Maintenance 1

Maintenance

This section includes information about tasks you can perform to help ensure the trouble-

free operation of your computer, and to ease the recovery of important information on

your computer should problems arise in the future.

Creating Data Backup Discs

You can use the CD or DVD burning software included on your computer to create backup

discs of important information including personal files, e-mail messages, and Web site

bookmarks.

When writing data to a backup disc, you should use software that includes write

verification functionality. This verification feature compares the data on your hard disk

drive with the data copied to the disc to ensure it is an exact copy. Depending on your disc

burning software, you may need to manually enable this feature.

Creating System Recovery Discs

This is a one-time step that you should perform while your computer is working properly. If

you later encounter problems with your computer, you can restore it to its original factory

settings using the System Recovery discs that you create.

Before creating recovery discs, read “System Recovery” on page 25, and then create the

discs as described in “Creating Recovery Discs” on page 25.

Removing Unused Programs

1Click the Windows Start Button®, and then click Control Panel.

2Click Uninstall a program. The Programs and Features window opens.

3Select the program you want to remove, and click Uninstall.

4Follow the onscreen instructions.

NOTE: Some programs have their own uninstall features. If you cannot uninstall a

program from the Control Panel, refer to the program documentation or Help.

2Troubleshooting and Maintenance Guide

Running the Disk Cleanup Program

The Disk Cleanup program frees up space on your hard disk drive by removing temporary

and unused files (including Temporary Internet Files and files in the Recycle Bin). You can

run Disk Cleanup manually, or you can set it up to run automatically.

Running Disk Cleanup manually

1Click the Windows Start Button, All Programs, Accessories, System Tools,

and then click Disk Cleanup.

Disk Cleanup searches for files to delete and calculates how much disk space can be

saved.

2Choose the files to delete by placing a check mark in the check box next to the file

types listed.

3Click OK, and then click Delete Files to finish deleting the selected files.

Scheduling Disk Cleanup to run automatically

1Click the Windows Start Button, All Programs, Accessories, System Tools,

and then click Task Scheduler.

2Click Action, and then click Create Basic Task.

3Type a name for the task and an optional description, and then click Next.

4Select the reoccurrence, and click Next.

5Select the time to run Disk Cleanup and click Next. Disk Cleanup may take a long

time, so select a time when the computer is on but not in use.

6Select Start a program and click Next.

7Under Program/Script, click Browse.

8Type cleanmgr.exe and click Open.

9Review the summary of the schedule you have set. When done, click Finish.

Disk Cleanup runs at the time you have set.

Maintenance 3

Running the Disk Defragmenter Program

When Microsoft® Windows Vista™ stores files on your hard disk drive, it often divides

them into multiple pieces (or fragments) so they fit into available space on the drive. When

you attempt to open a fragmented file, it must be retrieved from more than one place, so

the process takes more time.

The Disk Defragmenter program groups the fragmented files together on your hard disk

drive to improve computer performance. This does not affect the location of files and

folders on your computer.

1Save your work and close all open programs.

2Press the Ctrl key, the Alt key, and the Delete key at the same time.

3Click Start Task Manager.

4On the Applications tab, select all the programs that are listed, and then click

End Task. Close the Task Manager.

5Click the Windows Start Button, choose All Programs, Accessories,System

Tools, and then click Disk Defragmenter.

6Click Defragment Now.

If Disk Defragmenter repeatedly starts, a hidden background program is still accessing the

hard disk drive. Restart the computer and run the Disk Defragmenter program again:

1Click the Windows Start Button, click the arrow next to the

Lock button, and then click Restart.

2After Windows Vista starts, use the previous procedure to run the

Disk Defragmenter program.

NOTE: The Disk Defragmenter program may take a long time to complete. You can run it

unattended overnight.

4Troubleshooting and Maintenance Guide

Checking for Hard Disk Drive Errors

Perform the following procedure to check the integrity of the hard disk drive in Windows

Vista. Close all open programs before beginning the disk check.

1Click the Windows Start Button, and then click Computer.

2In the window that opens, right-click the hard disk drive that you want to check, and

click Properties.

3In the Properties window, click the Tools tab.

4Under Error-checking, click Check Now.

5If desired, click the check box next to Automatically fix file system errors and

Scan for and attempt recovery of bad sectors.

6Click Start. If prompted to restart, click Yes to restart the computer.

Understanding Hard Disk Drive Space

Hewlett-Packard and Compaq computers with the Windows Vista operating system

preinstalled may appear to have a hard disk drive smaller than what is stated in the

product specifications, in the documentation, or on the box. Hard disk drives are

described and advertised by manufacturers in terms of decimal (base 10) capacity.

Windows Vista and other programs, such as FDISK, use the binary (base 2) numbering

system.

In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, and one gigabyte

(GB) is equal to 1,000,000,000 bytes. In the binary numbering system, one megabyte is

equal to 1,048,576 bytes, and one gigabyte is equal to 1,073,741,824 bytes. Because

of the different measuring systems, you may see a difference between the size reported by

Windows Vista and the size advertised. The storage capacity of the hard disk drive is as

advertised.

Windows Vista reports smaller capacity in the Windows Explorer tool and in the Computer

window because it shows information about one partition on the hard disk drive at a time.

The first partition contains the System Recovery information.
