Advanced Power Management
This computer supports the APM standard designed to further reduce power
consumption. APM is a power-management approach defined jointly by
Microsoft and Intel. An increasing number of software packages support
APM to take advantage of its power-saving features and allow greater system
availability without degrading performance.
For more information about APM under Windows, refer to your Windows
user’s manual.
Advanced Configuration and Power Interface
Advanced Configuration and Power Interface (ACPI) is a power-management
specification jointly developed by Intel, Microsoft, and Toshiba. ACPI enables
Windows to control the amount of power given to each device attached to the
computer. With ACPI, Windows can turn off peripheral devices when they
are not in use, thereby saving power.
