Replacement of motherboard of HP DV5-1000

I accidentally spilled a drink on my laptop (DV5) - 1000 Intel.  I immediately turned it upside down, to let the liquid flow and close.  After cleaning, I restarted the laptop and everything was fine.  I thought I had all of the fluid out of there, but apparently not.  After about an hour of use, the laptop suddenly stopped as if the battery had been removed while running alternative.

The power button on the laptop would not... no light, no action.  I disassembled the laptop (I did this several times before, to replace the broken keys - they wear out prematurely; now mostly use an external mouse) and discovered traces of juice dried on a small area of the motherboard.  With the help of buffers and rubbing alcohol, I carefully cleaned all messes, let it dry overnight, then reassembled.  Unfortunately, this failed.

So, I have to assume that a component of the motherboard was short-circuited and is now non-fonctionnel, preventing the working laptop.  Frustrating to think it may be a single transistor that is the culprit, and I don't have the skills to troubleshoot it.  Therefore, the only hope is a new motherboard.  While I replaced front CPU and apply the thermal paste, I am a bit perplexed about how to deal with the GPU.

Which brings me to my question...

There are many slight variations with the cell phones of Pavilion DV5 series.  While many parts is compatible, I'm not sure about the motherboard once the appropriate processor is selected (AMD vs Intel).  He needs to be a very specific model?  There are several DV5 motherboard replacement parts available through various sources, but I'm not sure how small it is, once the CPU is put in correspondence. I have the impression that some may designed for specific GPU.  Mine has a 512 MB GPU nVidia.  But I do not know if it is possible to remove it and install on the new Board of Directors... They all come with a pre-installed GPU?

  • Replacement screen dv5-1000 options

    My DV5-1000 has a cracked screen. According to the service manual, it is a WXGA, HP part 484367-100 and is made by to THE Optronics. I could not find one of these at a reasonable price, but came across a similar DV5 with a keyboard mash that someone stepped on while it was open. It has a screen WSXGA + made by LG. In addition to the keyboard its motherboard also seems to be broken, but I bought the computer laptop all for $25 just for display. His memory alone is worth it so I got really little to lose.

    I removed my cracked screen and installed the WSXGA +. I worked, so now I can get back all my files etc. Unfortunately, the display appear washed out and green and hard to read. I wonder if the screen itself is bad, or if the WSXGA + does not work as a replacement for my cracked WXGA.

    I asked my business of the Department, supporting hundreds of HP laptops. He told me that the screen WSXGA + should work as a replacement for my screen WXGA. He thinks that the display is faulty and recommend finding another WSXGA +, since my cracked screen gives me an excuse to upgrade.

    So, is it good? Should I find another WSXGA + or am I limited to an exact replacement for my cracked WXGA?

    The higher resolution screen is not a valid replacement. He will drive the video but it will look very funny as you can see. You must obtain the specific display panel I can't wait to tell you. They are very ruthless.

  • Want to 800-060: reactivation after replacing the motherboard

    I bought a HP Envy 800-060 with Windows 8 pre - install Amazon in July of 2013. It was an incredible computer since that time, and when the free update of Windows 8 for Windows 10, I did immediately released. Recently, however, the motherboard has failed on the computer. It would not stay same POSITION, and after much troubleshooting, I finally decided to replace the motherboard. Now that the computer is running again, I guess that the motherboard change was sufficient for the operating system to think that it is no longer enabled. I was never provided with a key of Activation of OS (Win8 has been pre-installed), and Microsoft has suggested that I contact HP to find the original key. I've looked everywhere on the chassis and inside the tower for a valid Windows activation key, nothing helps. I tried to find a phone number to call for support, but my product is outside the guarantee. I don't need advice or troubleshooting tips (so I don't pay the $59.99), all I need is my activation key valid Windows based on my serial number of the product. Anyone know the best way to achieve HP with this problem and have it is resolved?

    Thanks in advance!

    The unfortunate, is that your original product key has been incorporated in the firmware original by HP motherboard UEFI when the PC was built.  There is no way to recover this key now.

    HP retains no record of keys to individualized product corresponding to individual computers, so they won't be able to provide you with the original key - and they are under no obligation to provide you with a SECOND key, that you didn't do the replacement of HP hardware.

    With the product now being out of warranty, it's really call HP or not you upload support - and the experience I have had with older equipment-, they do that, there's just no way around IDs.

    HP customer support is really the only way you have to get support.  If they don't help you for free, because your PC is out of warranty, there is nothing we can do about it on this forum.

    I am trying to replace the motherboard on a L750-16 X. I think that I need this A000080670 card, which is available. Under the RAM slots the sticker says A0000806709B141422W. I'm not sure of what the average figures and additional letters and I was wondering if anyone knew if it is compatible.

    Thank you very much

    I don't know where you want to get the new motherboard, but if you want to buy it by some authorized service they should now what they offer.

