Recently got X2100 from Jacky. AMA

[napalmnorm]

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?

[jwise]

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

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

Jacky just shipped me an x200s lcd screen, instead of the x2100. Did anyone (besides the OP) actually receive a laptop?

[jwise]

My x2100 came from Jacky.

Hello Jwise,

first off, thanks for the wonderful work you did on the V25 bios with EC patch.

I am a windows 10 guy learning linux at the moment.

Would you mind sharing specific instructions on where to download Flashrom, then how to use it to Flash your V25 bios?

I can't seem to find instructions on how to do so and it seems no other flashtool will work for the X2100.

thank you again.

congrats on your X2100. the 13.0 inch 3:2 panel must be amazing. Have you tested and used the USB Type-C for charging? does it work flawlessly? thank you.

Got mine from @xytech with 1920x1200 screen - the one I asked for.

// But now I am actually thinking about changing it to 12.6": this one does not support PSR == extra 3 W or so in idle.

Hiya, would you mind de-crypting it a bit? What is PSR? What is 12.6"?

Hi.

Sorry, I meant I got one with 1920x1200 12.2" screen, but there are also 12.6" 2880 x 1920 and 13.0" 3000x2000 panels you could install (sacrificing the webcam). Initially I decided to go for 12.2" because it's matte (and I love matte panels) while 12.6" and 13.0" are glossy and because of all those zoom calls that require webcam. However, now I am not so sure I need it: webcam quality is pretty poor and upgrade options seem to be limited.

PSR is "Panel Self-Refresh". Usually for each refresh GPU transfers the screen contents to the panel, many times a second (e.g. 60 Hz) which consumes around 2-3W. PSR allows the panel to do the refresh itself, so the CPU sends the data only when there are updates. So if your screen is mostly static, it helps you to save some power, those 2-3W.
12.2" panel does not support PSR, while 12.6" and 13.0" do. And that's the second reason why I am thinking about changing the panel.

Quick question: what are your thermal readings under the regular load? Are you using NVMe SSD or SATA 2.5"?

I am using NVMe and it seems to be just on top of the CPU in x2100, so the front-left side of the laptop, under the palmrest, gets pretty hot, around 50-55 C for the CPU and up to 60 C for NVMe. Does it match yours? I am sort of worried about my SSD and I am thinking about switching to 2.5" SATA SSD instead.

My NVMe gets hot when it gets used, otherwise it's 40-50. I doubt you can optimize much with location, and SATA will be cooler just by the virtue of being 5x slower.

Recently got an x2100 from Jacky. Does sleep work when closing the lid? When I close the lid, it does not sleep.

[chakaponden]

Please run Geekbench 5 benchmark and post the results here. Thanks

Yes, it does.

This is with TDPs set to a "conservative" PL1 of 10,000 and PL2 of 20,000.

You'd obviously get better results with factory settings of PL1 23,000 and PL2 25,000.

I find these settings are snappy on most of my workload, though.

But it's just OpenCL result. Could you post CPU single thread and multi thread results?
