Re: Dell Latitude D630 faulty Nvidia chip

Ownership was just transferred, but the warranty is the same, so that sorts that. I'll have to call the guy back tomorrow and ask what he was talking about because he assured me that I'd be covered by the warranty still.

Oh well.

Re: Dell Latitude D630 faulty Nvidia chip

I got in contact with the seller and he agreed to replace the entire laptop at no cost to me, so the issue is resolved now. Is there any way to prevent the same issue from occurring on the Nvidia chip? I heard that updating the BIOS helped, but is that a permanent solution to the overheating issue? Or is there something else I can do?

Re: Dell Latitude D630 faulty Nvidia chip

The only permanent solution is to replace the system board with the Intel-only version.  All of these nVidia chips are defective - they will all fail in time.

Is there nothing I can do then? I was thinking of buying a cooling pad to keep the temps down if that would help.

The problem isn't heat - it's thermal cycling.   The chips used a faulty design that can't withstand normal heat-cool cycles.

Ask if they'll send a system with an Intel video chip -- usually, when you price system boards, the ones with discrete video fetch more money.  For just about anything with an nVidia chip of this family, the reverse is true.

Re: Dell Latitude D630 faulty Nvidia chip

Oh, thanks for clearing that up. I don't really want the Intel chip because of the poor 3d performance. Unless there's one with comparable performance the the Nvidia one.

Re: Dell Latitude D630 faulty Nvidia chip

I bought a used Dell D630 earlier this summer with the same issues.

Once the ownership was transferred, I was able to tap into a one year extension of the original warranty ONLY for the nVidia Quadro NVS 135M graphics card/chip - my motherboard & graphics chip were replaced under that warranty.

The laptop is working well (upgrade it to Windows 7 64-bit, 8gb RAM, and a larger hard drive). 

Although I bought a second Dell Latitude D630 as I was leaving on a trip and didn't want to be without a laptop.  Now I have two working D630s - one upstairs and one downstairs. 

I wouldn't mind selling one of them - but not until I have completed a current project (I've had to BUY a replacement computer before because the one I had quit working - neither were Dell computers.

Other than the one graphics card glitch (fixed under extended warranty) - I've had much better luck with my Dells than wtih other brands of laptop or desktop.

Re: Dell Latitude D630 faulty Nvidia chip

Hi.  Any idea what a new D630 motherboard from Dell with the NVidia chip would cost?

Thanks

Checked - they don't offer them on their store.  You'd have to contact Tech Support for a quote.

Ebay and Amazon might have the mother board listed - (checked eBay - around $60 to $80 for just a refurbished motherboard - graphics may vary).  For slightly more, you can get the bottom "half" of the laptop to attach to your top half.....then see what happens.

For $160 to $200 or so, you can get a used (some of them refurbished) D630 that works - speed of coprocessors and amount of RAM may vary.  Hard drive may or may not be present.  It might be easier to slide your existing hard drive into a "new" laptop body and enter the Microsoft activation code from its sticker.

You'd have to get one with the same operating system on the sticker.

It depends on how good you are with taking things apart and then putting them back together......I've replaced a monitor in a laptop & a cell phone, upgraded a Wi-Fi card from G to N, and added a Bluetooth card - decided that I'd rather stick to replacing just the RAM and hard drive rather than taking the computer apart quite that far again.

But when the graphics card quit - I did NOTHING as I had no idea what to do (and knew from a laptop that had gone wonky three years earlier that I cannot solder anything as I have neither the tools, the training, nor a "clean room" to work in!).
