Mouse
Your mouse has one scroll wheel and two buttons: a left button and a right button. Quickly pressing and releasing
the buttons is called clicking. Sometimes, you will need to do a double-click (clicking the same button twice
quickly) or a right-click (clicking the right button quickly).
The scroll wheel in between the two buttons is added to provide easier scrolling capability. By simply moving the
wheel with your index finger, you can quickly move through multiple pages, lines, or windows. The wheel may
also function as a third button allowing you to quickly click or double-click an icon or a selected item.
For information on how to connect your mouse, please see “Connecting peripherals” on page 23.

For information on how to clean your mouse, see “To clean your pointing device” on page 3.
Note: If you are left-handed, refer to your Windows manual for instructions on how to set up your
mouse for left-handed use.
Astro.book Page 14 Friday, December 13, 2002 2:53 PM
Disk drives
Your computer comes with the following disk drives:
Diskette drive (optional)
Your computer’s 3.5-inch diskette drive accepts 720-KB and 1.44-MB capacity diskettes.
The diskettes are compact, lightweight, and easy to carry around. Here are some tips on how to take care of your
diskettes:
• Always make backup copies of the diskettes that contain important data or program files.
• Keep diskettes away from magnetic fields and sources of heat.
• To prevent data loss or damaging your files, never remove a diskette from the drive when the diskette drive
activity light is still on.
• Write-protect your diskettes to prevent accidental erasure. To do this, slide the write-protect tab to the writeprotect position.
2 System tour14
1-Write-protected
• When you put a label on a 3.5-inch diskette, make sure that the label is properly attached (flat on the surface)
and within the labeling area (area with a slight surface depression) on the diskette. An improperly attached
label may cause a diskette to get stuck in a drive when you are inserting or removing it.
2-Not Write-protected
CD-ROM/DVD-ROM/CD-RW drive (optional)
Your computer may come with a CD-ROM, DVD-ROM or a CD-RW drive. This drive is located on the front
panel of your computer. The CD-ROM drive allows you to play different types of compact discs (CDs). The DVDROM drive allows you to play not only old CD-ROMs, CD-I discs, and video CDs, but new digital video discs
(DVDs) as well. DVD or DVD-ROM is a type of disc media that holds a minimum of 4.7-GB (gigabytes), enough
for a full-length movie. It may eventually replace CD-ROMs, as well as VHS video cassettes and laser discs. The
CD-RW drive allows you to record or burn CD-RW (recordable and rewritable) discs.
CDs and DVDs, like diskettes, are also compact, lightweight, and easy to carry around. However, they are more
delicate than diskettes and must be handled with extra care.
Astro.book Page 15 Friday, December 13, 2002 2:53 PM
To insert a CD or DVD into your computer’s CD-ROM or DVD drive:
1 Gently push the Eject button located on the front panel to open the drive tray.
2 When the disc tray slides open, place the CD or DVD gently on the tray. Make sure that the label or title side
of the disc is facing upward. When holding a disc, hold it by the edges to avoid leaving smudges or
fingerprints.
15
3 Push the eject button to close the tray.
To take care of your CD or DVD discs
• Keep your disc in its case when not in use to avoid scratches or other damage. Any kind of dirt or damage can
affect the data on the disc, impair the disc lens reader on the CD or DVD drive, or stop the computer from
successfully reading the disc.
• When handling discs, always hold them by the edges to avoid smudges or fingerprints.
• When cleaning discs, use a clean, dust-free cloth and wipe in a straight line from the center to the edge. Do not
wipe in a circular motion.
• Clean your CD or DVD drive periodically. You may refer to the Cleaning kit for instructions. Cleaning kits
can be purchased in any computer or electronics shop.
Hard disk
Your computer is preinstalled with a high-capacity Enhanced-IDE (E-IDE) hard disk.
For instructions on how to upgrade or replace your hard disk, see “Replacing the hard disk” on page 43.
