Sorry but no. Ask Lenovo staff to do that.

 

The mystery drain occurs on S3/S0ix ( just happens to be less ) and *runtime*.

IOW, if we find what it is on either mode, we'll fix it all.

 

But I stop posting about it, including S3.

 

Good luck waiting for Lenovo to fix any of this.

 

Best Regards,

Gabriel, thank you so much for your work.

 

What you have done so far for the community and the users having this problem is really admirable. I am kind of worried, that if you will leave this thread, the problem will freeze forever as the Lenovo FW team looks too busy dealing with other stuff or is not interested in the Thinkpad series problems so much.

 

It is already nearly a year from the start of this thread, a new generation of machines was introduced and there were only minor improvements in the BIOS. The most interesting fact for me is that you as an outsider know a lot about these problems and it seems that it could be easy to repair them according to your notes, but those guys at the FW team cannot solve them.

 

Also, Mark said that he informed his management about these problems, but so far nothing has changed.

Do what? Lenovo staff don't control what thread you post on. I don't understand your objection. If S0ix troubleshooting occurs on a different thread then people can subscribe to either or both. Everybody can get what they want. Otherwise everyone has to be notified about S0ix kernel compilation chatter.

I tested with the latest kernel on Fedora, there's some improvement but it still seems high to me (I lose more than 10% overnight, around 0,494166667 Wh) :

Just curious, how is CONFIG_INTEL_PMC_CORE set in Fedora?

Also just grep for CONFIG_HSA_AMD, 5.13 only has one option, 5.14 will gain one more.

Grepping for CONFIG_HSA_AMD_ won't match CONFIG_HSA_AMD :)

But they can split the thread and ask for help or numbers, right?

It's nice to see fixes/enhancement in Fedora kernel, but I'm also on Arch. Does anyone *know* whether/how/when these will be ported to upstream/kernel.org? I'd be happy to just receive a pointer on how to search for that myself.

Exactly my question as well, even I am on Arch btw
