laptop going to sleep even plugged

I have an Acer Aspire E1-771G. I sometimes launch long computations like a rendering in Flowblade. Problem is, after a while (maybe 30mn) my computer goes to sleep and it seems to terminate the computation process (the rendering file is truncated).
I set "Put to sleep : never" in plugged mode in the Xfce power manager, which is what I would like (never go to sleep) but the computer still falls asleep. I haven't found anything corresponding to this situation in the forums. What should I do ?

Re: laptop going to sleep even plugged

Does it actually go to sleep (suspend the OS) or does it just turn of the display? Do you run your computing loads on the GPU or the CPU, and if it doesn't suspend wholly, could you confirm that CPU-bound tasks run and complete just fine while GPU-bound tasks are interrupted?

Interesting, I hadn't thought of the GPU. I don't know if Flowblade makes use of it. I tried to monitor the GPU activity in Conky but no "nvidia" option works (result is "N/A").

I don't know if only the display turns off.

I usually let my laptop go asleep (whatever kind) with programs running and they don't abort. That's been only since i generated big files with Flowblade (possibly involving GPU, so).

I confess I lack a few notions to answer your questions !
