acpi
acpi [options]
Displays information about the ACPI (Advanced Configuration and Power Interface) system, based on the /proc/acpi file. Most kernels after 2.4 support ACPI hardware, and in both hardware and software, ACPI is gradually replacing the older APM (Advanced Power Management) system. Some operating systems, including SUSE, ship a combined ACPI/APM power interface called powersaved. Most, however, require either ACPI or APM software.
Note that some ACPI systems have special events that are not available on others. For example, IBM laptops have events related to their docking stations and keyboard lights that are not used on nondocking or unlighted laptops. On all systems, the /proc/acpi directory must be present for acpi commands to work.
