1)
The connector on the top of the LCD, under a rubber cover.
Once I saw a bluetooth adapter tha would fit there, but only once and it was 4 times as expensive as a USB one....
Is it a serial port ? usb ? or some kind of IBM's invention ?
What can i use it for ?
2)
Another questions are:
What does the "thinkpad" button do in T23 ?
3)
What could be connected near HDD bay ?
Maybe a card reader ?
In front of the latop there is a cover and on the mobo there is a 2 pin connector there.
