Recently got X2100 from Jacky. AMA

#1 Post by napalmnorm » Wed Sep 30, 2020 9:28 pm

Recently purchased an X2100 from Jacky of Cnmod.cn with the i7-10510U and the 13 inch panel. So far, I love it. If anyone has any questions, I'm happy to answer.

I've owned several Thinkpads before (T60p, X60 tablet, W701DS, TP25), but this is my first "modded" Thinkpad.

Would be nice if you benchmarked your cooling system under prolonged load. Like viewtopic.php?p=847123#p847123

Running a quick test on default TDP settings with Prime95 running of battery power for 10 minutes (I don't have my adapter with me at the moment), it never went above 70 degrees.

I'll do a more thorough test at a later point.

It means nothing w/o actual consumed power (or frequency of all cores at the very least) being logged, as it could be throttling.

Do you know of decent, free software to test that? I'll try it out later, if you want.

How loud is the fan, and around what temperatures does it tend to kick in?

If you use my modded EC patch, you should be able to get power consumption data directly from the battery.

Does your mod work with the X210 too?

I think X210's EC is already capable of reading discharge rate from the battery. It's just X2100 that had that functionality disabled for some reason. I do have a PR in for L29Ah's repo that adds Vladisslav2001's patches to the configurator, though: https://github.com/l29ah/x210-ec/pull/2

As i already mentioned in that thread, you can use throttled or my script hosted at https://github.com/l29ah/intel-powermon

Yes it is, but the readings are all wrong, we apply a correction in coreboot
https://review.coreboot.org/plugins/git ... c86a51c84a

I thought your patches fixed that at the EC level

Nope. Out of the box, X2100's EC can't read discharge rate. At all. My patch just enables X2100 to read the discharge rate from the battery -- uses the same logic, I think, as X210 does.

I think it would be possible to do the coreboot correction fix. The only problem is that I run a 3rd-party battery that doesn't seem to have this problem! So I'd need to 1) be able to detect a correctly-behaved (misbehaving?) third-party battery, and then 2) do the multiplication to fix it in the EC. Part 2 is not hard to do but I think part 1 would take some work to do reliably -- and anyway, is a solution for a problem I don't have, so is something I'm not super motivated to do :) If someone sent me a first-party 9-cell battery that I could reproduce the issue on, I'd try to come up with an EC patch to fix it.

Hi,

the readings are always wrong (in the X210). it doesn't depend on the battery. If you post the output of

Code: Select all

upower -d
and/or the content of

Code: Select all

/sys/class/power_supply/BAT/charge_full_design
/sys/class/power_supply/BAT/charge_full
I might be able to tell

The X210 EC firmware directly reports the values it receives from the battery. Most X201 batteries appear to report incorrect values, but it's entirely possible that some third party ones using a different controller could provide accurate values.

...been waiting for quite a log time for my X2100, all this time a KingSener battery has been sitting here waiting. It will be funny if I end up discovering that KingSener has an advantage over genuine batts in reporting correct values :) I seriously think we should consider KingSener as a valid battery option for X210(0)-s, they are available, they are a "brand", seem to operate okay and if they also report better values..

Ah!
I stand corrected then, sorry.
I've seen around a dozen batteries, OEM and not, and none was reporting the real charge
