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

2021-06-25, 20:16 PM

I also see BIOS was released to ThinkPad X1 Carbon 9th Gen, X1 Yoga 6th Gen

I observe that thread as they also struggle with performance issue.

I see two fixes that potentially could apply to our problem as I mentioned that could be related to sleep state.

 

<1.42>
- (Fix) Fixed an issue where WMI parameter of SleepState is wrong.
- (Fix) Fixed an issue where system performance may down unexpectedly while heavy load application is running with battery charging.

Yeah, those two seem to apply to our case too… don’t know how similar/different the BIOS implementations may be for the various devices; maybe it’s something that can be backported? Unless it’s something device specific to those models…

Dear customers

 

Sorry for causing troubles with T14s performance.

We will release new BIOS where similar fix with ThinkPad X1 Carbon 9th Gen, X1 Yoga 6th Gen is implemented.

Currently test is ongoing for new BIOS and we estimate release date as middle of July.

For the last week or so, i have not experienced the problem to anywhere near the same degree.

 

I think I've only had some Windows Updates.

 

Anyway looking forward to the BIOS update.

Wow, this BIOS update could be huge; specially if it fixed all these issues as people on the other thread are reporting!

 

Fingers crossed this will be the definitive update we’ve been longing for! 

thanks Lenovo for taking this seriously and providing a fix, better late than never!

Sent my p14s gen 2 in for repair and they've replaced the CPU, still waiting for it to come back to me but I've noticed there's been a new bios released on the 25th for the ThinkPad P14s Gen 2, P15s Gen 2, T14 Gen 2, T15 Gen 2

 

Version 1.37

(N34UJ06W)

 

Has anyone tried it out?

Yes, I installed it My model is 20VX000LRT In the changelog I saw nothing about performance and sleep I temporarily disabled S0 sleep and installed hibernation, it saved the battery and the temperature, until the fix will appear, so I have no time to enable it back and test it. Also the bad thing is that all display settings (include color profiles for my 4K display) was missed. And I get error when I try to download color profiles from Pantone software. I think I'll create separate branch for this issue Please answer if the CPU replacement helped, I think it will be the best fix, if the problem was here.
