First of all: TYVM for your responses, time and effort, but I have to
entirely stop at this point. Reason follows down a few lines.
For the records: I did not find any DMA protection option.
While I snooped around UEFI purely out of curiosity decided to let the
integrated HW diagnostics do a quick run - with surprising results:
Battery defect, charging circuitry defective too.
Since it's not even two weeks old, I am returning this thing right
away. If I do not get my money back I will probably report back after I
get the repaired or a new device back, else I will just pick a
different laptop. Considering a Thinkpad rn...
Thanks again, TC Martin
