Jeff Zen, 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 (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: 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-v3.12 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. ** Tags removed: consumption kernel power ** Tags added: needs-kernel-logs needs-upstream-testing regression-release ** Description changed: What happens: Under Ubuntu 12.04, the system's power consumption is around 32 Watts idle, which is unbelievably high compared to the 12 Watts consumed by Ubuntu 10.04. I believe this could be a kernel problem. What should happen: The system's total consumption should be around 12 Watts. Software: - Ubuntu 12.04 LTS - fresh install Kernels I've tested are all affected: - 3.1.5 - 3.2.0 - 3.2.5 - 3.3.3 - 3.3.4 - 3.4.0-rc4 Hardware: - HP nc6320 - Intel Core Duo T2300 - Intel Graphics 945GM - - The bug is also present on the following hardware: (thanks airalcorn2) - - ASUS U24E - - Intel Core i7-2640M CPU @ 2.80 GHz (Sandy Bridge) - - Integrated Intel HD Graphics 3000 ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991694 Title: unreasonably high power consumption in precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
