Support for the Advanced Configuration and Power Interface (ACPI) and an innovative offline-files feature make Windows 2000 Microsoft's strongest mobile-computing platform. ACPI provides greater control over power consumption, allowing you to extend your computer's battery life. (On systems without the requisite hardware for ACPI, Windows 2000 supports the older Advanced Power Management standard.)
Offline files, essentially a replacement for Briefcase in Windows NT, lets you work with local copies of network files and Web pages while you're disconnected from the network. (Briefcase is included in Windows 2000 because it's still useful under certain circumstances.) Synchronization Manager synchronizes changes made to the offline and online copies when you reconnect.
Power management is discussed in Chapter 26, "Power Management." And you can read more about using offline files and Synchronization Manager in Chapter 10, "Working Offline."
