yep...releasing service manuals would make them lose some customers, out of warranty people, and would infuriate some tech professionals...i've dismantled a fair amount of laptops now...desoldered some parts and put new ones because they were broken ..usually it happens with the power supply...most propietary, brand laptops are quite difficult to dissassemble (toshiba ones are the worst, and they have great service manuals, wish i could get a hold on those...i saw them from a friend who worked a repair store..). We're not helpless but to find out some tricks you just have to spend much more time and effort, that's the thing with closed devellopment, they just want us to be consumers.
(what reminds me of this Holland crew that had some fine hardware hackers, "hippies from hell"...and reminds me too of the people who hardware hack toys to produce electronic music or Noise.)
Hope you get a usefull response.(at least to fullfil your curiosity
)
