power.conf檔案(在/etc 目錄中)可讓您進行系統電源的管理配置。當系統不在CDE或OpenWindows桌面的環境時,這個檔案還能讓您配置顯示器的電源。(請參閱第 2章, 監視器電源的管理 ,以獲得在那些視窗環境下管理顯示器電源的詳細資訊。)
# Power Management Configuration File # # Putting an entry in this file will only be effective if the # driver for the device supports device power management. # After the file is modified, pmconfig(1M) command must be # executed to activate the new change. # # Fields must be separated by white space or semicolons. # Note that physical dependents are automatically considered # by the power management framework. # Name Threshold(s) Logical Dependent(s) /dev/kbd 1800 /dev/mouse 1800 # NOTE: The entries below are only used when no window # system is running.

在/etc/power.conf檔案中有邏輯相依單元(Logical Dependent)的項目。 每一個項目都是一個實際裝置(像是滑鼠),而其活動和另一個裝置(像是框架緩衝器)相關,但並未實際連接在一起。
如果某個邏輯相依單元的裝置在作用中的話,那麼主要的裝置也被認為是在作用中。因此它會影響這個主要裝置的閒置時間。
