What is ACPI?? Is it important? My sound blaster emulator IRQ is conflicting with the ACPI, should I just disable ACPI? Please help me!!
 
Microsoft Windows 2000 provides three levels of power-management support. On computers that are fully compliant with the Advanced Configuration and Power Interface (ACPI) specification, the operating system maintains efficient and reliable control of the power supplied to your monitor, disk drives, peripherals and motherboard components, reducing power to those components appropiately when your computer is inactive. On many systems that are not ACPI compliant but that use an Advanced Power Management (APM) 1.2 BIOS, Windows can provide a serviceable, if somewhat less versatile, form of power management. And on some earlier systems that do not have an APM 1.2 BIOS, the operating system can still conserve power by having the opertating system shut down the monitor and disk drives during periods of inactivity.

The advantage of ACPI over APM is that ACPI puts power management completely in the control of the operating system. Because ACPI is an operating-system specification, Windows 2000 can provide a consistent approach to power management across all ACPI-compliant systems, thereby ensuring reliability while reducing training costs and user perplexity. With applications that are designed for ACPI, an ACPI-compliant system can also track the status of running or scheduled programs and coordinate power transitions with applications as well as hardware.

Over advantages of ACPI include:

Control of USB and FireWire devices.
Support for wake-on-LAN and wake-on-ring.
User definition of the power and reset buttons.
Better battery management.
Dynamic configuration of PC cards.
Server and multiprocessor support.

Bit of information overload there. But you get the jist. Disable it by all means if it solves the problem.
