Re: [Thinkpad] Running a 750/755 keboardless

To the List.

I solved my own problem with the keyboardless 750/55's. I simply
disassembled the keyboard and removed the 2 plio-film circuits and the
Trackpoint circuit. Plugged them into the mainboard, and the resulting
keyboard is now twenty-three thousands (.023) of an inch "thick". Can
even be rolled up if one so desires (just don't break the circuits!)

Still require any TV-Tuners for the 755CD/CDV series.

Regards.
