troubleshooting your workstation pre-boot diagnostics audio signal pre-boot diagnostics audio signal When your workstation starts up, the BIOS performs Pre-Boot Diagnostics to test your hardware configuration for any problems. If a problem is detected during pre-boot, the Pre-Boot Diagnostics will emit an audio signal through the workstation's internal speaker. The Pre-Boot Diagnostics emits an audio sequence with two kinds of sounds. The first is an unusual series of tones that indicate an anomaly has been detected. This series of sounds also contains an electronic signal that can be sent through a telephone line to an authorized helpdesk or HP Support, if necessary. This signal cannot be interpreted by the human ear. However, it can be decoded by helpdesk equipment to extract the workstation model and serial number. The second type of sound is a series of long beeps that indicate a particular error. If you hear a series of beeps, you should count them as this will help you detect the cause of the problem. Number of Beeps 1 2 3 4 5 6 7 Meaning Processor absent, not correctly connected or ZIF socket not closed Power supply is in protected mode No memory, bad memory modules, incompatible memory module Graphics card problem PnP/WorkstationI initialization problem Corrupted BIOS.
