HP Compaq d530 PSU Repair > How to remove the PSU from a d530 SFF PC

Got the replacement for 308439-001 or 308617-001? Read on to find out how to remove and replace it.

Power Supply Unit Removal

Although the PC has been designed to be mostly tooless when it comes to basic servicing, HP has made it overly difficult to remove and replace proprietary components such as the PSU. HP have made the assumption that the PSU should almost never fail, whilst the motherboard is designed to be easily replaced if it ever does fail. More often than not, the reverse is true - the PSU has a fail rate at least 10 times that of the motherboard!

If you follow these instructions, you will save yourself a lot of hassle trying to figure it out yourself. At most, only about 5 screws need removing. This method also is the least complex, and will take about ten minutes.

Before you start, make sure you have a TORX screwdriver bit that will fit the screws on the back of the d530 PC. You may also need scissors or side cutters to cut a cable tie or two. Other than that, additional tools are not required.

Removal instructions

Step 1 Position the d530 PC on a work bench so that the back is facing you.
Step 2 Open and remove the lid (hood)
Step 3 Remove the front plastic cover (the three clips hold it in place). Remove the PCI riser backplane card.
Step 4 Using a TORX (star) screwdriver bit, remove the screws from the back of the PC. This includes the uppermost left and right, the one at the power supply, and also the ones securing the hood lock. The hood lock uses security TORX screws (they have a centre post), whilst the rest of the screws can be removed using either a torx bit or a flat blade screwdriver. You can opt not to remove the hood lock, if you're careful enough when removing the panel so as not to foul the hood lock PCB onto the side of the casing.
Step 5 Lift up drive tray
Step 6 Slide the motherboard out to clear the back panel, by lifting the green release catch and pushing the motherboard back about two centimeters so it lies loose (otherwise the back panel cannot be removed in the next step).
Step 7 Carefully pull the top of the back panel away. Once it has reached an angle of about 20 degrees, the bottom can be pulled out. Be careful not to damage the copper clips (they help create good electrical contact).
Step 8 Remove the black tamper switch (the one with the red and black wires; the switch is above the power supply unit, next to the speaker).
Step 9 Lift the motherboard up on the left side, and rest it on the side of the case. The other side of the motherboard can rest on the cutouts on the bottom of the case, which will stop the board sliding back down. Try not to lift the motherboard by the centrifugal fan, otherwise you will put excessive strain on the CPU heatsink bracket, which can break.
Step 10 Disconnect the 20-pin ATX, 4-pin 12V and the 2-pin 'Fan Command' cables from the motherboard.
Step 11 The power supply can now be partially removed by sliding it out.
Step 12 Wiring looms are tied with zip-lock cable ties. On some models, the zip-lock fastener includes a tab, which can be used to release the lock, allowing the cable tie to be opened and re-used later.
Step 13 Untangle the power supply wires from the other looms. Remove the power supply.

Re-installation of the replacement

Once you have your replacement unit, re-installation is the reverse of the above. Be certain that none of the wires get poked into the fan grille of the PSU. If the PSU fan is jammed, it will overheat and blow up again!

This was extremely helpful. It's funny that the PSU is the hardest thing to remove, but the first component to go.

Thanks a lot!

I have one of these units.the fan on the power supply stopped,so being an old man of 80 and not much dough.I decided to take out the power supply myself,after removing a number of screws, and a bit of leverage I got the damn thing out,without touching the mother board,the fan is removed,the whole power supply is sitting on the top its still connected,I have a household fan blasting air in the top as the top plate is off the power supply it has been running all day for almost a fortnight,and it will stay that way untill I can get another fan and shove it all back together,I thought you might like to hear this story,Thanks again a good site Mr R gray

Your description was extremely helpful. Today I replaced a blown-up PSU in less than 1 hour, following your instructions.

Many thanks from the Netherlands

I have a HP Compaq netvista IBM which I have had a few years but I am wanting to change everything out of that tower into another tower but I am having problems removing the motherboard.
The problem I am having is.... I have removed all the screws from the motherboard, it seems to lift when I lift each corner except for the corner where the fan sits.
I have looked and looked to make sure there is not another screw left in but I can't see one.
Is there something else I need to remove to get the motherboard out? Or do I need to remove the fan etc to remove motherboard?
Regards
jayne

Missleading
No need to remove the motherboards it is a 5 min job to remover the PSU's in these.
admin, Thu, 10 Jun 2010 09:10 pm:
Sorry Bob, but you are incorrect. The HP Compaq d530 Small Form Factor PC power supply cannot be physically removed with the motherboard in place because the angled fan section gets in the way.

If you look at the photos properly, you will see the motherboard must be moved out of the way before the PSU can slide back and lifted up prior to removal. Otherwise the fan on the PSU will foul the motherboard.

I have repaired hundreds of these PCs, and if there really was a way of getting the PSU out without moving the motherboard out of the way, I would have done so.

Just because you have removed a power supply from a normal ATX PC case doesn't make you an expert on a big-brand proprietary PC form factor.

CAN WE THROW THE HOODLOCK AND TAMPER SWITCH AWAY when we reassemble?

thanks sooo much
admin, Tue, 22 Jun 2010 12:32 pm:
Yes, the tamper switch and hood lock don't affect the way the PC operates and can be removed if you prefer. They're only useful in educational and business/corporate settings where centrally managed inventory systems can detect if someone is trying to tamper with the PC. The hood lock can also be operated remotely by the sysadmin though network management (as long as the software is installed).
