If you would like to upgrade the sound in your laptop computer, you will find it virtually impossible to find new internal speakers for the unit. That does not mean, however, that you cannot improve the quality of sound produced by the notebook. You can get more volume and robust sound from your laptop by simply adding a pair of external speakers.
Compare various types of external computer speakers. Look for a pair of speakers with a single cable connector. Some 5.1 channel or 7.1 channel surround sound speakers sets have more than one connector and are difficult to connect to a laptop. Therefore, a standard two-piece speaker set will be the easiest type to connect.
Establish a budget for the external speakers. A simple pair of desktop speakers usually costs less than £13 (in 2010) and provides better sound than do most integrated laptop speakers. If you want audiophile-quality sound, however, a high-end pair of external speakers can cost up to £195 or more. Most well stocked computer shops or electronics stores will have many models of computer speakers from which to choose.
Arrange the laptop and external computer speaker so that they are close together. The laptop needs to be close enough to the speakers so that you are able to connect the signal cable.
Connect the AC adaptor cable to the external speakers (if the speakers come with one). Plug the power cord for the speaker AC adaptor into an available electrical socket.
Locate your laptop computer's “Line-out” port, which is often green. In most cases, it will be on the side or the rear of the notebook. Insert the connector plug from the external speakers into the port.
Turn on the external computer speakers.
Play music CDs or launch other applications that produce sound to test the new external speakers.
