Thinkbook 13s Gen2 not working

[vtainc]

HI,

I understandt, that this is not a clear ThinkPad, but original tpfancontrol 0.62e works without problems, but controls only one fan ( 255 min, 0 - max )

TPFanCtrl2 is not working - writes to log, that it is not possible to read from EC register.

[Shuzhengz]

Hi,

Can you check if TVicPort is installed correctly on your laprop? EC read errors usually have something to do with it. The program also needs administration permission to run so maybe run it as admin.

It would also be great if you can specify your computer's specification (Model, specific CPU info, BIOS version, OS and build number, and the TPFC version) and include info in the log.

[vtainc]

Yes, tvciport is installed and working, because i'm using tpfancontrol 0.62e

[Shuzhengz]

yeah, but v.0.62e is "special version for Edge E520 only" (info from thinkwiki), so it doesn't confirm that everything is installed correctly

[vtainc]

yeah, but v.0.62e is "special version for Edge E520 only" (info from thinkwiki), so it doesn't confirm that everything is installed correctly

I know, that it is special version. But the difference is only that on almost all thinkpads fan can be controlled using speeds from 0 to 7, but in 0.62e speeds are controlled from 255 to 0.

I have tried to test tpfanctrl2 from the beginning, what I have done:

1. Reset win11 :D
2. Installed latest free tvicport.
3. downloaded tpfanctrl2, but anyway - same error message.
4. after this removed tvicport
5. installed tpfc_v062e - , reboot and it works :( , but tpfanctrl does't

[Shuzhengz]

Oh there's actually a 0-80 controll mode in TPFC2, so maybe you can try that. If you have Lenovo's Vantage software installed, make sure to disable the "inteligent" control mode as it messes with the EC in some situations.

I think the 0.62e version has different CPU sensors, but I'm not very sure (I can't find the source code for tha release). I'm happy to make a special release version, but I don't really have a way to test it since I don't have any machine that runs Windows 11 (that's why I put windows 11 as theoretically working but unsupported in the readme).

It would also help if you can specify your computer's specification (Model, specific CPU info, BIOS version, OS build number) and include info from the log.

[Shuzhengz]

3. downloaded tpfanctrl2, but anyway - same error message.

Can you inlude the error message (a screenshot and description would be fine)? I need to know where and what went wrong in order to debug it.

[vtainc]

After analyzing EC controller data I have found that:

147,150 - fan mode selection
14 - manual control
04 - bios

148 - fan speed 1 set ; 149 - unknown, seems to be, that this is raw fan speed, but i'm unable to guess how to decode it - it is only byte, but fan speed can be up to 9000 rpm.
151 - fan speed 2 set ; 152- unknown, seems to be, that this is raw fan speed, but i'm unable to guess how to decode it - it is only byte, but fan speed can be up to 9000 rpm.

168 - cpu temp
169 - aps temp
170 - crd temp
174 - bat temp
175 - x7f temp

I think the 0.62e version has different CPU sensors, but I'm not very sure (I can't find the source code for tha release). I'm happy to make a special release version, but I don't really have a way to test it since I don't have any machine that runs Windows 11 (that's why I put windows 11 as theoretically working but unsupported in the readme).

don't worry, 0.62e works like a charm on windows 10 and 11, tested. I also have Thinkbook 14, that runs Windows 10, but there I use another version of tpfancontrol - 0.63, because on that Thinkbook the fan i controlled from 0 to 7.

It would also help if you can specify your computer's specification (Model, specific CPU info, BIOS version, OS build number) and include info from the log.

[Shuzhengz]

Cool, I'll look into it later today

[Shuzhengz]

@vtainc Try this and see if this works (i can't test it because it breaks on my computer now, but it should work based on the data)

Hi,

Thank you for your time, but - no, it doesn't work. Same behavior as last time.

Maybe you need some additional data?

[Shuzhengz]

Yeah that'd be great

Can you enable the Log2File flag in the ini file for V0.62e, let it run for a few minutes, then send the TPFanControl.log file?

