Abstract

A method for operating an input device and a laptop computer. The input device may be attached to or detached from the laptop computer and may be accessed by a user in either the attached or detached positions. The user may secure the laptop computer in a stowed configuration without removing the input device and may access the input device immediately upon re-positioning the computer from the stowed configuration to an unstowed configuration. The user may access the input device by manipulating a joystick, touch pad or rotatable sphere. In one embodiment, the user may rotate the rotatable sphere by moving it with the fingers when the input device is attached, and by inverting the input device and moving the input device across a flat surface when the input device is detached.

11. The method of claim 10 wherein the act of transmitting a signal comprises generating the signal by activating a touch sensitive surface of the input device.

12. The method of claim 10 wherein the act of transmitting a signal comprises generating the signal by rotating a sphere of the input device.

13. The method of claim 10 wherein the act of transmitting a signal comprises generating the signal by moving a joystick of the input device.

14. The method of claim 10 wherein the signal is an infrared signal and the act of transmitting the signal further comprises emitting the infrared signal from the input device.

15. The method of claim 10 wherein the signal is a radio frequency signal and the act of transmitting the signal further comprises emitting the radio frequency signal from the input device.

16. A method for operating a detachable input device of a laptop computer, the laptop computer having a first portion and a second portion coupled to the first portion and movable relative to the first portion between a stowed position in which the computer is configured to be transported and an unstowed position in which the computer is configured to be operated, the input device being detachably attached to at least one of the first and second portions, the method comprising:

moving at least part of the second portion away from the first portion to position the second portion in the unstowed position;

accessing the input device after moving the second portion into the unstowed position and before moving the input device relative to the one of the first and second portions to which the input device is attached;

moving the second portion toward the first portion to position the second portion in the stowed position; and

securing the second portion to the input device while the input device is attached to the first portion.

17. The method of claim 16 wherein the first portion comprises a keyboard, the second portion comprises a display and is pivotably coupled to the first portion, and the act of moving at least part of the second portion comprises pivoting the at least part of the second portion away from the first portion.
