If Something Goes Wrong Sound system problems 177 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. Printer problems This section lists some of the most common printer problems. The printer will not print. Check that the printer is connected to a working power outlet, turned on and ready (on line). Check that the printer has plenty of paper. Some printers will not start printing when there are just two or three sheets of paper left in the tray. Make sure the printer cable is firmly attached to the computer and the printer. Run the printer's self-test to check for any problem with the printer itself. Make sure you installed the proper printer drivers as shown in "Setting up a printer" on page 83 or in the instructions that came with the printer. You may have connected the printer while the computer is on. Disable Sleep mode, turn off the computer, and turn off the printer. Turn the printer back on, make sure it is online, and then turn the computer back on. Try printing another file. For example, you could create and attempt to print a short test file using Notepad. If a Notepad file prints correctly, the problem may be in your original file. If you cannot resolve the problem, contact the printer's manufacturer.
