My computer is hp compaq d530 SFF when I turn it on nothing starts only green light blinking on the logic board. Please help me solved it.

Why would you want to try to repair a working green LED?
But you need a manual, to check what the blinking light means. See how it flashes, because the board is trying to tell you what is wrong with these flashes. Like perhaps bad voltage, or bad RAM or ROM? or lost all settings.

PLS REMOVE THE POWER CORD AND THE BATTERY FROM YOUR LAPTOP AND WAIT FOR 5 MINS THEN RE-INSERT THEM AND ON IT . SHOULD WORK

. PLS REPLY OR COMMENT. THANKS

If you have opened the system any time then you might have left any connection lose mainly the heat sink on the mother board if not opened then open the cabinet and fix all the connectors properly mainly heatsink

and then start your system.Your problem will be fixed

These computer are know to have bad capacitors. Check and ensure that you dont have swollen capacitor on the motherboard. The HP Compaq desktops are notorious for this. I am almost certain you have bad capacitors.

Enjoy the power of a PC.

Hello,

I have a similar problem:

My Compaq d530 was running fine until one day during plugging in a USB device (MP3 player) the system completely stopped working. The only thing which is active is the green LED on the mainboard.

I have checked several things and have found the following:
- IDE cable had burn marks!! (nasty)
- USB connection cable which runs from the front to the motherboard has changed in color. (darker green while all other connector have e more light white color.)

These are the signs of a brun out, but I do not have any solution to repair this.

Economically the best thing to do is buy a second hand (or new) system. (d530 are about 60 euros these days (march 2009). Hardware parts can maybe salvaged.

I found the drivers I needed at http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=316715&lang=en&cc=us&prodTypeId=12454&prodSeriesId=316713&taskId=135

I am running XP and used SoundMax Integrated Digital Audio for audio &
Intel Graphics Driver for Microsoft Windows 2000/XP for video.
