Table 2-11Solving Hardware Installation Problems (continued)

Power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause

Solution

 

 

Memory is installed incorrectly or is bad.

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. Power on the system.

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.

Power LED flashes Red six times, once every second, followed by a two second pause, and the computer beeps six times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause

Solution

 

 

Graphics card is not seated properly or is bad, or system board is bad.

For systems with a graphics card:

1.Reseat the graphics card. Power on the system.

2.Replace the graphics card.

3.Replace the system board.

For systems with integrated graphics, replace the system board.

Power LED flashes Red ten times, once every second, followed by a two second pause, and the computer beeps ten times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause

Solution

 

 

 

Bad option card.

1.

Check each option card by removing the cards one at time

 

 

(if multiple cards), then power on the system to see if fault

 

 

goes away.

 

2.

Once bad card is identified, remove and replace bad

 

 

option card.

 

3.

Replace the system board.
