Hy hp d530 won't turn on

I turn the power button on and nothing happens. The green light on the mother board blinks, but nothing else happens. the fans don't go on either. i've unpluged everything and it still won't turn on. a friend suggested that the memory slot is defective so i should replace the motherboard. this is a refurbished machine and is only a couple of months old.

help please
thanks

    NO sorry no sounds at all. If i keep the power button in it will flash and the green light on the motherboard would keep on flashing.

  • ngibbs691 Dec 09, 2008

    no beeps an led blinks green.

  • ngibbs691 Dec 09, 2008

    voltage is set at 110v. the lights on the keyboard don't blink. the green led on the motherboard blinks. If i keep the power button in, the power on light would blink (green) as well. I tried unplugging everything to check if any particular item was causing the problem, but i got the same result. Monitor says no signal and pc does not turn on.

  • ngibbs691 Dec 09, 2008

    i tried both memory chips, the 512 and the 1gig and got the same result.

  • ngibbs691 Dec 09, 2008

    no i don't but it's a 2.8MHZ up to 4gig pentium 4. i have the slim model not the micro tower. i bought it on comp geeks, it's a refurbished machine.

  • ngibbs691 Dec 09, 2008

    yes that's correct it is a 4 dimm. I have 1 512mb and 1 1gig so totaling 1.5 gig ram. it's a 2.8mhz processor.

  • ngibbs691 Dec 09, 2008

    Speed of memories are 512 and 1gig.

    I did pull out the battery and out it back, no change.

    i also pressed the cmos button, but it did not do anything.

  • ngibbs691 Dec 09, 2008

    Thanks Jonathan, it worked fine for a couple of months. one day it was turned off and the rest is history. i did experience a couple of power outages a week or so before, but don't get any scent of burnt electronics from the pc.

  • ngibbs691 Jan 06, 2009

    don't have the cd. i was told the memory slots my be burnt, does this sound right?

    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.

    From what I recall, each memory bank pair must have memory chips of the same size. Thus, if you have a 1Gb and a 512Mb chip, then this would present an issue for the system. I don't know if that means it won't start at all. Did you try booting up with just one chip installed, in slot "0"? If you tried this, once with each memory chip, then you likely have a faulty motherboard. Motherboards are too expensive to fix--you just replace them. I don't know what the rest of your system is like, so you'd have to decide if there were enough usable components inside to warrant replacing the motherboard. You would also want to do this privately, as taking it to a service center will likely end up costing you more than if you went out on CraigsList and acquired a used and well working computer. Good luck!

    If your power supply had completely failed, you would not get any power whatsoever. So it sounds to me like it may be OK. Were you able to get any further? If not, I suggest trying to boot from a rescue or installation CD. If you can boot from that, then your issue might be your hard drive.

    I suspect that those memory modules are not supported by the motherboard, but it's hard to be sure without knowing exactly what motherboard you have.


    Checking the web I find this


    http://bizsupport2.austin.hp.com/bc/docs...



    Which on page 17 states that the D530 motherboard does not support memory modules beyond 400Mhz. I appreciate that this isn't exactly the same model of D530, but the HP support forum had a comment on from a HP guy saying that the only difference is in the positioning of things like USB ports etc..


    Therefore, a question I probably should have asked at the outset... "has it ever worked since it was refurbished?"


    If the answer to that is "no", then I think somebody upgraded the memory on the PC during refurbishment, and put in the wrong modules.


    Can you let me know what you think of this idea please?


    Thanks,


    Jonathan

    Can you tell me the speed of the memory modules please?

  • Solo4665
    Solo4665 May 11, 2010

    Another idea.. can you take out the CMOS battery, leave it out for say a minute or so, put it back in, and then try to power on again?


    It looks like a silver, flat coin. Kind of like the batteries you get in watches.

  • Solo4665
    Solo4665 May 11, 2010

    I think you should have 4 DIMM (Memory module slots). They should be colour coded, blue and black.  Can you confirm this please?


    Also, can you tell me the speed of the DIMMS that you have? there is normally a sticky label or something on them like 333Hz.

  • Solo4665
    Solo4665 May 11, 2010

    What sort of motherboard is it? Have you got a part number?

  • Solo4665
    Solo4665 May 11, 2010

    Please try taking out the memory chips, and then testing to see if it boots with each memory chip in turn. (i.e only 1 chip in at a time)


    Also, can you ensure the processor is secure in it's slot by pressing down gently on it.

  • Solo4665
    Solo4665 May 11, 2010

    Looking at page 14 of the manual - what can we learn from the keyboard LED's? ie. has the rom failed?

  • Peter Sturniolo
    Peter Sturniolo May 11, 2010

    Is the power supply set to the correct voltage? Should be 110V in the US, 220V just about everywhere else; make sure you unplug the power supply before changing any settings.

  • Solo4665
    Solo4665 May 11, 2010

    Are there any beeps from the machine?
    Does the LED blink red?


    http://bizsupport2.austin.hp.com/bc/docs...



    This may be a useful starting point..

  • Peter Sturniolo
    Peter Sturniolo May 11, 2010

    Do you hear any low pitched beeps when turning it on? That would indicate a problem with one of the memory slots/memory itself.

Compaq Presario SR2020NX will not turn on at all. Any ideas, people?


ah a tower

you check the power source output
this can be replaced as a whole unit

at power up should be a beep
if the mother board is good it will start up its default
before loading from the hard drive

make sure the dust is removed from all the internals
clean all the contacts
the fans and cards and main board

Gateway 825gm wont tun on. just replaced on/off switch. greem light on power supply and mother board blinking green


Make sure the small cable from the switch to the mother board hasn't come loose. It comes loose fairly easily when reinstalling the cooling fan plenum. Its happened to me twice. Its even possible to plug it in the wrong place. Doesn't hurt to double check.

My a730n computer will not turn on. The green light flashes in the back. Local frys tested power supply and said it was working. Fans dont come on...nothing?


it could be a mother board problem or Power supply issue. Even if the power supply works it wont supply required voltage to some components.Its better you get a new power supply and test it.Still its not working it could be a mother board issue.There will be a chance for power button issue also.

System was up an running then, Then shut down


It sounds to me like it overheated and something burnt out, but I could be wrong. The main pieces in a desktop computer are: power supply, motherboard, cpu, ram, and video card (which is on the motherboard for lower end systems.)
Each one will need to be properly tested to find out which part(s) is(/are) failing, and the failing part(s) will need to be replaced.

Orange light, no start


Well it could be the power supply, but, first try removing all the cards on the motherboard except the video card (remove and reseat that) assuming the video is no built in. Then turn it on. See what happens. Post back with results

Amber light on power button


Check to see if there are any loose connections to the memory cards on the memory board. Make sure the data cable to the drives are connected properly. Is the fan in the power supply on?

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?
