I am trying to change the power profile on my ATI Mobility Radeon HD 4530 in order to prevent overheating.
I'm following instructions which say to do the following:
sudo sh -c "echo profile > /sys/class/drm/card0/device/power_method"
sudo sh -c "echo mid > /sys/class/drm/card0/device/power_profile "
However when I try and run this I get the following error
sh: 1: cannot create /sys/class/drm/card0/device/power_method: Directory nonexistent
How can I change the power profile so my laptop doesn't overheat?
