Failed to Read on Z16 Gen 1

[aricursion]

When I run the program on my Z16 Gen 1 (Windows 11) I get repeated iterations of

8/2/2022 7:03:37 PM] failed to read FanSpeedLowByte 2 from EC
[8/2/2022 7:03:37 PM] failed to read FanSpeedHighByte 2 from EC
[8/2/2022 7:03:37 PM] failed to read FanSpeedLowByte 1 from EC
[8/2/2022 7:03:37 PM] failed to read FanSpeedHighByte 1 from EC

[Shuzhengz]

does it constantly print that or does the fan control work but sometimes fail to read from EC?

[aricursion]

Apologies for not being more specific, it constantly prints that and is unable to detect the fans.

[Shuzhengz]

hm it seems like the EC address for fan speed on your laptop is different try downloading rweverything, and then open the embedded controller currently the fan status is set at 0x84, meanthing that it should be at the 80 row and 04 column in word 16 bit mode, like this:

(ignore the 05 from the 0504 as it is not important)

as in the picture the fan speed is currently at 0BD9, which is 3033 rpm in hex

because i don't have your model of laptop, it would be great if you can try and find a falue that corresponds to how your fan behaves (you can use a stress test)

also note that 0x95 (90 x 0504) has been seen as the fan speed address on thinkbooks before

Thank you!

Hi any news on this ?

[Shuzhengz]

Hi Basically I don't have the laptops to test on them, so I would actually require information from the users to fix bugs since different models of laptops might have different EC addresses (which is the case for this issue) So yeah I don't have any updates on this, sorry about that

I'm getting the same error messages on my new Thinkpad E14 Gen 4. The fan speed is located at the exact same bytes as in your screenshot. Compiling myself does not work. I was missing the tvicport.dll, after installing/providing the dll file the application does not load and is stuck throwing exceptions.

Hi

Sorry I can't manage to reproduce this, but since the exception is thrown at KernelBase.dll it probably has something to do with Visual Studio on your machine. Can you check to make sure that Desktop Development with C++ is installed with VS? Recompiling the entire project could also help

Thank you

[NeariX67]

Yes, Desktop development is the only thing i've installed, as it's needed for Flutter. Also tried to clean the project and recompile without success.

[Shuzhengz]

Can you try installinng C++/CLI support for v143 build tools, C++ MFC for latest v143 build tools and C++ ATL for latest v143 build tools packages for Visual Studio?

[NeariX67]

Still the same issue sadly

[Shuzhengz]

sadly I don't really know what might be causing this issue (seem like the program is seeking the wrong address for KernelBase, so my guess is it's a dependency issue). I have these dependencies installed, maybe check if you have the same ones as well?

sorry about that

[M0R1TZ1998]

Are there any news? I also have a Z16 Gen 1. I have ThinkPad Fan Control 0.62 installed and it reads the sensors and i can control one fan of the device, the other one not.

[GetenJoki]

Hi there, i am also having issues on my Thinkpad X13 (with two small fans). Getting the same error message as above.

Any chance of getting this fixed?
