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 battery power to enter hibernation mode.
Therefore, it reserves some battery power when it is set to enter
hibernation mode at a low-battery condition. This can cause the
battery operating time to be shorter than the time shown on
page 20 and 21.
When the computer is powered with ac power and is using one
of the following IBM PC Cards, it does not enter hibernation
mode:
– IBM PCMCIA Data/FAX Modem
– IBM High Speed PCMCIA Data/FAX Modem
– IBM 3270 Emulation Credit Card Adapter
– IBM 5250 Emulation Credit Card Adapter
– IBM Token-Ring 16/4 Credit Card Adapter
– IBM Credit Card Adapter for Ethernet
This prevents possible problems from occurring with
communication application programs after the computer returns
to normal operation.
When the computer is powered with battery power, it turns
power off to the PC Card. When you resume normal operation,
if the PC Card or computer does not operate, restart the
application or computer.
