    The idea is that, if it's safe for the hardware to run hot, then it matters whether the thermal tolerance of the human's lap has become the limiting factor.

    Currently, it is thermally throttling to a value that won't cause problems if your laptop is on your lap.

    Think of this like boost clocking. If the system detects a certain situation, it can allow extra performance within the confines of that workload's characteristics. (being safe to run hot in the thermal throttling case, being a single-threaded workload in the boost-clocking case.)

      While I understand the reasoning of a corporation designing their product with mentally challenged people in mind, how about letting people disable this mistake of a feature from BIOS?

      Also, huge thanks to Intel for implementing such a feature in a way that's this broken.

        Doesn't work on my 2018 ThinkPad L380 Yoga, so I wouldn't call it a solution for all.

          Since when did Linux become a corporate project? If it is important, the community should maintain it. Frankly the Linux developers are potentially much smarter than Intel developers.

          We should stop putting corporations on a pedestal

            >> These settings are used for determining between on-desk and on-lap behavior for trying to ensure that the laptop doesn't become too warm should it be on your laptop.

            I'm sure this would trigger a recursive loop!

              Did you try?

              Which CPU does your laptop have btw?

                Great job at disregarding the actual facts, Linux is affected by this and Windows is not. You can complain about thermals on ultrabooks in general, but the issue being talked about is specific to operating systems that don't have DPTF support from Intel.

                There's several things wrong with this post.
                1. This isn't something that can simply be maintained by the community, this stuff is not upstreamed and to my knowledge not publicly documented. You're essentially saying that volunteers should be able to reverse engineer this in their spare time (it's not trivial at all) and then also keep up with the pace of consumer hardware/firmware churn.
                2. Do you not realize that Intel is one of the largest contributors to the Linux kernel? Many Linux developers are also Intel developers, and either way it's insulting to play the "who is smarter" game.
                3. Linux contributions have been dominated by corporations for years, if this is a surprise to you, then you simply haven't been paying attention.

                  Just wondering how this lap detection actually works.

                    I did try, 2x in the last couple of weeks to be exact. My ThinkPad L380 Yoga has an Intel Kaby Lake R CPU.

                      I will remember that when the next release of Clear Linux comes out.
