A notebook computer with a tilting keyboard, which opens a vent when tilted, solves multiple problems and may further materially contribute to countering terrorism. A tilted position of the keyboard allows the vent to open when the notebook lid is open, thereby providing extra cooling capacity during periods of computer use when there is a lessened need for compactness. The vent is it least partially closed when the keyboard is in the stowed position and the lid is closed, thereby reducing the possibility of debris ingestion when air flow needs are reduced and the need for compactness is increased. A security inspection position of the keyboard enables inspection of the inside of the computer, for example as part of a security checkpoint procedure. A negative tilt can reduce wrist strain and repetitive motion injuries for some users. Some embodiments tilt the keyboard automatically in response to the lid opening, and stow the keyboard automatically in response to the lid being closed.
