Abstract
A low power-consumption keyboard with a pointing device attachable thereto and for use with the same comprises: a battery for supplying a power source voltage for the keyboard; a key matrix having a set of keys for generating a key code corresponding to a depressed key of the keys; a key function indicator for indicating a key function state corresponding to a depressed specific function key of the keys; a controller for selectively controlling the key code to be transmitted to the computer system by either wire communication or wireless communication; and a wireless transceiver for converting the key code into a wireless signal and for transmitting the wireless signal to the computer system. With this construction, the key function indicator is disabled during wireless communication and enabled during wire communication.
