Hardware
This entry focusses on various hardware components of a desktop PC or a laptop.
Battery
The battery of a notebook can be inspected by using the upower command.
To use it the tool needs to be installed.
In most Linux distributions this is bundled in a package of the same name.
A usage example is shown in the following command.
It will show the state, voltage, percentage and many other information about a given battery.
upower -i /org/freedesktop/UPower/devices/battery_BAT0
Alternatively acpi can be used to achieve the same.
For this run the following command.
acpi -b
Power Management
Tools, programs and guides to manage the power usage and improve battery life are described in the power management entry.
(Liquid) Coolers
The viewing of temperatures of coolers aswell as the selection of RGB-settings can be achieved by using liquidctl.
Temperature
To check the temperature the command sensors can be used which (on most distributions) is a part
of the lm_sensors package.
It will then display all the available temperature sensors available aswell as many other sensors
like the RPM for fans.
