Virtually all PCs, including Dell laptops, have an internal speaker that differs from the built-in stereo speakers. The internal speaker beeps loudly when a hardware problem is present, such as when the laptop is powered by an adaptor that is not made by Dell. Unfortunately, the Dell BIOS configuration contains no option to disable the internal PC speaker of the laptop. However, a series of simple Windows commands can disable the PC speaker permanently until turned on via another command. This article explains the process of disabling the internal PC speaker on a Dell laptop running Windows 2000 or newer.

Log in to Windows with an account that has administrative privileges. Hit the Windows logo and "R" keyboard keys simultaneously to bring up the "Run" window, and type "cmd" into the window. Hit "Enter." This brings up the Windows command prompt.
Hit the "Ctrl" and "G" keys. The characters "^G" will appear in the command prompt. Hit "Enter." The computer will beep. This confirms that the PC speaker is currently turned on.
Type "net stop beep" and hit "Enter." This command disables the internal speaker for only the current Windows session. If you do not wish to disable the speaker permanently, stop here.
Type "sc config beep start= disabled" and hit "Enter." Note that there must be a space between the equal sign and the word "disabled" for the command to be processed successfully. This command causes the internal PC speaker to be disabled when Windows loads.
Hit the "Ctrl" and "G" keys again, followed by "Enter." If the speaker was disabled successfully, your computer will not beep.
Return to the command prompt and type "sc config beep start= auto" in the future if you wish to turn the internal PC speaker back on.
