I've been searching on: http://rhombus-tech.net/community_ideas/laptop_15in/pcbs/
(with a slight formatting fix, may need double check...)
you want http://hands.com/~lkcl/eoma/laptop_15in then check pcb1 directory for a schematic PDF (just generated yesterday).
laptop_15in_PCB1__rev2_2.pdf
And I couldn't find what I wanted to know: are there GPIO (or anything else that can do) available on the laptop pcbs ?
there's very very little available, i had to use pretty much all of them. there's a 6-pin header which is for I2C and UART - that's all. that's the *only* spare pins. J1 in the above schematic.
I ask in the context of the keyboard ligthing LED idea we discussed earlier.
That would make some other laptop tinkering / modification ideas viable...
you could hang an I2C GPIO expander off the 6-pin port, but for god's sake don't try to power the LEDs from the VREFTTL coming off that same pin-header: take power from J4 instead.
