acpi:tldr:90858

The command acpi -V is used to display detailed information about a computer's battery and ACPI (Advanced Configuration and Power Interface) settings.

ACPI is a standard for interfacing with hardware components and power management functionality in modern computers. It allows software to monitor and control various aspects of a system's power resources.

The -V option with the acpi command stands for "verbose," which means it provides more detailed information. When you run acpi -V in the terminal, it will typically display information such as the battery's current state of charge, capacity, estimated time remaining, and temperature. It may also show information related to other ACPI devices and hardware components, such as thermal zones or fans.

This command is useful for checking the status of your battery, monitoring power usage, and troubleshooting power-related issues on a Linux system.
