Thanks Alan Pater. Please mark this bug as "Won't Fix." Alan's explanation is sufficient to me (the original reporter.)

Looks like you have run into the infamous CPU frequency issue. http://www.thinkwiki.org/wiki/Problem_with_CPU_frequency_scaling Solution is to make sure you are running with high quality AC power. Workaround is to edit /etc/default/grub Find the following line and add processor.ignore_ppc=1 so it looks like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.ignore_ppc=1" then sudo update-grub && sudo reboot.

Dac Chartrand, for regression testing purposes, could you please test Lucid via http://old-releases.ubuntu.com/releases/lucid/ and advise to the results? ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246793 Title: Battery charging slows down laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1246793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry, to be more "Precise" :) I did in fact install Precise on this laptop. (2012-06-12) but I don't remember having this problem. I had both a desktop and a laptop at that time, and I was using the desktop tower more often than the laptop. I upgraded to Quantal and began using the laptop more often when 12.10 was released. I first notice the problem on 2012-11-23. Executive summary: Cannot confirm. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246793 Title: Battery charging slows down laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1246793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, this issue has occurred for me since Ubuntu 12.10 The workaround is to unplug, and then quickly replug, my laptop.

Thanks for the reply. I am unable to test kernel-unable-to-test-upstream due to incompetence. Sorry. Yes, the bug has been around for a while, it also affects other distros, ie. some comments in Bug #887793 (Comments 80, 81, ...) are related to this problem.

Did this issue occur in a previous version of Ubuntu, or is this a new issue? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
