Power Management and UPS

A computer’s Basic Input/Output System (BIOS) is software through which the operating system communicates with hardware devices. Advanced Configuration and Power Interface (ACPI) is the current standard for  the way the BIOS works. Windows supports not only ACPI but also some  BIOS versions based on older Advanced Power Management (APM) designs. Some machines aren’t capable of supporting the ACPI standard, and in some the APM feature actually conflicts. Consult the HCL and be prepared to disable APM in the BIOS.
