Laptops are great for portability, but when compared with a desktop computer there are ways in which a laptop cannot compete. Laptop speakers are generally not as loud as most people would like. In addition, these speakers are known to short out or stop functioning rather easily. If this happens, laptop users can save a lot of money by fixing or replacing their laptop speakers themselves.
Unscrew all of the screws from the bottom of the laptop. The number of screws depends on the type of laptop you have. Generally, there will be one screw at each corner and one or two screws in the center on the laptop around the hard drive slot.

Remove the internal battery pack. On the bottom of the laptop there will be a release button next to the battery pack slot that you will have to hold down while sliding the battery pack free from the laptop. Slide the hard drive free after the battery pack has been removed. The hard drive is usually located on the left or right side of your laptop. After unscrewing the screws in step 1, you should be able to slide the hard drive free.
Unscrew the two screws at the back of you laptop that hold the hinges of the screen in place. Once the screws are removed, pull up gently on the screen until the pegs that hold it up are removed from their holes in the laptop's body. There will be two wires that lead away from the screen; make sure you do not pull up so hard that you disconnect these wires. Set the screen aside without disrupting its connections.
Separate the two halves of the laptop's body to expose the internal components. Once you are looking at the inside of the laptop, lift up and flip the keyboard onto its face. There will be a film-like connector that leads away from the keyboard. Set the keyboard aside without disconnecting the connector. If you do accidentally disconnect this connector, simply lift up the tab that the connector was resting in. Place the end of the connector inside the plastic tab and push the tab back down so that it holds that connector in place again.
Locate and remove the metal piece that covers the rest of the laptop's internal components. Once the metal piece is removed, look at the two halves of the laptop's plastic body and identify where the holes for the speakers are. Look at this location inside the laptop to find the speakers. Each laptop's speaker locations will be different, so this is the best way to find out exactly where your laptop's speakers are.
Check whether the speaker wires are connected. Your problem may be as simple as a loose connection. If the connectors were fully connected, you may need to replace your speakers. Buy a new set of speakers, making sure they are compatible with your laptop. Connect the new speakers where the old ones were connected. Reassemble your laptop.
If the new speakers do not work either, the problem may not be with your speakers but with your sound card.
