Error and Informational Messages

When you turn on the system, POST displays messages that provide information about the system. If a failure occurs, POST emits beep codes that indicate errors in hardware, software, or firmware. If POST can display a message on the video display screen, it causes the speaker to beep twice as the message appears.

POST Beep Codes

Beep codes are a series of individual beeps, each one equal in length. Write down the beep code you hear; this information is useful for your service representative.
