SER7: acpitz-acpi-0 temperature always 0.0°C

runic_bout_0k

I have a SER7 (bios V37) running Ubuntu 23.10 that always reports 0.0°C for the acpitz-acpi-0 sensor:

1. $ sensors
   
2. iwlwifi_1-virtual-0
   
3. Adapter: Virtual device
   
4. temp1:            N/A

7. Adapter: PCI adapter
   
8. vddgfx:        1.40 V

25. Sensor 1:     +32.9°C  (low  = -273.1°C, high = +65261.8°C)
    
26. Sensor 2:     +41.9°C  (low  = -273.1°C, high = +65261.8°C)
    
27. Sensor 8:     +32.9°C  (low  = -273.1°C, high = +65261.8°C)

I also get the following ACPI BIOS errors on boot:

1. [    0.272466] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GPP5.RTL8], AE_NOT_FOUND (20230331/dswload2-162)
   
2. [    0.272476] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20230331/psobject-220)

复制代码

Has anyone run else run into these issues with their SER7?

psg

And mine is the same.I think it's a BIOS problem.But for me the bigger problem is after BIOS V28 the ethernet Speed is limited to 100Mb/s and can't be changed.Can you post the output of "ethtool"

Hello there,
Pls try the solutions below to see if that could work.
Check sensor drivers: Ensure that all necessary sensor drivers are installed and up to date. You can use the “lmsensors” package to detect and monitor sensor readings on Ubuntu. Install it by running the following command in the terminal:

sudo apt-get install lm-sensors
After installation, run the following command to detect sensors:

sudo sensors-detect
This will scan for available sensors and prompt you to generate a configuration file. Follow the instructions provided during the process.

Verify sensor detection: Once the sensor drivers are installed and configured, run the following command to check if the acpi thermal zone is detected and the temperature readings are available:
sensors

Look for the “acpitz-acpi-0” sensor and check if the temperature readings are now being reported  correctly.

I've run sensors-detect several times and tested on Ubuntu 23.04, 23.10, and 24.04. I also used acpi-call-dkms to read "\_SB.PCI0.SBRG.EC0.DIEH" directly and got the value "0.0". All of the other fields in "\_SB.PCI0.SBRG.EC0" were also "0.0", which leads me to believe it is a firmware/BIOS issue.

1. sudo apt install acpi-call-dkms
   
2. sudo reboot 0
   
3. echo '\_SB.PCI0.SBRG.EC0.DIEH' | sudo tee /proc/acpi/call
   
4. sudo cat /proc/acpi/call
   
5. 0.0

Hello there, pls try to update this driver to see if that could work: https://mega.nz/file/fyxUhKBb#qN ... 4jL5h0R8qI0OjlZrChs . Have a nice day!

That is a Windows driver for the APU. This unfortunately is a BIOS/ACPI issue since reading "\_SB.PCI0.SBRG.EC0.DIEH" directly yields an incorrect value.

Hello, if that so, how about you try to install the other version of linux system or install windows to see if there is same issue?

I’ve tried several different linux distros, which show the same issue.

Can you or another SER7 owner post the output of running “sensors” on their device? I would like to know if this is a hardware or a BIOS issue while I am within Amazon’s return window.
