Troubleshooting

If the Notebook Cannot Read a CD or DVD

■For a single-sided CD or DVD, make sure the disc is placed in the drive with the label facing up.

■Clean the disc.

■Wait 5 to 10 seconds after closing the tray to give the notebook time to recognize the disc.

■Restart the system: remove the disc from the drive, and select Start > Turn Off Computer > Restart.

■If you created the CD on a DVD/CDRW combo-type drive, try using a different media brand. Read and write quality may vary for media.

If a DVD Movie Does Not Fill the Screen

Each side of a double-sided DVD has a different format (standard or widescreen). In widescreen format, black bands appear at the top and bottom of the screen. To view the standard format, flip the disc over and play the other side.

Display Problems

If the Notebook Is On, But the Screen Is Blank

If the Screen Is Difficult to Read

■Adjust the size of the desktop icons and labels.

■Adjust the brightness of the screen.
