throttled

Is it? Last time I tried to use t480, which is listed as officially supports Ubuntu, I had to use rather ugly hack to fix CPU throttling: https://github.com/erpalma/throttled It affects other models as well and not fixed up to this day (at least not by vendor) Lenovo had a post in their blog acknowledging it, but after some time it mysteriously disappeared EDIT: Lol, there are HN post about this "fix" happened few hours ago: https://news.ycombinator.com/item?id=35025838 By quickly checking comments seems like better solution is already available: https://mjg59.dreamwidth.org/54923.html

Not sure whether you are aware but this issue seems to affect different vendors like Lenovo as well who can't find a solution neither. The same issue is being reported all over lenovo linux forums as well and for example on https://github.com/erpalma/throttled/issues/255 you see lots of lenovo people reporting the same. I personally suffer the same issue on my X1G9, the best fix so far is the unload/load all related kernel modules one which makes throttling at least only drop to 1.2 Ghz.

Maybe https://github.com/erpalma/throttled can help

Unfortunately, "throttled" does not fix the problem on these particular models. See https://github.com/erpalma/throttled/issues/255

The solution is https://github.com/erpalma/throttled/ Been using it on various XPS laptops for years. Sadly it requires support for MSR writes which are being slowly deprecated by the Linux kernel. I believe the same should be achievable with thermald be I haven't been able to be bother yet.

A few things. The newer TrackPoint caps are not good. I actually had to order some 3D printed one from some Japanese guy. Also my Thinkpad T14 is throttling to the extent that I had to install tools [1] (?) that fix this problem. Battery seems to be bad as well. Intel by the way, I wanted to have Thunderbolt for an eGPU. [1]: https://github.com/erpalma/throttled

Lenovo might be known that way, but they are exceptionally bad at supporting Linux. https://www.notebookcheck.net/Lenovo-admits-ThinkPad-CPU-thr... As far as I know this issue is still not fixed so I have to use this hack: https://github.com/erpalma/throttled I’ve also had tremendous Thunderbolt-related firmware issues that could only be fixed in Windows. If you use Linux, there are much better options than Lenovo. I still use my T480 daily but I miss my old XPS 13, which gave me no issues ever.

I was currently shopping around for a new Laptop, and I really like the T series ones. Unfortunately, it seems they suffer from the throttling issue, which can be mitigated by a fix from the community [1]. I think Lenovo also released a fix for some models. All in all, it's a bit hard to know which models are impacted or not, and I don't want to end up buying one and having to resort to these kind of fixes to have it working correctly.

I also use a T480 as my main laptop and love it. Here are my notes & dotfiles for running Arch Linux: https://github.com/vesche/t480 One big item (which you'll see at the bottom of my install notes) is that intel chips in these thinkpads have a throttling issue. There's a nice python program to fix that, I run it as a systemd service on boot: https://github.com/erpalma/throttled

maybe this anti-throttling script[1] should help. I'm able to run at max CPU clock frequency at 85-90+ deg temps without throttling when doing CPU intense stuff (t480s, not carbon, but should work on carbon). [1]: https://github.com/erpalma/throttled

I think I can suggest the following to address some of these issues - Battery: A package called TLP should drastically improve battery life[1][2]. Thinkpad t480s with battery life ranging from 6-8 for browsing to 13+ with min-brightness and just playing music. Before TLP I think it was close to 5 max. - I'm assuming since X is crashing you're not using Wayland. I've noticed fractional scaling (which is a thing in Wayland) causes blurry text. This isn't an issue in X, but I've noticed if I mess around with custom xrandr config to customize stuff, I have issues -- i.e. total system lockup, reboot required -- with plugging in/out external monitors on to the fly. Anyway, a custom xrandr setup should make things a bit easier on your eyes.[3] - For CPU performance maybe this anti-throttling script should help. I'm able to run at max CPU clock f

I've used Linux since the early 1.x kernel versions, but for my next laptop I'm thinking about switching to a MacBook. Not because of the software (I prefer Linux to macOS), but because of the hardware. Apple seems to be the only manufacturer that so far escaped the race to the bottom and which still produces somewhat premium hardware. I want: a hidpi screen with lots of nits and a good contrast, a trackpoint or a huge touchpad, good battery life and somewhat light weight. In the past Thinkpads worked really well for that, but recently I had multiple issues with Lenovo hardware. I'm currently using a X1C3 and originally considered upgrading to a X1C6 or T480s, but given there are known issues such as the throttling bug (https://github.com/erpalma/throttled) that Lenovo hasn't fixed in over half a year I'm very close to giving up on Thinkp

The only thing that doesn't work with my X1C6 on Linux is the fingerprint reader. Everything else works. They fixed the sleep issue with a BIOS update. The only remaining issue is aggressive throttling of the CPU, which is fixed with this: https://github.com/erpalma/lenovo-throttling-fix

I'm not sure this is Thinkpad specific. I have a Dell Latitude 7490, same generation as the X1 gen 6, and I often see "Package temperature above threshold, cpu clock throttled", same as on my 6th gen X1 at home. And I don't push these machines, the heavy stuff run on a server. Also, the page with the fix [1] list a Dell XPS 9370. So it may just come with recent Intel based laptops. Personally I have no problem with Linux having a more conservative thermal threshold than Windows, on the contrary I prefer it that way. The few times I ran Windows 10 on these same laptops, I got annoyed by the fans spinning when I didn't do anything substantial. I'd rather have my laptop cool and silent (and still very reasonably fast for most things) than faster on heavy loads. To each their own, but I think silence and low temperature make sense for ultra-p
