D630 expired NVidia - systemboard replacement options.

Question

Have been given a Dell Latitude D630 to sort out. It has dual images on boot screen. Vintage September 2007. I am 100% confident that this is classic NVidia failure. Dell have refused to help as NBD warranty expired last month.

So I have been looking for a new systemboard. Part number 0T795N (aka T795N) seems to be a drop-in replacement. But what is the difference to the the part number R872J discussed in this post?

Any input appreciated.

Thanks,

They're idential, spec wise - they both have the flawed nVidia chip on them. If your warranty just expired, note that there's a 12 month extension to cover the faulty nVIdia engineering:

If that's what has expired (the extension ) and you have to pay for a board, DO NOT buy another nVidia board -- most engineers believe nVidia never really fixed these GPUs, and it'll just fail again. There is an Intel video board that's much more reliable:

That link is for a D830 systemboard. Is it the same as D630?

Changing from NVidia to Intel GPU is fine with me but as I understand it the heatsink and pads have to be changed. Do we know the Dell part numbers for the heatsink and pads?

This machine is in the UK, and the customer has had no joy with getting Dell to fix it. We are sorry, happens, but tough luck your NBD warranty has expired.

What gets me is that there appears to be multiple NVidia boards available;

Pulled from scrap laptops, so likely about to expire.

NVidia boards described as Dell re-manufactured. Used board with new GPU I assume?

Brand new Dell board with NVidia. But old stock. So presumably still faulty.

Brand new Dell boards with NVidia. Vendor says revised chip.

I guess re-manufactured would be what Dell put in if they were to fix it under warranty, which they won't.

I just want to maximise the chances of it staying alive as this was an expensive laptop to start with and performance wise they are still good.

The D630 uses a different board , but the same applies - if you want a reliable system, buy the Intel version -- though nVidia claimed to have fixed the problem, many engineers have posted in multiple places that nothing short of a complete redesign - which never happened - could fix that model GPU.

Thanks, Heatsink for the board with Intel GPU= KN982 ? Fan is the same as the NVidia, I assume.
