After a _LOT_ of trouble, I managed to run dbmeasure on it twice. I think I got different results than your results for the T60. But it gets more interesting. Here's what is inside a T40, and it is very likely that it is what one will find on the IBM thinkpads, and probably on the T60/Z60/Z61/X60: http://www.datasheetcatalog.org/datasheet/panasonic/SDC00047AEB.pdf I am studying it, but at first glance, providing TLV data for this will not make much sense. BTW: you can find just about anything in the thinkpads.com forums ;-) -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
