Solution: Apply the disk defragmentation tool in Windows for faster access to the data.

Optical drive problems

•Problem: The optical drive, such as a CD, DVD, or CD-RW drive, does not work.

Solution: Ensure that the computer is turned on and a CD, DVD, or CD-RW is properly loaded on the center pivot of the drive. (You should hear a click.)

Ensure that the drive connector is firmly connected to the computer. If you use an option that has a bay for installing the drive, ensure that the option is firmly connected to the computer and works properly.

Ensure that the drive tray is firmly closed.

Ensure that the device drivers are correctly installed.

•Problem: You hear a noise from the drive when the CD, DVD, or CD-RW is spinning.

Solution: If the disc is not properly loaded on the center pivot of the drive, it may rub against the drive cover and make a noise. Ensure that the disc is loaded properly in the drive.

•Problem: The disc tray of the optical drive does not come out at once when you press the eject button.

Solution: The empty disc tray may not come out as quickly as you expect, but the delay is normal. When no disc is in the optical drive, the drive is automatically turned off to save energy. Then, when you press the eject button, it takes a little while to turn on the optical drive and pull out the disc tray. If you need to pull out the tray immediately, press the eject button again.

•Problem: The tray does not open even if you press the eject button.

Solution: When your computer is not turned on, pressing the eject button does not cause the drive tray to open. Ensure that the computer is turned on and that the drive connector is firmly connected to the computer.

If the tray still does not open, ensure that the computer is running, and insert the end of a straightened paper clip into the emergency eject hole. The tray will open.

•Problem: An optical medium, such as a CD, a DVD, or a CD-RW, cannot be read.

Solution: Ensure that the disc is not dirty. If it is, clean it with a cleaner kit.

Test another disc. If the computer can read the other disc, the first one might be defective.

Ensure that the disc is loaded on the center pivot of the drive with the label side up. (You should hear a click.)

Ensure that the format of the disc is in one of the following formats:

–Music CD

–CD-ROM or CD-ROM XA

–Multisession photo CD

–Video CD

–DVD-ROM (DVD-video)

•Problem: The computer cannot play a CD, or the sound quality is not good.

Solution: Ensure that the disk meets the standards for your country. Usually, a disk that meets the local standards is marked with a CD logo on the label. If you use a disc that does not meet these standards, we cannot guarantee that it will play, or that, if it does play, the sound quality will be good.

A software problem

Problem: A program does not run correctly.
