Inspiron 1520, replacing motherboard

Jump to solution

Hello

My Inspiron 1520 just died a few days ago. I did the tests to know what  part is failing and I'm pretty sure that the problem is in the motherboard. The laptop garanty is expired, so I want to replace the motherboard by myself. I think i would have no problems in replace the piece, the thing is that I'm not sure if I will need some software to switch on the computer. Is it necessary to flash the bios? I have not the CD's that came with the laptop, so I dont know if I can use a bios flash-cd made by myself (I read some tutorials about it and I can do it, but I dont know if it will work).

I mean, if I replace the motherboard, and the rest of pieces work correctly (I have xp and suse installed on the hard drive), will the computer run without any aditional task? or must I flash the bios before the laptop can start?

Thank you very much.

Hi,

Thank you for your quick response. It appears to be an issue with the memory slot (motherboard) of your computer and need replacement. You need not to flash the bios from CD. You can simply update the BIOS of your computer. Please make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

If it's blink - blink - solid green without the memory, that's a video card failure.

I suspect your mainboard was fine and it's the video card that is bad.

Hi Dudo22,

Could you please let me know the issue that you are facing with the computer.

Motherboard of the computer is not a customer replaceable unit and requires lot of technical expertise. However if you are comfortable replacing the system board of your computer, you can refer to the link: ftp://ftp.dell.com/Manuals/all-products/esuprt_laptop/esuprt_inspiron_laptop/inspiron-1520_service%2...

Copy and paste the above link in address bar of browser to get detailed instructions on replacing system board of computer. You would not need any application to start your computer however it is recommended (not mandate) to update the BIOS of computer before start.

Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved. 

Please reply with findings.

Oh I forgot to report the problem.

The computer just died a few days ago, I got a blue screen telling me that there was a hardware problem. After that, the PC didnt start, I press the start button and the screen does nothing. I removed the hard drive, the CD device and the RAM cards and started pressing fn: the lights code was: light + blink + blink. After that I started the laptop with each memory in each RAM place and with both RAM's and the code was: light + light + light (2 seconds and then the lights turned of). That indicated that there was a problem with the memories, so I used my memory cards on other computer and they worked perfectly, and my computer didnt change his behaviour with another rams (that worked fine on other lapton). So I think all of this indicates that the problem is in the motherboard. Is this correct?

Re: Inspiron 1520, replacing motherboard

Jump to solution

Hello again,

I didn't replace my motherboard yet. I'm having some issues with the new piece that I have to buy. I have read that this motherboard model, the WP044, is equipped with two types of socket depending on the processor and two types of chipset as well, Intel PM965 and GM965. My processor is a Core 2 Duo T7100, so I need a socket P (also known as 478B or 478MN, please correct me if I am wrong), but I am not sure if both chipsets are compatible with that processor. This is important because sellers sometimes don't even know wich type of motherboard are selling. If you could help me with this it would be great.

Thank you

Hi Dudo22,

Inspiron 1520 is shipped with GM965 / PM965 chipset and the processor (Core 2 Duo T7100) is compatible with either of these chipsets. For more information on this processor, you can refer to link: http://intel.ly/S22YTI There should not be any problem installing it. Part# WP044 is for the discrete motherboard. If you are planning to get a discrete motherboard for your computer, you must get a discrete video card for the same. 

In case you are planning to upgrade to a UMA motherboard, you can go for part# WP043 (motherboard) or WK076 (motherboard service kit with daughter board included). 

Please reply in case you have any further questions.  

Thanks and regards,

Thank you very much

There is no problem with the video card, I only want to replace my broken motherboard, so the rest of pieces still work and I can use them with the new motherboard.

Just a last question. I am really confused about the sockets denomination. As far as I know, Core 2 Duo processors work on sockets P, but I have seen that this socket is also known as socket 478B (this is the socket of my broken motherboard), is that correct? The thing is that some motherboards for sale have a socket named 478MN, the pins configuration is the same than the 478B, so I think they are compatibles and that is just another name for the same socket, but I am not sure about it. On the other hand, the Intel specifications say that T7100 can work on PBG479 or PPGA478 sockets, and I don't know what sockets are that, I have only read things about socket P, socket M... Do you know any documentation to understand this sockets denomination?

Hi Dudo22,

Thank you for your quick response.

I did some research on this issue and got some useful information. The socket has 478 pin holes arranged as 26 x 26 grid with 14 x 14 section removed from the center of the grid. The socket has 2 pin holes at one corner plugged. Socket dimensions are 3.6 cm x 4.4 cm or 1.42" x 1.73" and is also known as a 478-pin Micro FCPGA or μFCPGA-478. Socket P has 478 pins, but is not electrically pin-compatible with Socket M or Socket 478 It doesn't have a lever that locks the CPU in the socket, or releases it. Instead, the socket has a special actuator that needs to be turned by about half-turn to lock or release the processor. 

If you are purchasing the same part# (for motherboard), you can install Core 2 Duo processor on the motherboard. For more information on the processors and which type of sockets they support, you can refer to the link: http://bit.ly/SQU7Bj . I am sure it will be of great help to you. 

Please reply for further clarifications.
