Question about HP Compaq d530 SFF PC Desktop

2 Answers

Refurbishing for a charity, PSU's failing regularly.

Does anyone know if this a common failing? We refurbish for a spinal charity, and the units are donated by a local hospital - but we are having a surprising number fail upon being connected to the power supply and switched on. The units are clean, and fairly free of dirt and grime. Any info would be welcome!

    Sorry, that wasn't very clear! Once plugged in, the power supply simply goes bang as soon as it is switched on at the wall. Sparks and a loud noise, followed by smoke! lol. To rule out a faulty power point or board, we have tried a couple of different places in the house. Not all fail of course, but 4 have just done so in a row! As these are donated, the numbers are limited - so becoming a little anxious! Just wondered if it was something common?

  • Volunteering Jan 18, 2008

    I wish it was that simple! The switch hasn't been altered - we check before connecting. Thanks anyway.

  • Volunteering Jan 18, 2008

    We don't have replacement units, if the PSU blows, we scavenge parts to keep for future use - but we are doing 100+units, we can't disconnect and test them all - I just wondered if it was a common problem, as we have not worked with HP/Compaq units before. They seem well designed, but we are at our wits end. Coincidence would explain the odd failure - but the count is now 6 in a row. We have changed power cords, boards, wall sockets, checked the current being delivered... etc. etc.

  • Volunteering Jan 18, 2008

    Checked the output from the wall, it is correct. We have already completed 30+ of these refurbishments, and after these failures, we connected up a couple of the previously finished ones - no problem. We don't really need a solution to replace these - just trying to figure out what is going on, as 6 in a row is too many - and these are all needed. We dare not try plugging in any more to work on unless we have checked all possibilities. It has brought the work to an abrupt halt!

    I purchased 2 refurbished D530's off of ebay with exact same results. Power supplies crackle and smoke immediately. I hooked up a standard 350W supply in one unit and it booted up normally. Definately junk power supplies.

This is a common failing on the d530 desktops - we run about 300 of these and have had quite a few PSU failures

    i know wat it is . we did it at school to torture the library/computer centre. its a little switch on the back off the power supply normally red , it should display 230 . move the switch so that you can see the numbers 230.this will work .funny why they set differently?

    wat you can try is disconecting the power supply from the boards ,hardrives.etc. and then plug them in could be bad/old power supplys and transformer in the power supply is faulty.

    very wierd unless the wall socket is giving out more than 230v. you can make your own costom power supplys . just use the cables from the power supply to board,hardrive.etc.connect those cables to a 230v to 12v transformer .Note! on 12v side 230v side 2 wall socket . these tarnsformers are found in many different house hold appliances .eg , cd players , kettles ,cellphone chargers.etc.

Why does my 50in vizio cuts off by itself

Please tell me that you didn't REALLY buy a REFURBISHED TV!?!?!?! And a Vizio to boot! The problem with refurbished units is that they rarely get properly tested. Many are returned with intermittent problems that do not show up at the refurbishing center, and thus they are resold with the same defect present. Vizio used to be the YUGO of the TV market. They have gained some credibility, but they still lag far behind the competition for reliability. What you are probably experiencing is a power supply problem, which is the most common problem with flat panel TVs, and a seemingly inevitable problem among Vizios.....usually a week or two after the warranty expires. I hope that you got some kind of warranty with the refurb....many are only 90 days which basically says - good luck sucker!

I have 22 Verifone Omni 3750 Terminals with all power supplies. They are in various states of needing refurbishing - like sticky keys and scratchy screens. Where can I sell them cheap?

you can always try e-bay. or you can look in your area for a recycler of electronic devices that will remove them from your property and dispose of properly or may refurbish them with the assistance of a charity group helping people get back in workforce. if you own outright you should look into recycling and they will remove your information from the machines in most cases

This has been a very common issue with this model series. Unfortunately there is no quick cheap fix. The correct way of repairing it involves removing the Chassis Cluster and sending it back to Mitsubishi for refurbishing. The cause of the problem is many capacitors are failing or have failed across 4 or 5 boards. The way the chassis is laid out it is most difficult even for the professionals
to totally tear it down and rebuild it. Average cost of refurbishing is around 600.00 to 800.00.
Because Mitsubishi is not going to support this model series much longer, I would look to replace instead of repairing it.
I hope this helps,

Old Computers.

not likely. They may not have anyone that's up to speed on that old of a system. I'd run a craigslist ad, and see if you can find a tech folk person, that likes to do this sort of thing(like the Victrola version for computers, eh?)
