Table C-2 Diagnostic Front Panel LEDs and Audible Codes (continued) Activity Beeps Possible Cause Recommended Action Red Power LED flashes three 3 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Processor not installed (not an indicator of bad processor). 1. Check to see that the processor is present. 2. Reseat the processor. Red Power LED flashes four 4 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Power failure (power supply is overloaded). 1. Open the hood and ensure the 4 or 6-wire power supply cable is seated into the connector on the system board. 2. Check if a device is causing the problem by removing ALL attached devices (such as hard or optical drives and expansion cards). Power on the system. If the system enters the POST, then power off and replace one device at a time and repeat this procedure until failure occurs. Replace the device that is causing the failure. Continue adding devices one at a time to ensure all devices are functioning properly. 3. Replace the power supply. 4. Replace the system board. Red Power LED flashes five 5 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Pre-video memory error. CAUTION: To avoid damage to the DIMMs or the system board, you must unplug the computer power cord before attempting to reseat, install, or remove a DIMM module. 1. Reseat DIMMs. 2. Replace DIMMs one at a time to isolate the faulty module. 3. Replace third-party memory with HP memory. 4. Replace the system board. Red Power LED flashes six 6 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Pre-video graphics error. For systems with a graphics card: 1. Reseat the graphics card. 2. Replace the graphics card. 3. Replace the system board. For systems with integrated graphics, replace the system board. Red Power LED flashes seven 7 times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. System board failure (ROM detected failure prior to video). Replace the system board. Interpreting POST Diagnostic Front Panel LEDs and Audible Codes 193
