A typical computer motherboard
Internal speakers allow computers to relay audio warnings without the added complexity or cost of high-quality external speakers. Some computers have speakers installed directly on the motherboard, while others rely on small speakers connected to the case. Disconnecting internal speakers requires disassembly of the computer case for direct access to the motherboard.
Instructions
Disassemble
1. Shut down and unplug the computer.
2. Loosen the screws on the outside of the computer case.
3. Remove the computer case, being careful to disconnect any wires connecting components such as fans that may be attached to both the case and the internal components.
Disconnect
4. Locate the motherboard. This is a very large circuit board, usually aligned with the largest flat surface on the inside of the computer.
5. Locate the speaker. If it is not connected to the motherboard, it will usually be attached to an unremovable section of the computer case, such as the front near the power button. If the speaker is on-board, it will usually be small, black and round. In either case, it should be labeled "speaker."
6. Disconnect the speaker wires. Most internal speakers are connected to the motherboard by a red and a black wire. The power connector is usually a four-pin connector. Grab the connector with the pliers and pull firmly but carefully straight up from the motherboard.
