Information about hard disk capacity
Instead of providing a recovery CD or a Windows
®
CD with your computer, IBM
®
provides simpler
methods of accomplishing the tasks typically associated with these CDs. The files and programs for
these alternative methods are on your hard disk, which eliminates having to locate misplaced CDs and
problems associated with using an incorrect CD version.
The complete backup of all the files and programs that IBM preinstalled on your computer resides in a
hidden section, or partition, of the hard disk. Although hidden, the backups in the partition consume
hard disk space. Therefore, when checking the capacity of your hard disk according to Windows, you
might note that the total capacity of the disk appears to be smaller than anticipated. This discrepancy is
explained by the contents of the hidden partition.
For more information about recovering your hard disk to the original preinstalled contents refer to your
on-system help source, Access IBM. Press the blue Access IBM button or click the Access IBM icon on
your desktop, and then browse the Learn section for various topics that cover backing up and
recovering.

Finding information with Access IBM
The blue Access IBM button can help you in many situations when your
computer is working normally; and even when it is not. At your desktop,
press the Access IBM button to open Access IBM. Access IBM is your
on-board computer help center that brings you informative illustrations and
easy-to-follow instructions for getting started and staying productive. You can
also use the Access IBM button to interrupt the startup sequence of your
computer and start the Access IBM Predesktop Area. If Windows does not
start correctly, press the Access IBM button during the startup sequence of
your computer and start the Access IBM Predesktop Area. Use this area to run
diagnostics, restore your backups (assuming you have made backups using
IBM Rapid Restore PC), restore to factory contents (ie, what was there when
you received your computer), start a utility that enables you to change your
startup sequence, and get essential system information, and start the IBM
BIOS Setup Utility where you can check and change BIOS settings. Press the
Access IBM button to open the application that brings all of IBM’s resources
to you. On the next page, you will see the Welcome page of Access IBM that

explains what each part of Access IBM holds to help you.
Some of the topics in your help system contain brief video clips that show
you how to perform certain tasks, such as replacing your battery, inserting a
PC Card, or upgrading your memory. Use the controls shown to play, pause,
and rewind the video clip.
