Power management Power management reduces the power consumption of certain components of the computer such as the system power supply, processor, hard disk drives, and some monitors. Automatic configuration and power interface (ACPI) BIOS Being an ACPI BIOS system, the operating system is allowed to control the power management features of the computer and the setting for Advanced Power Management (APM) BIOS mode is ignored.
Recovering software using the Rescue and Recovery program The Rescue and Recovery program provides an environment that runs independently of the Windows operating system and is hidden from the Windows operating system. Because the Rescue and Recovery workspace is hidden, it is immune from most virus attacks and provides a safe place to perform rescue and recovery operations that might not be possible in the Windows environment.
