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

2018-03-21, 14:47 PM

heard that the Lenovo support was bad but this is out of the line! 

 

On other note, the recent BIOS update (N25ET24W 1.10) seems to help on the Fan/Temp issue, give it a try if you haven't done so.

That's the BIOS build I'm on. Any specific guidance on what it's supposed to fix/help? I haven't noticed any difference. Going into Vantage and selecting Cool 'n Quiet still pegs at 4 GHz; using the battery slider in Windows also makes no difference.

 

As for support, I'm mad on a whole bunch of different levels, but the main one is that I've never heard of driver issues requiring a software warranty before (this is my first Lenovo) and had I known that there was a 30 day ticking clock on it I wouldn't have gone down their suggested path of using the forums first and waiting for someone from Lenovo to reply.

I'm sorry to hear about your experience, jefferai. That's beyond bad. I'm new to Lenovo but I expected their support to be good, at least for these expensive business models.

 

I filed a service request 48 hours ago, referring to this thread. Hopefully someone will pick it up, though so far I haven't heard anything.

 

Unfortunately, updating to BIOS 1.10 didn't help. I'm still pegged at or near 4 GHz and temps are still high.

I didn't do anything particularly, other than applied the BIOS update. The CPU temp is under 65 degree for most of the time, occasionally at 75 degree. Prior to BIOS update it was 75-85 degree.

zertank, were/are you also experiencing unnecessarily high CPU frequencies or just heat issues?

jefferai, have you tried booting from another OS? Do you see the same issues?

 

I have not been able to try so far but will see if I can load something on a USB stick and boot from there over the weekend.

 

If we see the same issues when booting from another OS, it's almost definitely a BIOS issue.

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

I might be zooming in on a solution. We need to play around with settings a bit more though to see if it's satisfactory.

 

I changed my Windows Power Plan settings to "Power saver". Then my CPU goes down to ~0.80 GHz at low loads, even with AC connected, yet I can provoke it to go to around 2.5 GHz with heavy load. That's not ideal, we want it to go higher, but perhaps there's wiggle room if we play around with the settings of the power plan?

 

I don't have time to do that now, it's getting late here in Sweden and I need to go to bed. But if anyone feels like trying, please do and report back here.

 

How to change the power plan? With Windows 10's Modern Standby on I don't see the standard power plans "High performance" and "Power saver".

 

To see them, turn off Modern Standby in the registry and reboot.

 

You turn it off by changing HKLM\SYSTEM\CurrentControlSet\Control\Power\CsEnabled to 0 (that's a zero).

 

You still can't directly choose Power saver but you can create a new power plan and base it on Power saver - and then choose this new plan (I called mine "My Power saver").

 

You should be able to turn Modern Standby back on (switch back to a 1 in the registry) and still have your custom power plans available after reboot, though you won't see all the options under "Advanced Power Settings". So I would suggest to keep Modern Standby off while figuring stuff out, and then turn it back on only after we've found a solution.

 

Let's see if this can solve things. I myself am going to bed.

Look in Task Manager to see who is using the CPU.  My 3rd gen x1 yoga is quiet.


I would be interested to know if your quiet X1Y3 does have the same issue of keeping the CPU at max frequency when plugged in. And if so, is thus a bug or a feature? 

 

In another thread it was noted that the the X1Y3 runs in low power mode when in tent/tablet mode by design, managed by the Lenovo Power Management service. I wonder if the behavior observed in the thread is also managed behind the scenes by the PM service.

joesixgig, I tried disabling the Lenovo PM service but nothing changed.

 

I've run out of ideas.

 

Since my X1Y3 is behaving as expected on the Power Saver plan, I suspected something was wrong in the Balanced plan.

 

I ran powercfg /qh to get a list of all power plan settings, including the hidden ones. I then identified any differences between AC and DC plans that could be relevant (not settings for screen brightness etc., but anything I figured could have anything to do with the CPU performance).

 

I modified my registry to make the AC plan look like the DC plan and restarted my laptop.

 

Alas, it is still pegged at 4 GHz.

 

That's it, I'm out of ideas.

 

For now, I've created to batch scripts, one that switches to the Balanced plan, one that switches to the Power Saver plan. That way I can easily make my computer go silent even when on AC. It's not ideal, as far as I've understood I am sacrificing snappiness by being on the Power Saver plan, but it's a temporary solution at least.

 

Meanwhile I am still waiting to hear back from Lenovo. It's been five days since I filed my report. I haven't heard anything but when I log in to their system, I see quite a lot of acticity history and from what I can tell they are now waiting for spare parts that should be delivered in about three weeks.

 

I'm baffled. Why would they order spare parts before contacting me and why would they even think that any spare parts could solve a configuration issue like this?

 

I will try calling them next week.
