Ramdom parts of the tlp-stat output and information from external tools are unfortunately of little help in the diagnosis.

The required kernel module may not be loaded. Please show the output of

sudo modprobe -v --first-time samsung_laptop

and

sudo tlp-stat -s -b -v

Please copy the terminal input and output here, not as a screenshot. Thank you.

running the first show :

modprobe: ERROR: could not insert 'samsung_laptop': No such device

If the kernel module does not load, you have no way to disable the threshold under Linux.

You can try an older kernel or submit a kernel bug report. Did you check if it is possible to remove the threshold in the BIOS setup?I

I can do no more for you than give you these hints.
