Thank you All!
It is really odd. It is a brand new laptop and I can reproduce the issue
consistently. But it does appear to be related to heath. The computer is
on a flat surface (table) and nothing blocking vents around. Normal
ambient temperature 26 Celsius.
I am really puzzled how the power supply knows or reacts. It is just a
power brick. So - no information flowing from the laptop to the power
supply (how hot it is - the laptop). Do you think the power supply does
not match the laptop correctly so the power drawn when all CPU, GPU and
file copy overburden it and in turns it cuts the power (because itself
it becomes too hot too)?

Normally that would never happen, but maybe your new laptop pushed the
envelope a little on a hot day...

Hi All,
I know it is quite a stretch but .... have anybody heard of a
possibility of a power adapter cutting the power to the laptop on
its own?
I am observing a very strange issue on a linux laptop and I can only
simulate it for now when DT is used - using GPU - new AMD processor,
exporting thousands of images then - when the temperature rises -
start
intense disk operations (copying of files for example). Unplug the
power
adapter from the wall is needed to restore the power.
If anybody is using AMD based linux laptop - would you mind please
sending a screenshot from "Psensor" when the computer is heavily
utilized (like exporting thousands of images out of DT using GPU)? I
would really want to know the temperature scope.
The ones of main concern for me are "Tdie" "Tctl" "temp1" (the 4th
value
top to bottom on Psensor)
Have anybody seen more than 100 Celsius on the above values on any
laptop when under stress? If not - what do you observe as a normal
scope
for you when the machine is under stress?
Thank you in advance!
