The best way to determine which, if either, your system supports is to build a kernel with both ACPI and APM enabled (as of 2.3.x ACPI is enabled by default). If a working ACPI implementation is found, the ACPI driver will override and disable APM, otherwise the APM driver will be used.

You need a kernel that has the APM driver compiled in using the appropriate kernel configuration options. Currently most distributions do not ship kernels with the APM driver enabled so you may have to enable the driver using a boot option or to compile a custom kernel.

Advanced power management is an API developed by Intel and Microsoft and released in 1992 which enables an operating system running an IBM-compatible personal computer to work with the BIOS to achieve power management. Revision 1.2 was the last version of the APM specification, released in 1996. ACPI is intended as the successor to APM. Microsoft dropped support for APM in Windows Vista. The Linux kernel still mostly supports APM…
