Lighten KDE

Postby palimmo » 16 Mar 2018 07:08

Hi.
Sometimes my laptop becomes too hot and it switches off suddenly by itself.
It happens when I watch videos on Firefox (ESR).
I have SolydK 964bit and my laptop is ca. 9 year old. However it is still pretty good for what I need.

I think I still could reduce the usage of CPU and RAM in order to avoid this problem. What would you suggest?
For example: How could I remove Discover from the Autostart Services? I do not really need it.
Any other suggestions?

Thanks

There are a couple or three things I would look at:
  • First I would ensure that all vents and cooling solutions are free of dust. No matter how careful I am, I'm always amazed at how quickly vents get blocked.
  • How about the thermal grease between your CPU and its cooling solution? And between the graphics chip and its cooler? I've ready/heard that, as the thermal grease gets older and more dried out, it becomes less thermally efficient. I just took apart a computer I built about five years ago and was amazed at the condition of the grease. I replaced the greast as part of putting it back together and now I'm amazed at how much cooler it runs.
  • How about running

    Code: Select all

    systemd-analyze blame
    to get a list of processes that start up when the computer boots? These might be a target list of something that could be disabled.
  • How about running something like "top" to get a list of running processes that are currently consuming CPU resources? There might be something there.
Of course, I'm sure there are some here (myself included) who would be interested in some hardware details. Running "inxi -Fzxx" (and posting back here the results of) might be a good way to get some helpful discussion started.

cleaning and putting new thermal grease is a good start. in my experience, honestly, you can't do much to decrease the system load. even if you disable some service, when you start the browser it will eat all the resources. I usually goes with limiting either gpu/cpu performance. you can use tools like tlp to do that. another viable option would be using firefox quantum instead of esr. the esr is using old technogy and known as resource eater. the quantum is said using less resource compared to esr one.

btw, I see that you have nvidia. do you have hybrid gpu? if that true, IIRC nvidia has special driver for hybrid gpu which will manage the GPU based on system demand. most of overheating issue on hybrids are because both intel and nvidia run at the same time. I think it was called optimus

Yes, and SolydXK System Settings can help you install the proper drivers. It should list your card in the first tab.

I renew the thermal paste on the CPU and on the GPU.
Let see if it goes better in the next days.

If done correctly - that is with as thin a layer of grease possible - I don't see how this can have anything but positive results.

BTW and FWIW - when I do this (and I've never had anything but positive results) is to apply a little bit too much grease to one of the surfaces and then scrap most of it off with a single-edged razor blade - squeege-fashion. This gets the grease covering ALL the mating surface between the cooling solution and the CPU and reduces the thickness of the grease to the recommended "paper-thin" application.

Anyway - here's hoping you get the results you're looking for!

You might consider using SolydX - not as fancy as SolydK is but a lot lighter on ressources. Although heating problems should be fixed the way scott told you. Here's a video: https://www.youtube.com/watch?v=cFclhLPET4U&vl=de which might fir your model.
Just beware that opening up a laptop is not for the faint of heart - I know cause I just did it. :geek:
What looks so easy on youtube is not that easy in reality - try to have 4 hands at the ready and be prepared to use some force. I ended up with a broken connector which I had to re-solder :ugeek: not possible without special equipment (hot air soldering with microscope :ugeek: :ugeek: ).
