Re:T14 AMD battery drain in standby (Linux)

2021-07-22, 11:54 AM

I made another attempt at testing X13 AMD with @osnix patches.

 

This time I disconnected the battery in BIOS and let the laptop sit for ~40 minutes. Also by @osnix suggestion I added following kernel boot parameters:

 

iommu=pt tsc=nowatchdog acpi_osi=Linux

 

After testing for ~2 hours I was able to reach 0.5 W/h in S0ix. There's also no long wait time when resuming from suspend. It looks like the more the laptop remains in suspend, the lower is the average consumption (seems like there's some high drain in the beginning, but then it falls down)

So the X13 consummation is in T14s range.

Re:T14 AMD battery drain in standby (Linux)

I wrote some weeks ago that I contacted the support with this issue - and we finally got an acceptable solution. Since I took the pragmatic approach and bought a Win10 license this might just help a small fraction of users (reading this). 

 

I'm running a X13 AMD Gen 1 with the BIOS version 1.32. Within the BIOS I set the sleep state to Windows and within Windows I set the option to go to "Ruhemodus" ("Hibernation" in English?) when I close the lid. With these options the battery looses just 1% within 20 hours. It is not perfect because it takes up to 15 seconds to restore everything, but it is good enough for me. :-)

 

Greetings, Peter

Question for the geniuses running the show here.

 

I'm a normal **bleep** person with some basic computer knowledge. How do I get this laptop (T14) for function normally in Linux?  

 

Do I need to compile my own kernel? Come up with a whole new operating system? Re-invent a whole new computing language that this piece of crap will understand? 

 

This is so ridiculous and pathetic. 

 

**bleep** this laptop, **bleep** you Lenovo, and any other person who is apologizing on their behalf.

I'm sorry but you got fooled into buying crap you don't need. Moreover, this is not a solution to this problem.

You can use hibernation in Linux, which saves the image to disk and shuts down the box. That will consume

almost the same energy as S5, so 1% in a couple of days, you don't need Windoze to do that.

 

Also, the issue is real and NOT limited to S3/S0ix, the power consummation applies for runtime on battery, and depends

on options and devices that are enabled or disabled in BIOS. This is what I'm investigating right now, on top of S3/S0ix

issues and BIOS(firmware) bugs.

 

Best Regards,

 

Gabriel

You can start with compiling an own kernel and apply some known workarounds for BIOS bugs.

 

It looks like we are on our own regarding the power drain.

 

Best Regards,

Well, it looks like we are not alone :)

Some Intel machines enter the party :)

I was being facetious. The average user should not have to COMPILE A FUUCKIG KERNEL!!!!!!!!!!

 

What a complete joke.

I am hitting the wall :)

getting this error:

make[2]: *** [debian/rules:7: build-arch] Erro 2
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
make[1]: *** [scripts/Makefile.package:77: deb-pkg] Erro 2
make: *** [Makefile:1570: deb-pkg] Erro 2

Using 5.13.4 from kernel.org

Applied patch like this patch p1 < amd.patch

Altered .config to the settings @osnix pointed...

but POP! is not loving me :)
