[Bug 563156] Re: 1002:9553 [Dell Studio 1555] laptop runs hot, shorter battery life, fan always on


shinyblue, 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>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) 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:

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

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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

  1002:9553 [Dell Studio 1555] laptop runs hot, shorter battery life,
  fan always on

Status in “linux” package in Ubuntu:

Bug description:
  On Karmic (2.6.31 kernel) my laptop ran silently (no fans unless
  really put through its paces), had long battery life (3.5 hours), and
  was cool.

  Since upgrading to Lucid beta-2, it runs hot, the fan is always on
  (from cold start it's off, but quickly comes on and stays on) and
  battery life is less than 2 hours.

  Lucid Kernel: 2.6.32-20-generic #30-Ubuntu SMP Mon Apr 12 15:20:57 UTC
  2010 x86_64 GNU/Linux

  Laptop: Dell Studio 1555 with ATI graphics (but using OS driver).

  Happy to help try things -- be great to get my laptop working properly
