What did I screw up and can I live w/o it?

When I did the reflow trick on my T40, I had some difficulty getting all the bits back together. In fact in trying to get the motherboard to sit right at the back within the potmetal brace(?), I pushed too hard and stapped off a small connector just to the right of the center at the back. It's white, four "whiskers" leading into it. Bad night, I was tired and clumsy.

What did I screw up?

If it's the modem connector, I can certainly live w/o it and would then put the whole thing back together and see if the reflow worked. If it's not and is something useful, then I need to get a new base or mb.

Thanks for your help.

I always assumed that the cable only affected the modem, but I looked closer and now I don't think so. I don't have a schematic, but my guess is that it will affect the wired LAN connection. There are 3 connectors along the cable. All 4 are present at the middle connector (near the modem and ethernet ports. 2 wires go to the modem, and 2 wires go to the connector you broke. I would expect the wires to be the transmit and receive lines for the 2 ports. If you reassemble it, please post back. I always am looking for info like this that actually comes from testing, rather than from my looking at the board with a magnifier. I don't have a machine apart right now that I could test with.

I have it in front of me now.

The connector in question is almost at the end of a dark brown plastic film, just off centerline at the back of the system board. The film is indented for it. a "4" is at top left of the connector and "J26" is at the right bottom corner.

If I reassemble it I will post what works and what doesn't, but I'd rather not if it turns out I need a new base unit/mb anyway.

That's the connector I was talking about. You know, you could take apart the plug and solder the wires to the MB where the connector is broken.

Could, but I'd have to know which direction to orient the wires so not to reverse them. Anybody?

Only the 2 middle connectors are used. If you sit with the wireless slot close to you, the red wire goes on the left.
