Identify Beep Codes

POST checks to see that all the hardware in the computer is operating correctly. If a device is malfunctioning, an error or beep code alerts the technician that a problem has occurred.

Each BIOS manufacturer uses different codes to indicate hardware problems. Table 3-1 is a sample chart of beep codes. The beep codes for your computer may be different.
