I'm new here, but here's how I solved my dead graphics problem:
My T61p (6459-CTO, T7700, WUXGA 15.4") graphics died. The first time this happened, I took it in to an authorized IBM/Lenovo warranty repair shop. My laptop just went out of warranty, so this was an out of warranty repair.
They replaced my planar/system board FRU 42W7653 with another 42W7653, and I was happy. For about a month - then the graphics died again. I took it back to the repair shop and they spent nearly 3 months trying to find another 42W7653. They couldn't find a 42W7653, so they called me and gave me full credit for the cost of the repairs that they did towards a new machine *and* gave me my dead machine back.
So, since I hate wasting all those good parts, I went about searching the Internet for a 42W7653. None were available, but I read somewhere that a 44c3931 was a direct replacement.
I worked with one online company that verified that this was indeed a verified replacement, but they didn't have any of them in stock. I worked with another online company that said that the 44c3931 had compatibility problems with being a direct replacement to the 42W7653 and that I should contact Lenovo for the details since they (rightly so) didn't want to get mixed up with that.
So, to get those details, I called the IBM/Lenovo 800 support number (it's on their website under support, laptop/notebook support). I spoke with a great support person who told me that FRU 44c3931 was *not* the replacement for *my* T61p (I gave him my model number and serial number); however, he told me that 43Y9048 *was* the replacement for my 42W7653.
I could call IBM parts at an 800 number that the support tech gave me and order a 43Y9048, since he couldn't look up the price, but assured me that 43Y9048s were in stock.
So, off I went and called the IBM parts 800 number, verified that the 43Y9048 was the replacement for my 42W7653, and got a price. The price seemed high, so I wrote it down and went off searching the Internet for a 43Y9048.
Each time I found a 43Y9048 listed for sale, I called to verify the part was in stock and shippable. So, starting with the lowest cost place and working more expensive until I got to the IBM quoted price (if I had to go that far), and off I went. I found places listing this FRU for ~35% to over 110% the cost that IBM quoted me.
The first 4 places I called didn't have a 43Y9048 in stock, and couldn't tell me if they could even get it anymore. Finally I found one in-stock from a place I'd done business with in the past at a cost significantly cheaper than the IBM quoted price.
So, the bottom line is this: Call IBM support (don't forget to be nice to these folks, they really do have the information you seek) and ask for the replacement FRU for *your* specific build, do your due diligence in finding a trusted source at a price you can work with, then order it and get out your little screw-drivers (or find someone that can do the swap for you).
UPDATE:
The 43Y9048 arrived this afternoon, and my T61p is back up and running. The planar/system board swap took me less than 2 hours.
UPDATE:
The 43Y9048 had absolutely zero fitment issues and has had absolutely no compatibility issues thus far, so I think I can call this a big success.
UPDATE:
It's now been almost 5 months with the 43Y9048 replacement planar/system board and the system has been flawless - I have left it plugged in and on screensaver for weeks on end multiple times. I have my power options to maximum performance when plugged in so the HDD doesn't spin down, the LCD doesn't sleep, the system doesn't suspend or hibernate. This behaviour leads me to believe the replacement boards appear to have fixed the GPU problem.
On first boot, remember to go into the BIOS and set the date/time.
A word of advice to the wise if you are undertaking this. When you remove the screws from the planar/system board, use a red permanent marker to place a dot on the circuit board where the screws were. There are a lot more places to put screws than screws to remove - some of the screw holes will be filled when you attach the planar assembly to the outer case. You can match up the locations from the old planar/system board to the new planar/system board as you re-assemble.
You might also want to use one dot for the shortest screws, two dots for the next largest, three dots for the next largest, etc...

作为发起人。本人返港更换主板后的T61p再次挂掉（09年维修的，连官方都没修复）。所以T61p的改良版，维修点和市面上都很少。对于G84-950-A2的朋友，如果想BGA，最好选择10年以后的显卡芯片。我联系了上海 徐汇区的一家维修点，700元做BGA换上10年的G84-950-A2，改良的白胶封装版。2小时修复。目前也只能如此了。
