If Something Goes Wrong 209 Resolving a hardware conflict CD-RW/DVD-ROM or multi-function drive problems You cannot access a disc in the drive. If the DVD-ROM or multi-function drive is an external drive, make sure that the drive’s cable is properly connected to the computer. Make sure the tray which holds the CD-ROM or DVD-ROM is closed properly. Press gently until it clicks into place. Open the tray and remove the disc. Make sure the tray is clean. Any dirt or foreign object can interfere with the laser beam. Examine the disc to see if it is dirty. If necessary, wipe it with a clean cloth dipped in water or a neutral cleaner. Replace the disc in the tray. Make sure that the disc is lying flat, label side uppermost. Close the tray carefully, making sure it has shut completely. You press the disc eject button, but the drive tray does not slide out. Make sure the computer is connected to a power source and turned on. The DVD-ROM drive eject mechanism requires power to operate. Make sure a program is not accessing the drive and preventing it from ejecting. If you need to remove a disc and cannot turn on the computer (for example, if the battery is completely discharged), use a narrow object, such as a straightened paper clip, to press the manual eject button. This button is in the small hole next to the DVD-ROM eject button on the face of the DVD-ROM tray. Never use a pencil to press the manual eject button. Pencil lead can break off inside the computer and damage it. If Something Goes Wrong 210 Resolving a hardware conflict Some discs run correctly but others do not.

If the problem is with a data CD or DVD, refer to the software’s documentation and check that the hardware configuration meets the program’s needs. The disc will not come out of the drive when you click the eject button on the screen. Press the button on the DVD-ROM drive itself. For additional information see “You press the disc eject button, but the drive tray does not slide out.” on page 209. Sound system problems You do not hear any sound from the computer. Adjust the volume control. Try pressing Fn + Esc to see if volume mute is disabled. If you are using external headphones or speakers, check that they are securely connected to your computer. The computer emits a loud, high-pitched noise. This is feedback between the microphone and the speakers. It occurs in any sound system when input from a microphone is fed to the speakers and the speaker volume is too loud. Adjust the volume control. PC Card problems PC Cards (PCMCIA-compatible) include many types of devices, such as a removable hard disk, additional memory, or a pager.
