多谢楼上～～
我的机子09年7月一长两短报警返港更换了43Y主板，之前一直没有拆机。今天拆机一看，M0W显卡，如图。上面也照样涂了硅脂的。解释就不解释了。lz定夺吧。
不知道为什么 贴不上图，自己记一下吧：
U803C806 0813A2

G84-950-A2

参考 shoe_120 的拆机结果后，关于T61p 仅有2种可能了。
1. 对于T61p，S厂的就是没显卡门的。A厂才有显卡门
2. 不管是什么 00A(06年生产) ,00P（07年年初生产），还是XXW（07年及以后大量生产），都存在隐患。对于T61p联想根本没拿出显卡门解决方案，外面流传的极有可能是改良gpu的00H版，在目前维修的机器中未见使用。如果是这样，个人建议T61p的朋友 小心使用，再出问题，换主板的就换主板，能出掉就出掉。根据个人情况进行相应处理。
本人已经打算再用1-2年，到时候见机处理（主要看二次显卡门的爆发率，如果不高就用到彻底坏掉）。 就算坏了也值了。 现在已经淡定了，心里不闹腾。该怎么用怎么用。

这个可能性1被否决，我的T61p昨天不幸遇难。
我的61是07年10月购入8889a57 GPU 为s厂的07年28周产品，g86-740-a200w
使用至今还没有问题
型号都没变，凭啥让人相信改进了……
哈哈 俺的也是T61P呢 07年10月拿到机 07年7月产的 没坏过 不过玩大型3D游戏经常热到很卡自动关机/重启 拿去澳门IBM维修那好几次 硬说有问题 换了块主板 上了TPfan control后改成超过80度风扇5000转运行 玩大型游戏依然长期90+度 至今没再出问题

告诉大家一个好消息。nv 是有专门适合 thinkpad T61/p 所谓的大板改进型的新显示芯片的。
特别注意的是，thinkpad的改进型芯片并没有采用和其他品牌同样的命名方式。
比如：G84-950-A2 改进型还是G84-950-A2...
请问不拆机的话，能看到显卡的生产日期等信息吗？

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...

一外国朋友42w7653更换43Y9048的经历，貌似更换过后就好了！
T61p很小强的，大多数T61p都不像T61用了一年多久挂掉，从最早的07年到2010年不过就是三年，大多数T61p就算坏掉也是2009年之后的事情了，无论是官方维修还是个人维修，新换上的显示芯片，姑且不论是否为改良版，只要维修工艺没有问题，那都没有到再次爆发显卡门的时候呢。所以T61p基本上还要等待时间的检验了。
提供联想官网论坛（lenovo community)外国网友官方保修更换主板后的拆机结果供参考：
T61：
NVIDIA
30N383 1030A2 (芯片为2010年第30周制造)
A TAIWAN
N2R857.01R
G86-741-A2
T61p:
nVIDIA
UA10B165 1041A2 （芯片为2010年第41周制造）
S TAIWAN
P3U612.M2W
G84-950-A2
显卡制造日期都是2010年的，相当靠后。联想在国外的服务真是太好了！对得起我们国人啊！

太有才了哈哈www.aiqingmei.com
:D 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。
我的T61,08年3月份购入，使用至今，一切正常，还没有见到显卡门的任何迹象。纳闷中。

证明官方维修照样坑爹，永远放弃联想这个牌子。
就目前的了解。总结一下
1.T61 某个时间开始官方维修开始有改良主板更换（换没换到就看人品了）。G86-740-A2黑胶 小编号01R或03R（俗称R版）。市场上有同样的黑胶版存在，以及第二代改良 带温控的 白胶版G86-741-A2这个大编号变了。
2.T61p 官方维修有没有更换改良主板，不清楚，估计09年维修的都没这个运气。10年以后的目前没有这方面信息。市场上有2种版本，G84-950-A2黑胶版，0945A2批量生产的（应该在09年年末才生产的，小编号最后一位为W这个除生产日期其他和以前没变化），以及第二代改良 带温控的 白胶版 大编号没变，小编号为00H，S0H（最后一位带H）
目前了解就这些信息。
推荐：T61 换白胶G86-741-A2 。T61p换白胶G86-950-A2，小编号带H。
193楼的朋友贴的 国外的 T61 01R 和T61p M2W 应该都是改良版---黑胶，看来官方维修未采用白胶的。
基本来说10年维修的换上10年的芯片的基本都可以放心了。国内国外差距确实很大。杯具
我的机子马上过保修，现在正在考虑是否换显卡，比较麻烦……
本人t61p 6458bk9，08年7月出厂，过保后，11年8月1日一长两短。西安换显卡失败（显存漏珠，bga显存后南北桥漏珠），现在等待换新主板。挂掉的显卡：u7031714 0712A2 s TAIWAN P21215.M1P,主板fru：44c3930.换全新主板（至少没修过，从蓝快走后门）1500元
今天换的主板：42X7212，2010年4月8日生产。显卡：U7118394 0745A2 S TAIWAN P33560.M1W。主板看了，全新的。带fru标的。ThinkVantage Toolbox显示主板6457AK7。貌似比我挂掉的6458BK9要老一些。但是是新生产的。很诡异。
我是T61 15.4宽的拆下来看什么编号
代号G86M修订A2能说明什么
联想，CTMD。国外的 T61 01R 和T61p M2W 应该都是改良版---黑胶，看来官方维修未采用白胶的。
基本来说10年维修的换上10年的芯片的基本都可以放心了。国内国外差距确实很大。杯具
这贴子真是经久不衰，我也说说我的T61P，6470-CT0 主板是44C3931，显卡是02C178 0808A2 S TAIWAN P42383 M3W G84-950-A2目前运行正常

官方能出个结论就不用在这瞎猜了。
弱弱问一下，为什么大家都是返港返修的呢？难道全都是港行？没美行、新行、港行、日行之类的？
原装出厂机，T400出厂前，最后一批次出厂的宽屏T61机型已是改良芯片。但这机器市面上不多。大多数都存在显卡门隐患。
我的T61p被挂了，一长两短，，悲摧。我该怎么办？
