How to Disable the Internal Speaker on a Dell Laptopby Mike Venture
Windows and other operating systems need to be able to alert users to events and problems. A common way to do this is through audio cue, but in some cases the computer may not have speakers attached, may not have a sound card or may not have the proper drivers installed. To deal with these hurdles, companies include a simple speaker or speaker service that does not require drivers or external amplication in their systems. This is often called the "system speaker" or "beep speaker" because the cues are always beeps. However, there are times when you want to use you laptop with absolutely no sound, such as in a library. For these times, you can disable the system's internal speaker.
Click the "Start" button and then "Control Panel."
Click "Device Manager."
Click "View" and then "Show Hidden Devices."
Expand "Non-Plug and Play Drivers" by clicking the plus sign next to it.
Double-click "Beep" in the list.
Click the "Driver" tab.
Click the drop-down list box and change it from the current setting to "Disabled," click "OK" and then close Device Manager.
