T61(14.1 WXGA+) with Nvidia Quadro 140m

My 4 year old laptop display appears garbled. The BIOS screen appears greenish. Also once my operating system has started up, it seems that alternate columns of pixels are not lit up.

 

Now my laptop has been out of warranty for 2 years but i am pretty comfortable replacing parts myself. So i can try to source parts, but i am not sure if the LCD or the GPU is at fault. External display works fine, but if my understanding is correct that does not mean that the GPU is fine as it uses different buses for the internal and external output.

 

So is it the LCD or the GPU? Is there a way to know for sure?

 

thanks.

Welcome to the forum!

 

It's the GPU.

 

Good luck with reviving the machine.

 

 

Cheers,

Re: T61(14.1 WXGA+) with Nvidia Quadro 140m

I agree, sounds like typical nVidia failure. You'll need a new system board unfortunately.

Re: T61(14.1 WXGA+) with Nvidia Quadro 140m

If you can get a board from a laptop made in august 2008 or later, that would be your best choice, otherwise I'd get one with Intel graphics.  

 

I'd offer to get you one but the cost of shipping it half way around the world could be a factor, so you'd be best to look locally.

Re: T61(14.1 WXGA+) with Nvidia Quadro 140m

Thanks for the TuuS, yeah the shipping costs, etc would make it expensive to get it shipped from US.

 

Are Intel boards compatible with 14.1" T61s that originally came with Nvidia boards? I would presume ports, etc might be different, no? Any chance you know the FRU number of a compatible Intel board?

Re: T61(14.1 WXGA+) with Nvidia Quadro 140m

[ Edited ]

 

 

 

Here is a list of some compatible boards.

 

 

 

Intel GM965

Nvidia NVS140

 

41W1487 Merom

41W1489 Merom

 

42W7866 Penryn

44C3933/42W7867 Penryn

 

 

 

 

The intel board has a different heatsink, but you can use the nVidia heatsink on intel, but cannot use the intel heatsink on nVidia. If your CPU is a Merom class (T5xxx/T7xxx) you can use either Merom or Penryn board. If it is Penryn (T8xxx/T9xxx) then you'll need a Penryn board, or a modified bios.

 

These numbers are for 14.1 widescreen systems ONLY.

 

 

You'll have no trouble installing an Intel board to replace an nVidia. Also note that there is no conclusive way to prove a board came from an 08/08 system unless you have the bottom case with label and the serial numbers match the bios numbers.

 

 

 

ps. let me know if you can't find an affordable board and I'll try to help.
