Microsoft Corp and Advanced Micro Devices Inc have released a power management specification for network devices as part of Microsoft’s OnNow program that lets personal computers go to sleep while maintaining their network connections. The Networking Class Power Management Reference Specification, which NT 5.0 and Windows 97 will support, will enable personal computers to idle along at low power until they’re needed for network functions like peer file and printer sharing requests and systems management queries. The network OnNow spec is companion to the NT/95 Advanced Configuration and Power Interface specification released by Microsoft, Intel Corp and Toshiba America Information Systems Inc to define instant on for standalone systems (CI No 2,892).
