Remval of power supply from hp d530 compact desktop

I'm not going to go through a list for you, but I can tell that you don't have many options. The HP Compaq Business Desktop D530 uses a small form factor which means you don't have the same space as normal desktop users inside of your machine for the vast majority of display adapters. You would need at least a medium form factor for that.
The other problem is that your power supply is only 185W and can't supply the the amount of power needed for most desktop class display adapters.
The machine you are using wasn't designed to ever be used for gaming, and it shows. You would need to get a bigger computer case and higher watt (around 400 to 600 watt) power supply to support most desktop display adapters.

you have 2 small wires connected with piece of plastic on motherboard , close to that says" bios pass" take that out ,that plastic and you won't have password on bios , or turn off computer , take it off electricity power and take out battery from MB and press button for starting few times to drain electricity that is left on power supply , then get back everything and you won't have pass , hope ti helps

It sounds like the power supply is defective and will need to be replaced.
I hope this helped.
Good luck and have a great day.

the top cover should slide off from the back end remove any swrews at back before sliding cover

hello...remove the memory then make clean and take it back then to boot the unit..Good Luck and Have a nice day..^_^

check the voltages of cable coming out of ups , if cable is faulty replace cable
next try to check your smps by sharting green & black cable

I removed the cover, drives, motherboard, and the back plate and then the power supply just slide out the back of the case.

it is depend up on the power supply connector and it will give the output according to the smps you can do one thing try with installing other fan and see is it in perfect rotation. bye
