I would like to keep working with ThinkPad team to understand what it is about the power plan that causes this behavior, before I consider to provide a plan to import.  I don't want to cause some other problem by trying to work-around this one, so I feel like I should get some more information first.  Also, I'm about to go away for the holiday weekend so I probably won't be on the forum again until middle of next week.  Thanks for your patience.


You're right, it's better to be cautious.

 

Enjoy your Easter break.

Re: X1 CPU frequency pegged at max

@someotherguy, one other thing to send along to the team that they may not have considered:

 

Because keeping the CPU pegged at max frequency eventually causes it to overheat -- this is why the fan keeps turning on -- it also means that when it's hot enough it steps down the speed, usually in my viewing to the high 2GHz/low 3GHz range, while it cools down.

 

This is important, because in a "normal" workload when you do something CPU intensive, like open a new web page or a new application, there is thermal headroom for the CPU to switch all the way up to 4GHz to satisfy the request. If the CPU is already overloaded and stepped down to 3GHz for thermal constraints, what happens is that the perceived user performance can actually be *less*, not more. Only for situations where the CPU is constantly under stress is staying pegged in burst mode the best idea. The latency in stepping up isn't *that* high.

I have been dealing this fan problem for weeks and I kind of accept your design. However, since the CPU keeps full clock speed when idle, it is easily get hot. Consequently, if I really need it to do computing, CPU has to lower clock speed, increase usage percentage and fan working crazy. The ironic thing is, such high performance setting does not make the laptop performs high but make the idle status performs high. 4.1 GHz (3% usage) when idle but 3.6 GHz( 36% usage ) when working, does this seem like a reasonable design? The extra $185 for i7 8650 is only to get a higher idle CPU clock?

Keep in mind that unless you paid for the professional services warranty, Lenovo will not give you *any* support, *at all*, about anything related to software -- including their own drivers and firmware. I mention this because, not knowing what else they may have tweaked in their image, you know, for the better, the earlier solution of simply installing vanilla Windows 10 actually doesn't sound like a bad idea. I believe these days the Windows license gets registered to your Microsoft account so it's really a question of getting the installation media...

Re: X1 Yoga 3rd gen. CPU frequency pegged at max

Sorry if this is out of topic but I can report the very same problem on x1c 6th gen(I was searching for a solution and found this thread).

Maybe @someotherguy can add this to his researches.

As soon as I'm back home in 2 days and Iwill try throttlestop to activate speedshift (if not already enabled) and see if it can solve the problem(read about this searching for a solution)

@Arjov

someotherguy already isolated the problem. It's bad configuration by Lenovo. He's working with the ThinkPad team to find a solution. So no need to try throttlestop or anything else, better to wait for properly configured power plans. Anything else would be a workaround, not a solution.

 

Good though that you mentioned that you have the same issue with the X1 Carbon, then Lenovo will know that they need to solve the problem for that machine too.

Happy to hear that! I just backlogged the thread, my bad.

Just my 2 cents worth, but I just got a new X1C and it has the same problem, when idle, not throttling down, pegged at 4Ghz...  (Lenovo image)

I took the plunge with my X1C Gen 6 and reinstalled Windows 10 :)

 

CPU is now throttling back as it should even on AC Power.  First laptop I never bothered reinstalling as soon as I got it, but well worth it.

What did you use to get the media? Just the official media creation tool? And any problem with the license?