Thanks!

[Shuzhengz]

cool, thanks

[Shuzhengz]

I did some moe digging on the internet, but can't find the source code for 0.63e, so it's kinda hard to know exactly how to fix it :/

I think the problem is the EC registry being different on some systems. But the problem is I don't know where yours is, so I can't fix it (because I can't test it on my system).

But I did build antoher build to test tho, and see if it works (the registry is used for older generation ThinkPads). If it doesn't then I think you'll have to compile code on your machine and try to fix it (by changing the registry numbers in portio.cpp)

Thanks!

Attached: tb13.zip

[vtainc]

Tested. No, it doesn't work. Ok, I will try to compile the source code and see what is wrong. It was a very long time ago when I was programming something :). I hope that I succeed

[Shuzhengz]

Cool, good luck :)

(also you might have to add in the .ini file manually to the debug folder when debugging it using visual studio)

[vtainc]

After some time of playing I was impossible to get your version to work - seems to be, that there are some modifications used, that prevent your version to work on my laptop.

Bet I have good news - I found version on github, that works, I have made some modifications in the code and now it displays all temperatures correctly and I can control both fans ( with some problems :D ), but it doesn't display fan speeds correctly. - I really forgotten what is programming and I didn't know C++; Some time ago I had some experience with Delphi + asm, but this is long story. I will try to make this version for my laptop, but I think, that it will cost me more time, that I have :D + learning C++ from almost beginning.

Here is the unmodified code: https://github.com/Ede123/TPFanControl

in my version I have changed variables in fanstuff.cpp, because I have different offsets for temperature sensors:

#define TP_ECOFFSET_FANSPEED (char)0x84 // 16 bit word, lo/hi byte
#define TP_ECOFFSET_TEMP0 (char)0xA8 // 8 temp sensor bytes from here
#define TP_ECOFFSET_TEMP1 (char)0xB9 // 4 temp sensor bytes from here

and changed setfan function - implemented dual fan control. But yes, I' m only playing, without normal knowledge with C++.

Maybe, if you can see where is the difference, then you may try to fix your code, but if no, then I will try to fix my code when I will have free time.

[vtainc]

Also I think, you may include in your code tvicport.lib, because it is not included and I have found it in another repository ( included tvicport.lib, that comes with tvicport installer does not work, with vs 2022 )

[Shuzhengz]

Oh cool thanks! I'll look into it this weekend

[Shuzhengz]

i built another one from the one fan version, try see if this works

Hi!

Tested - no good news - doesn't work. Same behavior as always.

[Shuzhengz]

sad
I wonder if it's a problem w the second fan config in lenovos drivers
the p50 in the other issue has a similar problem (except the p50 just shuts off straight away, even when using lenovo's own diagnostic tools)

[Shuzhengz]

or it could be just we haven't found the correct ec address yet

[vtainc]

Yeah, but I have build, that is working correctly, but without your modifications. So, it seems to be, that the problem is not with ec address and there is some other problem.

[Shuzhengz]

sorry, i mean the ec address for the second fan (the first one should work because the code for that is pretty much from the version you sent)
actually, do you mind if I take a look at the code for the modifications you put on so i can try fixing the fan speed?
Thanks!

[vtainc]

No problems. The code is broken, but it works :D

Here is the link: https://disk.yandex.ru/d/b3Q06C34OtcGxg

[Shuzhengz]

thanks!

[vtainc]

Okay i changed ur code a bit and it works and detects fan speed on my machine, see if it works tpfc.zip

Yes, this one works. But it seems to be, that the app always changes the fan speed to $20 and fan works at almost maximum speed in bios mode :)

[Shuzhengz]

nice
lemme add some more features and build again

[Shuzhengz]

But it seems to be, that the app always changes the fan speed to $20

hmm maybe it has something to do with the config?

