The IBM PC Convertible (model 5140) is a laptop computer made by IBM, first sold in April 1986.[2] The Convertible was IBM's first laptop-style computer, following the luggable IBM Portable, and introduced the 3½-inch floppy disk format to the IBM product line.[3] Like modern laptops, it featured power management and the ability to run from batteries.[4]
It was replaced in 1991 by the IBM PS/2 L40 SX, and in Japan by the IBM Personal System/55note, the predecessor to the ThinkPad.[citation needed]
