? I mean, it's not vendor certified software and it meddles with temperature settings for the fans, so if I really screw up the settings, can I potentially fry my CPU? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602888 Title: Dell Inspiron 7559 fans do not shut off once started, even when cool To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Peter, thank for clarifying things for me, I appreciate it. Also, have you tried the http://linux.dell.com/ ? It's kind of unofficial dell Linux support site. Or so they say ... >> Would it be illegal to release it?? Its open source anyway. :/ Sure, Ubuntu is open source, not sure if you can take parts of Ubuntu, change it and claim it proprietary. After all, I never read the license ... :) Anyway, I don't think they would make much fuss about it.

Dell has introduced a successor of Inspiron 7559 - Inspiron 7566 at the end of October 2016 - http://www.dell.com/sg/p/inspiron-15-7566-laptop/pd?oc=w51755724sgw10 .It has got the same CPU, GPU and display but comes with DDR4 RAM and SSD disk. It also has a new look, much uglier than 7559 in my opinion ☺, but in the end something I can probably live with ... Since it has been around for only a few days, there is virtually no information on how it works with linux, so I guess I can only extrapolate whether it's going to have the same issues as the 7559 and potetially higher risks since it has not been tested.

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.

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.

[Bug 1602888] Re: Dell Inspiron 7559 fans do not shut off once started, even when cool
Occams Beard, have you tested the fan issue with kernel 4.8? Here, you only mention kernel 4.7, but 4.8 was supposed to fix Skylake power management issues. I have noticed people having fan issues on other laptop models with Skylake, mostly i7 6700hq, (Asus, Lenovo), as well in Linux, so this points to the fans problem being a broader issue. On the other hand I see people here and the other kernel thread reporting that 4.8 alone has not fixed the problem for them (I have seen 2 so far). It would be nice to have more data in order to be able to clearly distinguish whether the 7759 fan issue is a Skylake problem alone, or if there is something else in play. I haven't found any reports from those other folks outside the 7759 linux community who previously had fan issues too, to see whether the 4.8 has had any improvement for them yet. 4.8 has only been out for about a month, so I guess there is not enough data ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602888 Title: Dell Inspiron 7559 fans do not shut off once started, even when cool To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
