终于找到原因了
差不多过了快半年了，lenovo终于找到原因了，效率还是满高地**\ ：
昨天才在官网上发布的，解决方法是换主板,FRU 42W7877 换为 FRU 44C3931：

T61p may lock up when playing games or running video benchmarking software, or may report an "nvlddmkm.exe" error - Thinkpad T61p (type 6457, 6458, 6459, 6460, 6461, 6462, 6470)
Symptom
T61p with Nvidia Quadro FX 570M (NVIDIA NB8P-GL) graphics and two memory DIMMs installed may intermittently lock up, typically when doing graphics intensive processing such as a video benchmark or video game.
T61p with Nvidia Quadro FX 570M (NVIDIA NB8P-GL) graphics and two memory DIMMs installed may intermittently report has stopped responding, but has recovered typically when doing graphics intensive processing such as a video benchmark or video game.
Affected configurations
The following systems running Microsoft Windows XP, Windows Vista may be affected:
ThinkPad T61p (type 6457, 6458, 6459, 6460, 6461, 6462, 6470)
Solution
Contact the help center and reference this tip to get your planar replaced. The substitution is FRU 42W7877 ===> FRU 44C3931
这个是官网论坛上08/4/15的解释，好像是说插上两根内存引起电压下降使得GPU供电不足？ 08/3/20后出厂的T61P更换了部件，应该没有这个问题：
Late last year, our attention was drawn to several ongoing discussion threads on Thinkpads.com and Notebookreview.com concerning lockups, crashes and blue screens experienced on some T61p Thinkpads while playing 3D intensive games. We reached out to several forum members to provide assistance with service and to evaluate their systems. Lenovo product engineering worked to recreate the symptoms while following the discussion in the forums, where members continued to collaborate , sharing the results of their own tests, and narrowing the conditions down to running 3D intensive applications with 2 memory modules populated.
Upon analysis, some T61p system boards appear to have higher sensitivity to a condition in which the power draw of the GPU in conjunction with fully loaded memory bus creates a voltage drop condition, which in turn produces the noted symptoms. To resolve, engineering has revised the value of a discrete component to enhance voltage stability.
This update is included for all new T61p systems built on or after 03/20/08 . Due to differences in usage, memory config, and board tolerances, only a portion of previously built T61p systems may ever experience this condition. Owners who have experienced these symptoms should seek service at their convenience, after working with support to rule out any other potential causal factors. |
