Using Power Management
Hibernation Mode
Notes:
1. Before using hibernation mode,
you must create a hibernation
file.
2. Using a particular PC Card can
disable the hibernation mode.
(See page 76.)
3. With a base memory of 8MB, it
takes approximately 10 seconds
to enter hibernation mode and 18
seconds to resume normal
operation. (The time to enter or
exit hibernation mode depends
on the computer memory size.)
In hibernation mode, all tasks are stopped and memory data and the
current status of the computer are stored on the hard disk drive;
then power is turned off. No battery power is used. When power is
turned on again, the computer automatically restores the tasks and
resumes normal operation. When the computer enters hibernation
mode, you hear one short beep. A graphical message appears and
the suspend mode indicator lamp blinks; then a short beep sounds
again to inform you that the computer has entered hibernation mode.
Creating the Hibernation File
Attention:
The hibernation file must not be
created in a compressed data area
of the hard disk.
When installing an operating system or installing additional computer
memory, you must create a hibernation file on the hard disk drive to
use the hibernation mode. (You need to create the hibernation file
only once after installing an operating system or additional memory.)
The size of the hibernation file will be approximately 1MB greater
than total memory. For example, if you have installed an optional
16MB memory module (DIMM) and since the base memory is 8MB,
the hibernation file is 25MB:
(16MB + 8MB) + 1MB = 25MB
The following describes how to create a hibernation file for your
operating system.
