Diagnostic indicators such as beep codes or LED codes are helpful to diagnose and resolve issues that your laptop might experience during start up. If the display cannot show any errors, your computer might emit a series of beeps during start-up.
NOTE: See the documentation of your Dell laptop for device-specific information about diagnostic indicators such as beep codes or LED codes. If the computer passes the power-on self-test or POST, the computer may give a single beep (some computers may not beep or beep twice) as it starts and continues to boot. However, if the computer fails the POST, the computer may generate a beep code or LED code indicating the potential source of the problem.
