All,
Here is the update you are looking for:
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.
Here is the link to the Official Technical Tip which includes the revised part number.
A sincere thanks to members of our online communities for their patience and support in working closely with us to resolve these symptoms.
