  • nathaniel292 Sep 08, 2009

  • nathaniel292 Sep 08, 2009

    Can this simple be a system intialization seeing that the motherboard was replaced? Because it is Vista Home Premuim, that is what I had on it and the HP site says that it takes about 25-30 mins sometimes... awaiting any new suggestions?

  • nathaniel292 Sep 08, 2009

    I have a dv9700 laptop HP I changed the motherboard and tried powering on which it did, but the HD lights are not respnding. HP said something about Vista initializing and it takes about 25-30 mins and then it should reboot so I am waiting for that. it's been about 25 mins. please offer some help...

  • nathaniel292 Sep 08, 2009

    I dont have recovery disk it all came preloaded. Once again this is a LAPTOP... you are asking me to take out the HD's there are 2 of them. The fan I can't disconnect.

  • nathaniel292 Sep 08, 2009

    I think it might be initializing... because the drives are spinning. Not getting any kybrd response so it is impossible to go into BIOS. Will wait for sme more time to see wht happens. Anymore suggestions if after the next 15 mins nothing happens? How long does it take to initialize?

  • nathaniel292 Sep 08, 2009

    in the intiailizng process should I be seeing activity on the HD light? because right now there is no activity/ the HD light is not blinking at all.

  • nathaniel292 Sep 08, 2009

    NO kybrd response, the board is brand new brought it from getpartsonline.com it came in a seealed HP box. I took out the HDD's and hook them up to an external reader that I have and I can see all the information on them. so it is strange that the laptop is not reading it. PLEASE HELP... !!!

  • nathaniel292 Sep 08, 2009

    All the ribbons are in and secure. Also when you get a new board like this one, all your passwords and stuff are all gone right? So how does it boot up then if the passwords and stuff are not there?

  • nathaniel292 Sep 08, 2009

Hi,
There should be no reason why the hard drive was not recognized by the system straight away when you powered up the new motherboard.
Now the type of hard drive is a serial ATA (SATA)
You can try to reset the BIOS by holding down the F9 key and hit the enter key.
Then go into the BIOS and see if the drive is recognized in the main page of the BIOS, if the hard drive is seen in the BIOS listen to see if you hear it spinning up, if you can hear the drive spin up then you may have to wait for the drive to initialize.
If you can hear anything from the drive at all then there is a possibility that the drive has locked up.

Please post back if you require anymore help or advise.

Good luck.

    Ah!!!
    You have two drives in the laptop, have you gone into the BIOS and changed the boot order?
    Try changing the boot order of the HDD's to work out which drive holds the operating system.


    Regards.

    Yes there should be a LED indicator light that shows HDD activity, if the LED indicator is not showing then the drive is either dead or its not plugged into the motherboard properly.

    Check in the BIOS to see if both the drives are there.

    Check that the drive is connected to the motherboard properly, also check that the other hard drive works in the same port.
    Take both drives out of the laptop and plug them back one by one and check the bios to see if they are recognized.

    Do you have any keyboard response at all? this does not sound right.

    Check that the ribbon cable that connects the keyboard to the motherboard is seated properly and that it's clipped into place.

    Can you also tell me if the replacement motherboard is brand new or second hand.

  • Lee Hodgson
    Lee Hodgson Sep 08, 2009

    Hi,
    You have checked the HDD's and they work as you view the data on them.

    Take out the system memory, clean the brass contacts with a pencil
    eraser and wipe the eraser dust off and then reseat the memory, make
    sure the memory is clipped into place and is seated firmly then boot the laptop up to see if that makes any difference.

    If there is still no change then this leads me to believe that there is possibly a fault with the motherboard itself or you have assembled the laptop correctly.
    I recommend that you completely disassemble the laptop and start again from scratch taking particular attention to all the connections and the processor.

    If you still end up with the same result then i would be 99% sure it's a faulty motherboard.
    If that's the case return the board and have them swap it for another one.


    Good luck.

    Only the BIOS password is cleared with a new motherboard.
    If you have an HDD password or Windows password they will remain.

There are many things that can cause this type of symptom.
Is it failing on battery only? May need a new battery.
is it failing when plugged into the power adapter?
The adapter input jack will fail over time and need to be replaced.
There is considerable mechanical stress on this part, and It will fail where the jack is soldered to the circuit board.
Internal circuits can fail. Maybe a new laptop will be cheaper than repairing this one.

does the monitor light up when turned on if no recommend completely new computer M/board and CPU as this is the quickest and probably the cheapest way out of your problem.

any water near M/board is fatal you only need 1 connection with water and that is that

Asus mb wl300 amd 64 4000+ won't boot to bios.


To make sure it isn't anything else, pull all cards, and drive cables from the board so the only thing left connected is the power connectors to the motherboard, the speaker, and the power button. Pull all the ram cards.

Now power up the computer. If you hear a series of beeps then the computer recognizes there is no ram on the board. At this point I would take the power supply out and have it tested. If you do not hear a series of beeps I would still have the power supply tested as it could be the 12v is fine but the 5 and 3.3 volt side is bad.

If power supply tests good then I would replace both the motherboard and processor. You take a risk of burning a new processor if it's the motherboard causing the problems.

Problem with System booting Compaq Presario 12XL500


Check your memory sticks to make sure that they are full inserted and did not come loose. Check the power from power supply going to HD. Make sure it is getting power. You can also remove your motherboard and test components with an ohmmeter to see if there are any burned out components which is very possible. Have seen bad boards and bad power supply's both cause your problem

PS2 slim Power Problem - Light is red goes green but nothing else.


Hi Leostg,

 

I have seen this a couple of times.  Lightning or an overload has burned up the motherboard. Its not a fuse, its a fried Emotion Engine processor.   Best advice on dead motherboard is to probably total it unless you can get a low price motherboard replacement. My cost on a new motherboard for slim is about $55.  If you want it fixed, replace the motherboard.  Really you may be able to get another Slim for $55 or less. If you look on ebay  for another motherboard do not take any chances on used motherboards. Go for a broken slim model that will boot up but want read discs. When you get one that boots up, use its motherboard in your Slim.  This will be your best deal at getting your slim up and running once more.

Please give me a Solved vote. I believe you only get one vote and its locked.   I have put a lot into your solution and hope you will show appreciation by voting solved.
