Hello. When I install alternative power supply (with more power)on my HP D530 SFF a POST error masssage like "920-Fan Command 2 Pin Connector from Power Supply Not Connected" occurs... How to disable it? My new power supply hasn't 2 pin connector...Hidden BIOS setting or else??? Perhaps what kind of (model of course)power supply *min 200 Watt you prefer. Solution of this problem is very important to me.

Most HP computers use custom power supplies which can not be replaced with standard ATX power supplies. The Technical Reference Guide is not available for the d530 so I can not check exactly what incompatibilties there are between the d530 SFF power supply and a standard ATX power supply.
Hope this helps.

I found The Technical Reference Guide for this model (file name: 340154-001_d330-d530_TRG.pdf). Figure 7-3 in that document describes power supply cabling for the SFF systems->see below attachment for details. But I still don't know how to connect the variable fan speed to connector P9 on motherboard. Does anyone help me? |

The power supply fan signal to the motherboard is an HP custom feature and is not implemented in a standard ATX power supply.
I have seen reference in this forum of connecting a resistor between fan signal pins to fool the motherboard into thinking the fan is connected. I do not know if this would work for you situation or not.
Hope this helps.

John is correct. The HP system board is designed to check each connector that is used in the original configuration. I'm afraid the only way I have ever been able to disable this error message is by actually connecting the power supply to this 2 pin connector. If you insist on the 3rd party power supply, this POST message and pressing F1 may just be part of your start-up routine for as long as you have this computer. |

I found a solution! Just connect resistor 1kOhm between pin named Fan Command and GND. It's really work. And there's no error at startup anymore... |

Hi,
Same problem. The HP power supply dies and its much cheaper to buy a third party replacement. You will find the onboard speaker has a 2-pin connector that fits perfectly into the Power Supply fan port (just between the RAM slots and the IDE ports). Just unplug the speaker from its spot on the side of the motherboard and put it into the power supply fan port. The bios just wants something (anything!) plugged into the fan ports ... it cant tell the difference between a fan and a speaker ... and now for my next trick I'll explain how to secure loose expansion cards with blue-tack ... |

A neon won't work it takes 90-100 volts to conduct and you may have 5 volts try the 1k resitor |

hello, I am having the same problem with my computer and tried everything and still nothing works. now the computer turns on for 20 seconds or sometimes less and shuts off. My computer is a DC5000, i recently put a new power supply in 430W. two fans the are 3 pinned and one connected to the power supply, I looked over and over and still nothing changes.
How do you Jump it. I am trying to get this to stay on long enough to load everything and so I can load the windows program. there is no diagram or manual for the motherboard.
please help me |

Hi,
Seems this thread has been quiet for a while but perhaps someone can help me by telling me what third-party ATX PSU they used?
The standard PSU is an odd shape and I haven't found any like it online so please, tell me what options are available.
I have just bought a D530 SFF and if blow ups are common then I would rather get a new PSU and avoid it happening.
Many thanks in advance.
