Is the external speaker system working? When you turn it on, be it connected to the computer or not, is there a pilot lamp that indicates that it is powering up? Can you hear any noises from the speakers when you turn the unit on? If so, or even if not so, do the following: Ensure that the speaker that does not contain the off/on and volume knobs is connected to the speaker that houses those controls. Now, with the unit ostensibly turned on, increase the volume control at least half way to full volume. Touch your finger to the tip of the plug that inserts into the audio output jack of your computer. You should now hear a hum or buzz from one of your speakers. If not, your external speaker system is probably not functioning and it is likely a fault in the amplifier section, power supply (if the unit is not powering up) or a broken audio cable. Otherwise, there is some issue internal to your computer.
