ABSTRACT:
A portable computer system which includes a modified C-7 power cord socket, which can receive either an AC power cord with a standard C-7 connector or a DC power cord with a modified C-7 connector. (However, the modified C-7 connector cannot be inserted into a standard C-7 socket.) Microswitches in the modified power cord socket detect the presence of the DC connector, and automatically adjust the power conversion circuit accordingly.
