Laptop computers are typically equipped with a pair of small, built-in stereo speakers that produce a modest sound. The headphone jack on the edge of most laptops can also be used to connect a pair of external speakers to pump up the volume and provide greater audio fidelity when listening to music, enjoying multimedia content or gaming. The speakers must be self-powered because the amplifier in the laptop is only powerful enough to drive the small built-in speakers. A pair of desktop computer speakers connects in less than five minutes.
Set up the speaker labeled L (on the back panel) on the left side of the laptop. The R speaker goes on the right side.

Hook up the plug on the end of the left speaker cable, which is usually permanently attached, to the mini-jack on the connection panel at the rear of the right speaker.
Plug in the cable from the right speaker to the laptop's headphone jack, typically along the left edge of the keyboard.
Insert the power plug on the end of the transformer cable into the DC jack at the back of the right speaker and plug the other end into a wall outlet.
Turn on the speakers either by pressing a "Power" button on one of the units or turning the On/Off/Volume knob clockwise to switch on the pair.
Connect the speakers to the laptop before plugging them in to the electrical outlet. This prevents a power surge from damaging any equipment.
