I’m using Ubuntu 24.04.3 LTS. I can see the device

However I’m seeing problems in the logs on bootup.

This would seem to be a BIOS problem? I can provide more logging if neccessary.

Please send us a picture of SN on the bottom of the PC.
We have already begun testing with relevant personnel. We will promptly notify you of any results.

Thanks, much appreciated.

Thank you for your response.
We have already consulted our R&D team regarding this issue, and it is currently being addressed.
We will provide an update as soon as we have any results.

Thankyou Bettie. Can I assume then that at least for the time being that the Mate SE Dock doesn’t work on Linux?

Hello there,

At present, we cannot give a definite answer to your question about whether Mate SE cannot work on Linux.

We will reply to you after we have the test results from the R&D personnel. Please wait patiently.

Have a nice day~

Hello there,

I have sent the lastest BIOS file for you, please check your PM.

Maybe updating BIOS can solve the problem.

Have a nice day~

Hi June, sadly things are worse now.

I flashed that new BIOS you sent in the PM successfully, and rebooted the machine back into linux which worked as usual. However it didn’t solve my problem with the Mate SE.

So, not having changed anything else (ie same devices all stayed connected), I reset the CMOS. Then, after pushing the power button it doesn’t display anything on the monitor (tested a few monitors, display port and hdmi).

I then took off all but power, monitor, keyboard and mouse. From the powered off state, pressing the power button on the front panel lights up the button and the fan is audible. However there is no further activity, and no power to the USB keyboard or mouse.

At this point pressing the power button, or holding the power button down for a prolonged period will not turn the machine off. There is nothing else I can think to do. The machine is bricked.
