HP Desktop PCs - Computer Does Not Start and Emits an LED or Beep Code | HP® Customer Support
Specific patterns of long and short light emitting diode (LED) blinks, or audible short beeps can help identify a variety of issues.
Diagnostic lights and audible beep codes are not available on all models.
Review the following to reference the light blink or computer beep sequence.
The red light blinks represent a major error category (long blinks).
The white light blinks represent a minor error category (short blinks).
A one (1) second pause occurs after the last major blink.
A two (2) second pause occurs after the last minor blink.
Blink error code sequences continue until you unplug the computer or press the power button.
Beep error code sequences occur for the first five (5) iterations of the pattern, and then stop.
