    Hey there. I don't show it on my sig, but I have a T40 that has unfortunately been gathering dust in my drawer for about a year. It suffered the infamous BGA problem with the onboard graphics card, and I ended up screwing up the motherboard while attempting a reflow repair.

    I am currently running a Dell XPS M1730; wonderful, high-powered machine, but I am thinking about repairing the T40 to use as a machine when I need something more... portable. I have found a Craigslist ad selling (used)T43 motherboards for $100. Am I correct in assuming the T43 board will work in the T40 chassis with its current components(512MB RAM, 1.6Ghz Dothan processor, a/b wireless card, etc)? Also, is the T43 also susceptible to the BGA issue as well? Any help at all would be appreciated. Thanks!

    No. T43 uses DDR2, while a T40 has DDR.

    Also, a T40 (at least originally) has a Banias, not a Dothan. There were two different groups of Dothans made, with different FSB speeds--one set for the Carmel platform, and a different set for the Sonoma platform (the T43s).

    Excellent... that was what I was needing to know. So, essentially, to use a T43 mobo in this chassis, get DDR2 RAM as well as a Dothan processor for the Sonoma platform.

    Are there any other system boards that seem to have evaded the BGA issues, or is this a platform-wide phenomenon?
