The IBM 5140 (or IBM PC Convertible) was a laptop that could be converted into a main desktop in seconds. It was the first battery-powered laptop released by IBM.

The LCD screen detaches for a colour CRT to be attached. IBM didn't sell many of these due to the fact the LCD was not backlit, and the competition was less expensive.

The IBM 5140 was available in two models, the 2 and the 22; the only difference being the 22 came with diagnostics software. IBM saw little success from this machine due to high costs, slow processor at 4.77 MHz, hard to read screen, and cumbersome size. Both models were expandable to 640KB RAM with third party upgrades.
