Using ACPI Power Control Under Windows 98, ACPI is a system-wide approach to system and device power control, as well as thermal management. ACPI enables the operating system to respond to events and manage power for the entire system and its devices. It makes the computer more accessible by reducing boot time and allowing the computer to wake up automatically. ACPI also incorporates power management that reduces power consumption of the computer by turning off the microprocessor and other components when applications are idle or between keystrokes. For more information on ACPI functions, consult your Microsoft Windows 98 reference guide. Using Hibernation Hibernation is a safeguard feature that saves your information when the computer reaches a low battery condition while it is left unattended. When your computer hibernates, all the information in system memory is saved to the hard disk and the power to the computer is turned off. When you turn on the computer, your information returns to the screen at the point where Hibernation initiated. Hibernation behaves like a bookmark, and none of your information is lost. When Hibernation is initiated, it creates a file on the hard drive at least equal in size to the amount of total random access memory (RAM). If there is not enough space on the hard disk to store the information, an insufficient disk space message is displayed. Hibernation will automatically initiate as long as it is not disabled (turned off) through the software. If you disable Hibernation and the computer reaches a low battery condition, your unsaved information will be lost. CAUTION: If a low battery condition occurs and you continue to use the computer, the system may not hibernate and your unsaved information will be lost. 5-6 Computer Power and Power Management Writer: Lorise Fazio Saved by: Johnnie Abercrombie Saved date: 12/08/98 4:05 PM Part Number: 310296-002 File name: Ch05.doc
