Although 7.5hours sounds nearly fantastic to me, 5 hours should be easily 
attainable given certain adjustments. I can make my T43 draw a bit below 
14W, and with a 77Wh battery pack (9-cell, standard edition) that is 5+ 
hours on full charge. My understanding was that PCI-e draws more power 
than PCI, so a T42 should be able to hold out measurably longer.

It sounds like something is very wrong with your laptop. How much *does* 
your laptop draw with brightness on minimum, wifi off, bluetooth off, 
min mode on the gfx card, powersave governor and the CPU locked to the 
minimum frequency?
