Maintenance 1
Maintenance
This section includes information about tasks you can perform to help ensure the troublefree 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
1 Click the Windows Start Button®, and then click Control Panel.
2 Click Uninstall a program. The Programs and Features window opens.
3 Select the program you want to remove, and click Uninstall.
4 Follow 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.
2 Troubleshooting 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
1 Click 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.
2 Choose the files to delete by placing a check mark in the check box next to the file
types listed.
3 Click OK, and then click Delete Files to finish deleting the selected files.
Scheduling Disk Cleanup to run automatically
1 Click the Windows Start Button, All Programs, Accessories, System Tools,
and then click Task Scheduler.
2 Click Action, and then click Create Basic Task.
3 Type a name for the task and an optional description, and then click Next.
4 Select the reoccurrence, and click Next.
5 Select 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.
6 Select Start a program and click Next.
7 Under Program/Script, click Browse.
8 Type cleanmgr.exe and click Open.
9 Review 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.
1 Save your work and close all open programs.
2 Press the Ctrl key, the Alt key, and the Delete key at the same time.
3 Click Start Task Manager.
4 On the Applications tab, select all the programs that are listed, and then click
End Task. Close the Task Manager.
5 Click the Windows Start Button, choose All Programs, Accessories, System
Tools, and then click Disk Defragmenter.
6 Click 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:
1 Click the Windows Start Button, click the arrow next to the
Lock button, and then click Restart.
2 After 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.
4 Troubleshooting 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.
1 Click the Windows Start Button, and then click Computer.
2 In the window that opens, right-click the hard disk drive that you want to check, and
click Properties.
3 In the Properties window, click the Tools tab.
4 Under Error-checking, click Check Now.
5 If desired, click the check box next to Automatically fix file system errors and
Scan for and attempt recovery of bad sectors.
6 Click 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.
