If your laptop audio is distorted or does not work at all, you can use this guide to replace the internal speakers. This process is moderately difficult due to a large number of screws and wiring to keep track of. The only tools required are a #0 Phillips head screwdriver, metal spudger, plastic opening tool, and magnetic project mat to keep track of the screws for each step. Be sure to handle the speakers and all wires with care, as they are delicate parts.
