This guide will show you the proper steps to replace your speakers in your Dell Vostro 1400 Laptop.
Computer speakers allow any audio played to be transmitted out loud without the use of headphones. Speakers that are not functional will produce either distorted sound or no sound at all.
Before using this guide, make sure to remove the hard drive, the battery, and the RAM.
Before beginning, make sure the device is powered off and disconnected from any power source.
