Title:
[Lenovo ThinkPad R61i (7650)] Fan not speeding up on high
** Description changed:
I'm using a Lenovo R61i (type 7650D6G), with Ubuntu 14.04 and up-to-date
BIOS. The fan speed is well controlled on low temperatures, i.e. around/below
50°C, staying between 0 and 3000RPM. The problem is that under a higher load my
cores can reach higher temperatures,
Reducing power consumption does in effect lower the temperatures (like simply
working on battery power does). I've tried thermald, which kept the cores about
5°C cooler, but didn't speed up the fan (it's not set to do so). I didn't try
the tool to increase fan speed, since it's for Dell
Andre, how about using fancontrol as per
https://help.ubuntu.com/community/PowerManagement/ReducedPower#fancontrol
(I just added it)?

Yes, that would be the best workaround in this case! Thank you for

Andre, could you please comment to if utilizing the following provides a
WORKAROUND via
https://help.ubuntu.com/community/PowerManagement/ReducedPower ?
Anders Hall, that's not how bug reports work. Despite this, so your hardware
and problem may be tracked, could you please file a new report
Yes, same problem with the latest (today) development release.

Andre, for regression testing purposes, could you please test 12.04.0

Before Trusty i was using Precise, but actually I really couldn't say,
since my use of the laptop was much less intense than now, but I never
had temperatures problem. By the way I could test the live version if it
helps.

Same Problem on Lenovo Thinkpad X301.
Workaround: Using tpfanco (Thinkpad Fan Control) and setting fan speed to
full at a certain temperature.

The difference is essentially the machine model, although both bugs
feature several different models in the comments. I reported this bug
following the advice in comment #152 from Bug #751689.

Andre, thank you for reporting this and helping make Ubuntu better. Could you
please test the latest upstream kernel available (3.15-rc7) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
I am really sad, I tried to boot with the following kernel:
linux-image-3.15.0-031500rc7-generic_3.15.0-031500rc7.201405251935_amd64.deb
and the result was losing the screen functioning. I tried to boot twice, but
both times, after a really ugly green stripes screen and Ubuntu loading for
