[Bug 1504751] Re: [HP Probook 4510s] Fan at full speed after suspend


Davide Depau, the next step is to fully commit bisect from kernel 2.6.35
to 2.6.38 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit

Thank you for your understanding.

  [HP Probook 4510s] Fan at full speed after suspend

Status in linux package in Ubuntu:

Bug description:
  When I turn on the PC, the fan runs normally and I have no issues at
  all. However, if I suspend the computer and resume it, the fan runs at
  full speed, regardless of the actual internal temperature. This is
  very annoying in libraries.

  This bug has been around for years, I just didn't need the computer in quiet places back then, so I never reported it.
  I believe it didn't happen with Maverick.

  I'm running Ubuntu 15.10, with Linux 4.2.0-14-generic x86_64
