Considerations for Hibernation Mode Consider the following before using hibernation mode: Do not run any other tasks while the hibernation file is being created. The computer uses battery power to enter hibernation mode. Therefore, it reserves some battery power if 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 mode. If you do, the computer resumes from hibernation mode without recognizing the changed memory size. To ensure that the computer recognizes the correct memory size, shut down; then restart your operating system. If the computer is powered with battery power, it turns power off to the PC Card when entering hibernation mode. When normal operation resumes, if the PC Card or computer does not operate, restart the application or computer. If you are using some communication cards and your computer is powered with ac power, the computer does not enter hibernation mode. This prevents possible problems from occurring with communication application programs after the computer returns to normal operation. Note: If the communication links are still not reestablished, remove and then reinstall the PC Card before restarting the system or application program. Notes for Reinstalling or Installing the Operating System Install your operating system with Advanced Power Management (APM), and install the ThinkPad Configuration program with the Utility Diskette to use power management mode. Note: To install the software Installing a New Operating System and Its Device Drivers . If you are using Windows 95 or OS/2, APM is automatically installed in your computer. Chapter 4.

Considerations for Hibernation Mode
Consider the following before using hibernation mode:
Do not run any other tasks while the hibernation file is being
created.
The computer uses battery power to enter hibernation mode.
Therefore, it reserves some battery power if 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 mode.
If you
do, the computer resumes from hibernation mode without
recognizing the changed memory size.
To ensure that the
computer recognizes the correct memory size, shut down; then
restart your operating system.
If the computer is powered with battery power, it turns power off
to the PC Card when entering hibernation mode.
When normal
operation resumes, if the PC Card or computer does not operate,
restart the application or computer.
If you are using some communication cards and your computer
is powered with ac power, the computer does not enter
hibernation mode.
This prevents possible problems from
occurring with communication application programs after the
computer returns to normal operation.
Note:
If the communication links are still not reestablished,
remove and then reinstall the PC Card before restarting
the system or application program.
Notes for Reinstalling or Installing the Operating System
Install your operating system with Advanced Power Management
(APM), and install the ThinkPad Configuration program with the
Utility Diskette to use power management mode.
Note:
To install the software
Installing a New Operating System
and Its Device Drivers .
If you are using Windows 95 or OS/2,
APM is automatically
installed in your computer.