[Shuzhengz]

maybe check the fan curve in smart mode

(Hey, sorry for being in the wrong place for that, but I can't help myself) I've got a Thinkbook 14 G2 Intel and can't find anything about fan control for exactly my device (which is bad, bc the fan curve is way to aggressive). I've tried plenty of software, but nothing worked so far. TPFC doesn't even shows any right temperatures. Hope you guys got some ideas :)

And sorry for the dumb question, but do I need to give access to EC somehow?

[vtainc]

No, all must be working out of the box.

[DerKatzenkoenig]

No, all must be working out of the box.

Argus works for monitoring CPU temp, but not for fan speeds (monitor and control). Your TPFC only gets "xc3" temp at 16°C and nothing else. Damn, I just want this laptop to be quiet haha

[DerKatzenkoenig]

this is what I get in tpfc. (FYI: I'm on BIOS F8CN43WW and win11 22H2 beta)

[vtainc]

hmm. strange. Seems to be, that offsets for the sensors are incorrect. See my post on the top of the thread . Download RW everything , open ec controller and search for your sensors. Then, if you can you must compile your own build using visual studio )

[vtainc]

Have you really tested all versions? :

Is it possible, that the intelligent thermal solutions driver by lenovo and vantage are disturbing tpfc?

[DerKatzenkoenig]

matter of fact: can't even launch rweverything. And yes, tested most of them. I can try to test all haha

[vtainc]

matter of fact: can't even launch rweverything. And yes, tested most of them. I can try to test all haha

Theoretically yes, they can disturb.

And yeah after win11 latest update rweverything doesn't work anymore. I think, that you must downgrade to w10 :) . I have also done this today and i'm happy :D

[DerKatzenkoenig]

Aw man. I really adapted to win11 by now :( funfact: uninstalled all power management things that I could find und got the pwr sensor haha

[DerKatzenkoenig]

byte, but fan speed can be up to 9000 rpm.

edit: nevermind, I'm giving up for now. Im hoping for some movement from lenovo (probably won't happen). It's so sad, because despite that I really like the thinkbook

can you tell me the ec controller data for cpu temp?

You must find it yourself, because I think the locations are different.

For my thinkbook 13s gen2 it is located here:

[dangothic3]

Hi,

i have the same Problem but with a Lenovo Thinkbook 15p G2 - 21B1000XGE.

The version i am using is the one of @Shuzhengz . And it now doesnt have anymore ec errors. So i think it is kind of working?!

Does anyone have an idea how to fix the problems? How do i read this rw tool?

I have windows 11

[Shuzhengz]

The one in the picture seems to be working, does manual control change the fan speed?

[dangothic3]

Sadly no. If I go to manual, it automatically switches back to smart.

Also the temperature of the cpu (1) is wrong.

[Shuzhengz]

Can you try changing the value of ManModeExit to 102 in the .ini file and try again? It might have just exited manual because it thinks the temps is too high. I'm still working on fixing the sensor issue.

[dangothic3]

Yes that worked. I can now enter the manual mode.

But i can't control anything with the maual mode. Its not the scale from 0-7 and not the one from 0 -255. Nothing happens or maybe i am just dumb...

Can I help you in any way? Do you need some more information ?

I am really thankful for your help!

[Shuzhengz]

Hi sorry, I was very busy earlier and forgot about this

Currently the release version has the address 0x2F as the data port controller address, which is in hex, and would be 47 in decimal. The number 2F means that it is on the 20 row and the 0F column, which would be this one

When using manual mode to set fan speed, the value here at 0x2F would become whatever the inputted fan speed value is (after converting to hex). But since it's not working for your system it should be in a different location.

The temperature readout is currently at address 0x78, and should be changing in real time
you can find out which address yours is by using another software to monitor your cpu temp (package temp), then convert it to hex, and find which address has the value close to it

It also turns out that on some thinkpads 0x31 seems to be the "fan selector". When the laptop starts up it hold the value 41 and with that you can control the left fan with 0x2F., and with the value 40 you can control the right fan

Hope it helps, sorry again for the late reply
