198 If Something Goes Wrong Sound system problems Some discs run correctly but others do not. Check that the type of disc you are using is compatible with your optical disc drive. For more information regarding supported optical media formats, refer to the complete detail specifications for your computer at pcsupport.toshiba.com. If the problem is with an optical data disc, 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 optical disc drive itself. For additional information see "You press the disc eject button, but the drive tray does not slide out." on page 197. Sound system problems No sound is coming from the computer's speakers. Adjust the volume control. Try pressing Fn + Esc to see if volume mute is disabled. Check that the volume control on the computer is turned up. 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. ExpressCard® problems (Available on certain models.) ExpressCards® include many types of devices, such as a removable hard disk, additional memory, or a pager. Most ExpressCard problems occur during installation and setup of new cards. If you are having trouble getting one or more of these devices to work together, several sections in this chapter may apply. If your system does not have built-in drivers for your ExpressCard and the card did not come with an operating system driver, it may not work under the operating system. Contact the manufacturer of the ExpressCard for information about using the card under the operating system.
