T40 Series Service and Troubleshooting Guide

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.
