Using Power Management Considerations for Hibernation Mode Note: The file system supported by the computer one of the following: FAT (16-bit Fat or Fat16) FAT32 HPFS The computer does not support NT File System (NTFS). Use one of the listed file systems when you make multiple partitions, and format the hard disk using the disk utility program. Consider the following before using hibernation mode: Do not run any tasks while the hibernation file is being created. Create the hibernation file only on the hard disk drive installed in the computer. The hibernation file is hidden and cannot be accessed. The computer uses the battery power to enter hibernation mode. Therefore, it reserves some battery power when it is set to enter hibernation mode when a low-battery condition occurs. This can cause the battery operating time to be shorter than the time publicly stated. Do not add or remove memory during hibernation. If you do, the computer resumes from hibernation without recognizing the changed the memory size. To ensure that the computer recognizes the correct memory size, shut down; then restart your operating system. Chapter 4. Using Battery Power 71

Using Power Management
Considerations for Hibernation Mode
Consider the following before using hibernation mode:
Do not run any tasks while the hibernation file is being created.
Note:
The file system supported by the
computer one of the following:
FAT (16—bit Fat or Fat16)
FAT32
HPFS
The computer does not support NT
File System (NTFS).
Use one of the listed file systems
when you make multiple partitions,
and format the hard disk using the
disk utility program.
Create the hibernation file only on the hard disk drive installed in
the computer.
The hibernation file is hidden and cannot be
accessed.
The computer uses the battery power to enter hibernation mode.
Therefore, it reserves some battery power when it is set to enter
hibernation mode when a low-battery condition occurs.
This can
cause the battery operating time to be shorter than the time
publicly stated.
Do not add or remove memory during hibernation.
If you do, the
computer resumes from hibernation without recognizing the
changed the memory size.
To ensure that the computer
recognizes the correct memory size, shut down; then restart
your operating system.
