Disassembling the Quaderno

1. Remove the Keyboard. The keyboard is held by a screw behind the port-door (on the right), a screw below a pop-off plastic part on the left of the keyboard, and a pop-off plastic part on the right of the keyboard. In addition, it is connected to the main unit by two cables which fit into zero-force connectors on the mainboard. My keyboard is labelled:

           MODEL:  NO TWK4716-01C
           PGS:    NO 701009-04
           SERIAL: NO 00000310
           DATE:   92.03.13
           

2. Remove the numeric keypad (including function keys) and screen. This is held by three screws at the back of the unit (behind plastic peel-off labels) and three screws inside the battery compartment. It is also connected to the mainboard by three cables which fit into zero-force connectors, and one ground cable screwed to the mainboard. Be careful when removing these, as the screen is connected to the rest of the computer by only three screws, all at the left of the unit, and screwed into a rather fragile bit of plastic. Chances are that the plastic broke a long time ago and everything will come apart at once. You can use 2 components glue to form a new thread if necessary.
3. The HDD is held by two screws at the right of the HDD. It is not soldered to the unit, but connected using a plug. One ground cable is screwed to the mainboard. My HDD is labelled:
