My netbook gets hot when I plug the AC adapter.

Re: My netbook gets hot when I plug the AC adapter.

It's not strange. Jupiter has a bunch of scripts and daemons, one of which enables the performance CPU frequency scaling governor when on AC. Higher CPU frequency clock = higher temps. What you can do is click on the applet and select the middle mode (not powersave and not maximum performance, I think it's called high performance). This will enable the onedemand freq governor, and cool down your system. You can also look at all the scripts (/etc/init.d/jupiter or something), and edit the file which associates the Maximum performance mode with the performance governor.

Re: My netbook gets hot when I plug the AC adapter.

I'm trying it, but I have bad news. I selected the High performance mode. And I'm having the same results. Well I have to say that now I haven't reached 60º when I launch the Web Browser, although it stays at 54º without doing anything (58º with the web browser).

Thanks for the answer.

PS: Before I had the Jupiter applet in Powersave mode although I had the AC connected.

Re: My netbook gets hot when I plug the AC adapter.

Open a terminal and run `sensors`.  Take a look at the critical temperature for your CPU.  You'll feel a whole lot better about the 60°+ reading. wink

Re: My netbook gets hot when I plug the AC adapter.

Uninstall cpufreqd, and install cpufrequtils if it isn't already installed. Plus, post the output of

locate jupiter

Paste the outputs of

Re: My netbook gets hot when I plug the AC adapter.

In /usr/lib/jupiter/scripts/cpu-control edit

if [ "$FSBTARGET" = "super" ]; then
    RMODE="Maximum Performance"
    CPUMODE="performance"
    NICON="/usr/share/pixmaps/jupiter/bolt2.png"
  fi

To this:

if [ "$FSBTARGET" = "super" ]; then
    RMODE="Maximum Performance"
    CPUMODE="ondemand"
    NICON="/usr/share/pixmaps/jupiter/bolt2.png"
  fi

And reboot. Other otpions are "powersave" and "conservative". One of those frequency scaling modes will cool down your laptop to your liking. When you're on battery, the system is using the powersave governor.

Re: My netbook gets hot when I plug the AC adapter.

I've been trying, and I have bad news. I'm obtaining the same results. When I was writing the post above, my computer was about 46º, (I wrote that using only the battery), more or less, but now it's over 56º.

What else can I do?.

Thank you very much for your answers and help.

EDIT: I've been thinking. When I only use the battery, I don't know how to say, but may be de HDD reduces its velocity or something?. I can feel the netbook noisier when I use the AC adapter. I don't know if this could mean anything.

Re: My netbook gets hot when I plug the AC adapter.

Ahhh, I forgot about that. Try to run:

sudo hdparm -B254 /dev/sda

when you plug the power in. If it reduces the heat, we'll set it up permanently.

Plus, do you even have cpufrequtils installed?

apt-cache policy cpufrequtils

Re: My netbook gets hot when I plug the AC adapter.

Plug in the AC and do

sudo cpufreq-set -g powersave

Run it for a while and give me the results.

Re: My netbook gets hot when I plug the AC adapter.

Depending on your mobo and chipset, 90+ may be pushing it.  What does sensors report for your CPU's critical temp?

Re: My netbook gets hot when I plug the AC adapter.

Netbooks shouldn't run so hot. As you can see, the OP has only started reporting problems after installing Jupiter. I had the same problem, so I removed Jupiter, as battery life is of little consequence for me. Machines with AMD chipsets run hotter in general, Atoms with intel graphics should be pretty cool. #! by default comes without cpufrequtils, which usually lowers temps significantly. Asus's IceCool (TM) technology is pretty nice though.
