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
Please anyone suggest any solution to this problem?
How can I make the Powertop suggestion permanent.
