The battery requires no charging or maintenance throughout its life; however, no
battery lasts forever. If the battery fails, the date, time, and configuration
information (including passwords) are lost. An error message is displayed when
you turn on the computer.
Refer to “Lithium Battery Notice” on page ix of this publication and Installing
Options in Your Personal Computer for information about replacing the battery.
If you replace the original lithium battery with a heavy-metal battery or a battery
with heavy-metal components, be aware of the following environmental
consideration: batteries and accumulators that contain heavy metals must not be
disposed of with normal domestic waste. They will be taken back free of charge by
the manufacturer, distributor, or representative to be recycled or disposed of in a
proper manner. For further information on battery disposal, call IBM at
1-800-IBM-4333 (1-800-426-4333) in the U.S. For information outside of the U.S.,
contact your IBM reseller or marketing representative.
Moving Your Computer
Normal shipping and handling can cause loss of data from a hard disk. If your
computer has a hard disk drive, take the following precautions:
1. Back up all files and data from the hard disk.
Operating systems can vary in the way they perform backup procedures. Some
operating systems save only data files, while others make copies of application
program files and data files. Refer to your operating system documentation for
information about software backup.
2. Remove all media (diskettes, compact discs, tapes, and so on) from the drives.
3. Turn off the computer and all attached devices. Your hard disk drive
automatically parks the read/write heads in a nondata area. This process
prevents damage to the hard disk.
4. Unplug the power cords from electrical outlets.
5. Note where you have attached your cables to the rear of the computer; then
remove them.
CAUTION:
Do not risk injury by moving or lifting the computer by yourself. Ask
another person to help you.
6. If you saved the original shipping cartons and packing materials, use them to
pack the units. If you are using different cartons, cushion the units to avoid any
damage.
