Beep Codes

When errors occur during a boot routine that cannot be reported on the monitor, the computer may emit a beep code that identifies the problem. The beep

code is a pattern of sounds: for example, one beep followed by a second beep, then followed by a burst of three beeps (code 1-1-3) means that the computer

was unable to read the data in nonvolatile random-access memory (NVRAM). If the system loses power and beeps constantly when you turn it back on, the

BIOS is probably corrupted.
