Using Power Management
Hibernation Mode
Before using hibernation mode, you must create a hibernation file.
See page 59 for instructions.
Note:
Using the Dock I, Dock II or a
particular PC Card disables
hibernation mode.
During hibernation mode, all tasks are stopped, and memory data
and the current status of the computer are stored on the hard disk
drive; then the power is turned off. When power is turned on again,
the computer automatically restores the tasks and resumes normal
operation. No battery power is used when the computer is in
hibernation mode.
Note:
The time to enter or exit hibernation
mode depends on the size of
computer memory.
It takes approximately 10 seconds to enter hibernation mode, and
18 seconds to resume normal operation (with a base memory of
8MB). When the computer is entering hibernation mode, you
receive a screen message, the computer sounds one short beep,
and the suspend indicator blinks. You also will hear one short beep
when the hibernation process is completed.
