Bug Description

I have an Asus S7F laptop and most of the times, the fan is not spinning at all. When booting in Windows 7, the fan works.
Temperature reaches sometimes over 80 degrees, so I had to put an additional fan next to my laptop just to keep it at 70 degrees. Any idea what could it be the cause? Unsupported sensor maybe?

simonez, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available (3.15-rc6) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.15-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Fan is working with latest mainline kernel. Funnily enough, when I rebooted using the 3.13 kernel, the fan was working. Probably the fan status doesn't get reset at reboot.

simone, the next step would be to fully reverse commit bisect in order to identify the fix commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

I have the same issue on toshiba satellite p50-b-10v. Sometimes the fan doesn't work, but if I reboot it starts to work normally.

I haven't found a pattern yet but I think it's related with suspending computer and alternate between power cable / battery.
