Re: Bad CPU Performance X380 Yoga

@someotherguy, thank you for pushing the whole issue on the Lenovo side. Too bad this switch has not been included in the WMI for the 1.20 Version, I mean, I can't tell my users to enter bios setup and enable this option... Smiley Sad Hope this comes out, soon.

 

Also thanks to my technical account consultant for the help, I think you are reading this Smiley Wink

Yep, in BIOS > Config > Power > Adaptative Thermal Performance > Extreme CPU performance

Item Specific Help:

 

Highest CPU performance.
When enable this item, Scheme for AC and Scheme for battery will be disabled.
The item will affect Fan sound, temperature and battery life.

 


So in that option, what setting should we choose to fix the problem?

Re: Bad CPU Performance X380 Yoga

Maybe we should be clearer when we're talking about fixes for the performance issue and fan sound.   Maybe address that in a separate thread.

Re: Bad CPU Performance X380 Yoga

I can confirm the 1.20 BIOS update does not resolve the issues with the CPU performance.   Even with the Extreme CPU settings enabled, the CPU throttles to .4GHz frequently.

Re: Bad CPU Performance X380 Yoga

What are the settings that are recommended for each setting?  I set to normal and I am hearing the fan constantly still.

Re: Bad CPU Performance X380 Yoga

I'm not 100% sure we're out of the water yet on this.

 

We installed the 1.22 BIOS on a new X380 and with the Thunderbolt Security in the BIOS being set to No Security, the Thunderbolt 3 dock is still prompting for user authentication (which is asking for admin rights).

 

The release notes make mention of changes to Thunderbolt, is anyone else seeing this?

Re: Bad CPU Performance X380 Yoga

I can't really judge this, because we are just using the "simple" USB-C Docks on the X380. 

 

However we are having this issue with the P52 and its Dock. Its just a pain in the ass with those USB-C Type Docks. Nothing on those did work out of the box, there were some firmwareupdate necessary to make it actually work, and Admin rights for the first time docking the device. I just dont understand how issues like that can come to the customer. I mean, we are not talking about a 500$ laptop with a 39$ USB-C Docking solution designed for a home user.

Re: Bad CPU Performance X380 Yoga

I've installed the 1.22 BIOS update and still have the same problem.  My CPU clock speed very consistently drops to .4Ghz, which greatly impacts performance. Extreme CPU performance is on.  Is there anything else I should be looking at or does it just come down to this update didn't fix the problem (or maybe wasn't intending to)?
