That sounds more plausible than the power brick knowing about the 
temperature of the computer. You can probably check if the power 
rating of the brick matches the power consumption of the computer (it 
came with it?)


Yes - it came with it. To make it worse - the manufacturer replaced it 
and the second machine (new machine, new power brick showed the same issue)


https://www.rapidtables.com/calc/electric/Amp_to_Watt_Calculator.html

11.8 Amps at 19.5 Volts calculates to 230.1 Watts. The power supply is 
230 Watts. Unless the .1 Watts is significant or there is an error of 
some kind then they are extremely close.




A recent computer with a recent kernel should never get to the point 
where the CPU turns off because of high temperature, it should 
throttle much earlier. If that is not the case, you may check if 
automatic throttling is not disabled somewhere.


It is Ubuntu 20.04 derivative - fully updated, and the bios is also 
fully updated. Both CPU and GPU are not overloaded in terms - they never 
lock at 99% on all cores (my old machine can run on this load for many 
hours - no overheating - max goes to about 90 Celsius no power supply 
disconnect). But the new machine runs often at more than 100 Celsius (as 
a peak temperature). Normally it is within 85-95 under load but peaks 
above 100



What are the peak temperatures of your computers when under load?




Best regards,
Guillermo

Re: [darktable-user] power adapter disconnects - high temperature

[I. Ivanov]

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)?

B

In that same vein, you might turn off the power to your computer, pull 
off the bottom cover of the computer and use compressed air to blow out 
any dust accumulation.  I'm always surprised by how much dust 
accumulates in such a short period of time.

[darktable-user] power adapter disconnects - high temperature

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

utilized (like exporting thousands of images out of DT using GPU)? I 
would really want to know the temperature scope.

well, you essentially have one which you have opted to not use.  Shut dt
down after use or after an import and restart it.  Takes something less
than six seconds for dt to display on my 10 year old linux system screen.

Yes, that's it. A shortcut key to force a write would be what I am looking
