Greetings, all, and in case we don't chat again in the interim, Happy
Thanksgiving (and belated Happy Thanksgiving to our Canadian friends)...

Several of you are aware of the issues I've had with my wife's T61
recently, specifically, the failure of her video about one month out of
the 3-year factory warranty (nice).

This is a known issue on T61's (and other notebooks with the Nvidia
Quadro GPU), as apparently over time, the constant heat up/cool down
leads to some minute cold solder joints on the GPU connection to the
system board. While I'd read about this problem (after the fact), I was
pretty much convinced that I had five options:

1. Purchase a new system board from IBM/Lenovo, and my channel price
on the part is about $600 (this is a higher end T61 - how lovely);
2. Attempt to purchase post-warranty coverage (I believe this is
called "Service Plus" or some such), for about $150-$200/yr,
hoping that that would cover this repair;
3. Pay IBM/Lenovo for the repair outside of warranty (ouch!);
4. Find a used T61 of the same model on eBay, and perhaps swap parts
back and forth to make a single "working" machine (of course,
*all* T61's with this chip are getting to be about this vintage,
so finding one *without* this issue - unless previously addressed
- is nigh on impossible); or
5. Junking the unit.

I spied another thread in the Lenovo forums on this
just this morning, and set off to fix it myself, by baking the system
board in my toaster oven for 7 minutes at 385℉ (no kidding!) to get the
solder to reflow. Read my blog post on my experience, here:
http://www.2rosenthals.net/wordpress/?p=127/ . Suffice it to say, that
while this was indeed the wackiest repair I've ever attempted, I'm
pleased with the results. The machine is working like nothing ever
happened, and the best part is that Diane is pleased as punch. :-)


If I had seen this post less than a week ago, I might not have just ordered one for my wife.  It is a refurbished unit from IBM for about $400... funny that the cost of the whole is less than even one of the parts :/
