Help me identify the parts

Hi guys. Kind of a weird situation and I need your help. Please read on.
I usually buy broken laptops, gaming consoles, desktops, LED monitors etc refurb them and then resell them.
Recently, I came across a Sony VAIO which has been previously tampered with by other people and has been upgraded from it's basic specs.

The problem is, this laptop has an ethernet port which does not fit the motherboard.
The ethernet rj 45 jack has a m970 cable with a 8 pin connector. The motherboard, which is a M961
MP has an ethernet port with only 6 pin outlet.

When I disassembled the laptop, the ethernet port connector wasn't even connected to the board, which is obvious because it didnt fit.

I'm not sure whether whoever upgraded it changed the usb port or the motherboard itself. Probably the motherboard was changed because it was an upgrade from i3 to i5.

In any case, could anyone tell me what part I need to fix this problem?
A new ethernet port for this 961 motherboard? Does anyone know the part name or number?

Do help.

Cat5/6 ethernet...

which connects to RJ45 are 8pins. You maybe looking for an RJ11 which is 6pins. I wonder if people use that now-a-day. I haven't check but RJ11 a telephone jack?

Nope, wrong!

What you are talking about is indeed a telephone jack not an ethernet.

I am not sure any computer manufacturer ever put a telephone jack port onto a computer mainboard.

Keep in mind this is an upgraded motherboard, which means the original board and the shell of the laptop itself is older than the motherboard that it has been upgraded with.

The upgraded (newer) motherboard can't have an older tech (rj11 port)

No need for the !

I've worked on PCs before there were PCs. Way back when there were models with dialup modems so while these passed into oblivion, they did exist. Since I can't check the model number there's not much more to add here except when looking for help, offer thanks to any reply.

Off course thankfull

Don't get it in the wrong sense buddy. I am thankful for any and all replies.

The motherboard is 961_MP_MB MBX 224

But the board on this particular model was 970_MP_MB (Which I do not have right now)

Now, what could possibly different between the two boards to have a 6 pin / 8 pin difference?
Since most upgrades and replacements are done within the same family so it cant be a board from a really old time.
In my opinion either of these boards used a separate Lan board, which is very common in older Vaio series.
Right now I am not sure what to do or what to look for and any help would be welcome.

I have searched by original model number as well.
From what I have gathered the M961 motherboard was used in the PCG 61212T model. But I am not sure.
AND I have also not found a lan port / jack / lan board for that model yet. Whatever I did find, didn't match the 6 pin requirement.

So if someone could tell me which model / family the M961 board belongs to then I might be able to trace it's parts.

Then off to Sony.

You want "service manuals." However many today never deal with motherboard repair or such. Makers now just swap boards. They don't change a connector as you noted.

Already posted.

Yes, most sweat shops / local repair centers only replace the board not the connectors.

However a completely working / upgraded pieces sells for way for than a faulty one.

After a lot of research (online) I have found out that the M961 motherboard was used/shipped with the following model numbers:

PCG 61212T / 61211L - VPCEA25FB / VPCEA45FL

I am 100% confirmed that this board was definitely shipped with VPCEA45FL

Now I need the part number list for this model. Can anyone help?

I have already created a post on the Sony's forum lets see if I get any answers from there.

Best hope is

For someone in Sony with access to service manuals.
