ACPI is not power management. It's a set of infrastructure (including an interpreter and small firmware programs to drive specialized hardware) that allows the important details of your motherboard to be described accurately to the kernel by firmware authors. That's why it's called "Advanced Configuration and Power Interface" and not just "Advanced Power Interface" :-) It also provides more accurate tables to describe things like the cpus in your system etc., to replace deprecated mechanisms for that such as MPS.
