t43 internal keyboard connector pinout

[Kurdt]

i need to know which pin pairs relate to which key. pdf schematics seems to be not enough to know that. in fact i need to hack 2 keys pressed: Fn key and Power key. is that some standard key encoding, and which of 10 pins are encoding bits to get the number. multimeter probing seems to be very difficult and time consuming.
// EDIT: actually i need Fn+F7 key for display switching.

I'm not sure which communication bus is used to send the keyboard scancodes related to the usage of the Fn key (there's an 8-bit bus and a 16-bit bus). Here's a table of scancodes which might help:

The power switch/key is on pin 19 (-PWRSWITCH) as described here:

do you think it is possible to get Fn+F7 signal connecting selected pins?

I don't believe it would be possible to do this easily through the keyboard port. The Fn+F7 key sequence sends a scancode back to the keyboard controller. It would be a byte or series of bytes meaning you would have to control the 8 input pins, along with whatever other signals are required.

You may be able to control the active display screen with other methods. What operating system are you using?

With Windows 7, use can use Windows+P (works the same way as Fn+F7; hold the Windows key down and press the P key). With Windows XP it gets harder as there is no built-in support for display switching. It might be possible to use a keyboard utility like AutoHotKey to send the appropriate scancode but I'd have to research that option.

winxp. i've tried AutoHotKey already. seems does not work. i detected fn key code as 163. my script goes like this
Send {vkFFsc163 down}{F7}{vkFFsc163 up}
does not work
or
sc01e::sc163 & sc041
mapping a to fn+f7 does not work either
