Occams Beard, thank you for reporting this and helping make Ubuntu
better.
In order to allow additional upstream developers to examine the issue, at your
earliest convenience, could you please test the latest upstream kernel
available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please
keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was
released upstream.
4) Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.
If the latest kernel did not allow you to test to the issue (ex. you couldn't
boot into the OS) please make a comment in your report about this, and continue
to test the next most recent kernel version until you can test to the issue.
Once you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this issue is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.
If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.
Also, you don't need to apport-collect further unless specifically
requested to do so.
Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
Dell Inspiron 7559 fans do not shut off once started, even when cool
Status in linux package in Ubuntu:
Incomplete
Bug description:
Running Ubuntu 16.04 on a Dell Inspiron 7559 laptop there appears to
be an issue with the fan control. 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