    I don't know if anyone here has the same machine and can help you with this. What you can try is to contact the nearest Toshiba service provider in your country and ask for help.

  • a610n - fan error of the system after replacing the motherboard

    Hi all

    I just replaced the motherboard on my system (phone http://h30434.www3.hp.com/t5/Desktop-Hardware/M2N68-LA-Narra-2-Replacement/td-p/3711774) and now I get this error when starting: Fan failure system, PC service to avoid any damage. I thought it was the CPU fan but he was running and after some research, I realized that he could talk a case fan.

    As a side note, the motherboard, I had was a little different and missing 2 connections that seem to be the front mic/headphone and USB ports.

    Now, the case's fan then what really is the problem? Any ideas anyone?

    Thank you

    -Panos

    The rev3.02 of M2N68 - THE Committee a case fan rear 3 poles. See here.

    The CPU fan is a 4 pin cable and attaches to the appropriate header to 4 pins on the motherboard. See the representative schema above.

    As for you, another question, the front USB port attaches to a USB connector on the card.

    I was offered a replacement of THE KSWAA - 4983P Rev 1.0, 2009-08-04, K000092510.

    Is the K00... number important or is it just a serial number / lot number.

    Any help would be appreciated.
    Concerning
    Chris

    Googling K000084300 you will find information on the optical disk drive, but using the number K000092510 result is news on motherboard for Satellite L500.

    I ve Exchange motherboard only once and I have identified the right one based on the part number of the laptop (PSLxxx).
    I don't know where did you want to buy this new motherboard but the store should have information about compatibility.

    Anyway, AFAIK this K000..., number will be used for ordering parts.

  • Qosmio F10: RAM upgrade issue after replacing the motherboard

    In 2006, when my F10 - 128 fell down as a fault of the video card, Toshiba has replaced the motherboard (865 PM) of my F10 by a new one with the video card installed in Go 6600.
    When I came back, I noticed that the same RAM modules have been installed (2 x 512 MB DDR 333 Mhz) as I previous had on the old motherboard.

    Then, I assumed that I could easily upgrade to DDR2 RAM, I realized that this type of RAM supported by the new motherboard installed (915 PM?). But the modules DDR2 Ram (Kingston 1 GB SODIMM (KVR533D2S4 - 1 G) 533 MHz) that I ordered is simply not in the storage media... The notch in the module is placed differently that the modules of RAM DDR.

    If the jury has been replaced by a newer version, with the video card Go 6600 (PCIexpress), how is, I have a Council that can not support DDR2?

    Here, I am really confused. Someone at - it advice please?

    > If the jury has been replaced by a newer version, with the video card Go 6600 (PCIexpress), how is, I have a Council that can not support DDR2?
    I think the jury is still supported DDR2 memory modules, but the allocation of the memory pins could be different.

    You should contact the ASP in your country and ask for the compatible modules.

  • Satellite P850-12Z: No. Wake up on LAN and no BT after replacing the motherboard

    Hello

    I got a Satellite P850-12Z Code: PSPKBE
    Recently, the support of Toshiba replaced my motherboard

    I thought that WAKE ON LAN is disability, and my Bluetooth does not work.
    I go to Toshiba Bluetooth programs and not work

    Can anyone help me?.
    Thank you

    Hello

    > Recently the support from Toshiba has replaced my motherboard
    In my opinion, you should get in touch with the guys from service again once who replaced / fixed on your laptop.
    The laptop should work properly once the service has replaced a faulty part. If it s not the case, you guys should check once again!

    I put t know what card WLan do you currently use, but AFAIK the original build in WiFi card was Intel and this wireless network adapter supports BT as well.

    So I think you should ask the guys once again unites what s wrong with you

  • Qosmio F10 recover after replacing the motherboard

    Hello

    I'm having a problem with my Qosmio F10 recovery. It won't boot from the CD, I get a message "media test check the cable failure".
    I tried everything I could find here on this issue without any results. Then I read somewhere on this forum that this recovery cd would not work if the laptop has been repaired and has a new motherboard. This is excatly the case.

    I got a new motherboard and CD/DVD player put some time ago.
    How can I make it work again?

    A.

    > Then I read somewhere on this forum that this recovery cd would not work if the laptop has been repaired and has a new motherboard. This is exactly the case.

    Who replaced the motherboard? THE ASP?

    Well, usually the recovery CD should work after the replacement of the motherboard.
    I presume that the parts have been replaced with exactly the same parts and so it should t be a conflict between the recovery and the new motherboard CD.

    Hello

    How old is your machine? If you still have your warranty, so why not give your machine to a local service partner?

    So if you don t give something on your guarantee you can trade your coins. But to look for the pieces on google and you won´t get any help from toshiba (e.g. manual disassembly or something similar).

    I tried long before your request and I made my experience that if you want to open your machine your completely on your own.
