ABSTRACT:
A notebook computer has a collapsible keyboard in which elastomeric key switch domes on the top side of a dome sheet are horizontally shiftable under the keys to selectively underlie and support them for use, or to permit the keys to be collapsed to depressed positions to reduce the thickness of the keyboard in its storage and transport orientation. When the computer display housing lid is closed it contacts and pivotally depresses a small LCD status display structure supported on the top side of the computer base housing rearwardly of the keyboard and linked to the dome sheet in a manner such that the dome sheet is responsively shifted to collapse the keys. When the display housing lid is subsequently opened and disengaged from the LCD status display structure, the LCD status display structure is spring-returned to its original elevated position to responsively shift the dome sheet in a manner causing the elastomeric domes to again underlie and resiliently support the keys in their elevated operating positions.
