[Bug 689571] Re: cpu runs very hot even when idle

 

Jürgen Herrmann, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5

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

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

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.

Title:
  cpu runs very hot even when idle

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: linux-image-generic

  CPU (Intel i5 M 450) on Dell Vostro 3700 runs very hot, even when CPU-
  load is <1%. Temperature is 65°C when idle, rising to 75°C when under
  full load. Temperatures seem correctly reported, CPU is too hot too
  touch at this temp. Running Windows 7 the CPUs have a idle temp of
  35-40°C, also verified by "hand thermometer". according powertop cpu
  is 92.5% inc C3 wait and 95,8% running at 1.2GHz (half speed).

  Already tried several different kernels, oldest was 2.6.19 based. Also
  happens with ubuntu vanilla kernel.
