linux acpi: Show all information



2 min read

Linux ACPI is a powerful tool that allows users to access and monitor various hardware information on their systems. By leveraging the ACPI (Advanced Configuration and Power Interface) framework, Linux can gather data such as battery status, temperature, and fan speeds. In this article, we will dive into how to show all available information using Linux ACPI.

To retrieve ACPI information, we can use the acpi command-line utility. This command provides a straightforward way to get detailed hardware information directly from the kernel. Let's take a look at an example:

acpi -V

This command will display a comprehensive list of information, including battery status, thermal zone readings, and power adapter details. The output will vary depending on your system and the available ACPI data.

To view battery information specifically, we can use the following command:

acpi -b

This will show details such as the battery's capacity, remaining charge, and current status (charging, discharging, or fully charged). It's essential to keep an eye on battery health, especially for laptop users who rely heavily on their devices.

Temperature monitoring is also a crucial aspect of system maintenance. To check the thermal zone temperatures, you can run the following command:

acpi -t

This will give you the current temperature readings for each available thermal zone. Monitoring these temperatures can help identify potential issues with cooling or excessive heat.

Additionally, if you want to examine the status of your power adapter, the following command will provide detailed information:

acpi -a

This command will tell you if your system is connected to an AC power source or running on battery.

By utilizing the Linux ACPI framework and the acpi command-line utility, you can efficiently retrieve vital hardware information on your system. Whether you need to monitor battery health, keep an eye on temperature levels, or check power source details, Linux ACPI has got you covered.

Remember to consult your system's documentation or online resources for additional options and flags that can further enhance the functionality of the acpi command.
