Dell D630 died after MOBO replacement - strange behavior

[tankman1989]

**I tried to boot the machine again but this time I put the DVD drive in and it booted. I didn't think this would matter but I guess it does/might.


I have a Latitude D630 that had a very strange video problem. The screen was displaying double output split horizontally. It must have been dropping lines to make all of it fit because I could read the text and see everything fairly well. Everything else worked fine though. It worked fine, closed the lid & came back an hour later and it was like this. It has an nVidia chipset which I've heard has this type or similar problems.

So I get a used MOBO for a 620 from a local shop. Owner says it will fit and work fine. Only differences is it has an Intel video chipset and no firewire port. I swap the MB's & the heatsink doesn't seem to contact the video chip very well but it doesn't look like it needs it - thick thermal paste on all 3 chips. On boot I get a dark green screen where the black is - the blue "DELL" logo is fine. I enter BIOS and everything shows up as working but color is slightly off. Oh, the text was hard to read prior to getting into BIOS as it was a little light - looking at the screen from a very steep vertical angel made the LCD look black and normal (so looking from the top down).

I start to smell electric heat so I turn it off ASAP. I'm thinking that the MB is bad since the screen was green from the first second of boot and then the smell.

So I put my MB back in and try to boot and nothing. Took the MB out, checked & put it back in & checked all the cables about 6 times making sure they were hooked up and the same thing. reseated RAM, swapped RAM, nothing. The RAM didn't smell and I tried sniffing the bad/hot MB and could locate the source of the hot electric smell.

Now I'm stumped. What could the used MB have fried that would make this laptop stop working at all? Nothing was changed and it was working fine before trying the used MB. I'm stumped.

Does this sound like a bad used MB to you guys? The LCD is new, RAM is new, battery is new.

I read your post three times and laughed every time.

This can't be a real, are you trying to be funny ?

ps- why do you post so many threads asking for help ?
