Re:T14s extreme throttling (<0.5ghz instead of 3-4.5ghz)

Same here with my T14 Gen 1. But it started right after update from stock to 1.17. So 1.19 doesn't fix or break something new in terms of fan 100% speed. I've already contacted Lenovo in few ways with no luck.

20T0001CGE, and for me the newest update is 1.15, but as I said I installed that update and no longer have any issues. Even the windows energy mode is now actually affecting the clock speed, which is new.

 

For reference, FurMark GPU stress test runs fine:

OK thank you I also have 20T0, but  20T0S0A800 (with 1.15)

And I can also run stress tests on both GPU and CPU without issues.

But then I put computer to sleep and make Teams call with couple people at the same time as I described above and CPU goes 0,19/0,29/0,39 GHz.

So I wouldn't be happy just yet :D It is a bit better with 1.15 but NOT solved yet (at least not for me)

 

And one interesting thing is that when I stress GPU, CPU clocks down (I don't have over 3GHz). This is interesting for me too.

Hey Slavikf1,

 

I have the exact problem described here in the forum.

May I ask where you were able to get the BIOS version from?

 

My Model is 20T0 (004PGE) and the BIOS version on the support site is 1.15.

I also contacted the business customer support, but same result.

Nobody is on their site aware of this problem and the recomendation is just some "update your drivers and adjust some windows power settings"

 

cheers

Hi @MacNax2 , I believe you have T14s. And @Slavikf1 has T14. That's why there is a mess in bios versions here.

@budedub oh, yeah. Sorry and thanks for the correction! I temporarily switched back to my T480s. T14S is not usable with these issues :( I will keep you updated here what the support tells me and if they fixed my problem :) what they told me so far: 1. turn off the quick start option: (See attached file: Instructions - Disable Quick Start on Windows 10.pdf). 2. write 'Settings' in the main search box of your device and follow these steps: Update and Security > Windows Update > Update. 3. After that, update all the drivers of your device: https://pcsupport.lenovo.com/gb/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14s-type-20t0-20t1/20t0/20t0004pge/pc1n6mjb/downloads/automatic-driver-update 4. perform the steps from the following attachment: (See attached file: Power-Manager Error.pdf). (Uninstall Lenovo PM Device and Lenovo Power Manager and delete also the driver. then download and install https://download.lenovo.com/pccbbs/mobiles/n2hku67w_x64.exe )

Hi I also have cpu problems on my Lenovo ThinkPad T14s,
At my pace it is always running at turbo speed, so the fan is running loud so the battery is also empty in no time.

Good to hear i'm not the only one with problems, only now a solution ...

Have you tried to slide the slider in Power Options icon on taskbar from Best Performance to Better Performance?
