I installed elementary OS on my HP notebook with an AMD A8. My notebook is heating up and the cooler is fired all the time. What can I do to improve it?
Try upgrading to kernel 4.4 by running
cd /tmp
wget \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.6-wily/linux-headers-4.4.6-040406_4.4.6-040406.201603161231_all.deb \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.6-wily/linux-headers-4.4.6-040406-generic_4.4.6-040406.201603161231_i386.deb \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.6-wily/linux-image-4.4.6-040406-generic_4.4.6-040406.201603161231_i386.deb
sudo dpkg -i linux-headers-4.4*.deb linux-image-4.4*.deb
This will upgrade the kernel to 4.4. Now reboot so you get the new kernel
Then install TLP by running
sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo tlp start
sudo apt-get install thermald
You may get a black screen on boot sometimes but can be fixed by closing the lid and opening it again
You can also use the power button (press once , do not hold down) to put it to sleep and turn it on again.
sudo apt-get install xsensorsin terminal and the open Xsensors from applications. Add your CPU temperature to the answer
