HwInfo not reporting Nvidia's "GPU Rail Powers" and "GPU Core (NVVDD) Output Power" if set to auto startup

[ArcherLegend]

I have HwInfo configured to auto start the sensor monitoring at startup however what happens on my laptop is that the dGPU (an Nvidia MX230) is picked up correctly but the 2 values indicated in the title are not measured and they do not appear when the GPU is being used by a program neither.
This bug occurs only when HwInfo auto starts because the sensors are correctly picked up if HwInfo is started manually, I have also tried to postpone the auto start to 1 or 2 minutes after the boot however the bug is still present.

The wake disabled GPUs and Poll Sleeping GPUs settings are ticked but do not seem to affect this bug which is present with both options either on or off or a combination of the 2.

Please attach two HWiNFO Debug Files - one of when HWiNFO is automatically started and another one when manually so I can analyze the difference.

I have attached the debug fles now.

Looks like the problem here is that NVIDIA's drivers act different for applications started with Windows and doesn't provide certain information here.
You might rather try to use a different startup method than the Auto Start (which creates a task in Task Scheduler), for example create a HWiNFO shortcut in the Startup folder in Start Menu.

Thank you for looking into it.

I have worked on the issue a little bit and I have found an interesting thing.

I have DDUed all the drivers and I have clean installed them.

I have found that the cause may not be the Nvidia driver but possibly a driver conflict (?).
If the Intel UHD 620 iGPU driver is version 27.20.100.8681 the sensor is picked up correctly by HwInfo whereas if I use the latest Intel driver which is 31.0.101.2125 the power sensor of my MX230 is not picked up anymore upon an automatic startup and requires a manual start of HwInfo.

Furthermore I have discovered that if while HwInfo is autostarting if I manage to open an application which activates the Nvidia dGPU the sensor is picked up correctly regardless of the Intel driver version.

I am opening a bug report with Intel even though I don't think they'll understand what the problem is and I am leaving what I have found here in case someone has my same "issue".

Interesting, thanks for sharing the information.
I'm not sure if this is a real bug, probably the dGPU is being put into a deeper sleep state which isn't picked up by HWiNFO once it wakes up.
This might be possible to workaround in HWiNFO, I will try to fix it in the next (Beta) build.

Ok I'll keep my eyes opened for that, meanwhile I have opened a ticket with Intel (even though I think that even if the agent understands the problem the issue won't be looked into as they have more important stuff to do on Arc rather than work a small bug which no one noticed).

This should be fixed in version 7.65-5245 Beta, please try and let me know.

 

[ArcherLegend]

I can confirm that you fixed the issue, thank you.
If I can ask, what was causing the bug?

 

[Martin]

Thanks for the feedback.
It was because certain queries that were checked only at HWiNFO startup previously worked also when the GPU was disabled, but now they work only once the GPU is online.
