Three suggestions:
1. Make sure you are using the proprietary video drivers. They are generally better at managing heat.
2. You could also try booting with the acpi_osi="Linux" kernel parameter (see: https://help.ubuntu.com/community/Gr...nu During Boot for instructions on how to temporarily test it. Haven't had much success with this one lately though.
3. You could change the cpu governor. To see what cpu frequencies your laptop supports, open a terminal window and type in the following:
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
And to see what governors your laptop supports, type in the following:
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
Here is a brief description of what the governors mean:
ondemand - when the demand on the cpu increases, ubuntu changes the cpu frequency immediately to its highest supported level and remains there will the demand exists. When the demand ends, it drops to its lowest level. This is the ubuntu default.
conservative - this is like ondemand, except that it slowly increases and decreases through the available frequencies as demand requires.
performance - this runs the cpu at the highest frequency all of the time
powersave - this runs the cpu at the lowest frequency all of the time
userspace - this allows another program to manage cpu frequencies
Like I said, ondemand is the ubuntu default. You could try the other governors to see if it makes a difference.
To change the governor, edit the ondemand init file:
Code:
gksudo gedit /etc/init.d/ondemand
...and replace the line:
echo -n ondemand > $CPUFREQ
...with the governor you want to use. (e.g.):
Code:
echo -n conservative > $CPUFREQ
Then restart.
You might want to give conservative and powersave a shot.
