Internal laptop speakers can be disabled by several methods. They can often be fixed by simple troubleshooting. The problem could be that the sound is turned all the way down on the speakers' external volume control or by the operating system sound control. The speakers may be disabled or muted. More challenging problems include incorrect or ineffective hardware drivers or old BIOS that is not compatible with the current operating system.
