Hope the installation procedure was helpful to you. PowerTOP is built with amazing utilities like sensors, powersave and cpu governor so each one plays its own role thus ensuring you a very low power consumption. Moreover, PowerTOP is a useful tool for laptop users as it is capable of obtaining prolonged battery life as it looks over the kernel options to estimate total power usage. Also, it is a boon for larger firms with their own servers as it reduces power consumption in a large level.
yum install powertop
run PowerTOP with the command:
powertop
# apt-get install powertop
TLP's default configuration contains all appropriate powertop recommendations and implements them automatically.
The Linux kernel has accumulated many power saving features over the years, but only a minority is enabled by default. It seems to be really hard for the kernel developers to fully debug power saving on all possible hardware, so power saving stays disabled for the majority of drivers and it's up to the user to enable it.
Conclusion: a userspace tool like TLP is still needed to enable power saving globally.
