This question already has an answer here:
After tearing down my laptop, I came to know that most of the heating issue in my laptop is caused by HDD.
Powertop is also showing the same problem. I am seeing significantly cooling after activating the power saving mode using the
powertop but it is not permanent. In next
reboot it will again reset.
>Powertop output: Bad Enable SATA link power management for /dev/sda
I have already activated the
laptop-mode tool and set all the HDD power option in
laptop-mode.conf file, but non of them resolving my problem.
How can I make the
powertop suggestion permanent?
