ThinkPad is a line of business-oriented laptop computers and tablets, the early models of which were designed, developed and marketed by International Business Machines (IBM) starting in 1992. IBM sold its PC business, including laptops to Lenovo in 2005, and since 2007, all new ThinkPad models have been branded Lenovo instead. The Chinese manufacturer further developed the line, and is still selling new models in 2024.
The IBM PC Convertible is a laptop computer made by IBM, first sold in April 1986. 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. Like modern laptops, it featured power management and the ability to run from batteries.
The IBM ThinkPad 701 is a subnotebook in the ThinkPad line by IBM. The 701 is colloquially known as the Butterfly due to its sliding keyboard, which was designed by John Karidis. It was developed from 1993 and sold from March 1995 until later that year and priced between $1,499 and $3,299. The 701 was the most sold laptop in 1995 and has received 27 design awards. It was based on either the DX2 or the DX4 version of the Intel i486, combined with the CT-65545 graphics chip. The 701Cs version used a DSTN display, while the 701C used a TFT LCD. It was pre-installed with Windows 3.11 and for the DX4 models also with OS/2 Warp 3.0. The 701 was discontinued because the keyboard design was no longer a necessity after screen sizes increased. After its discontinuation there has been some speculation about a new notebook with a butterfly style keyboard.
Subnotebook, also called ultraportable, superportable, or mini notebook, is a type of laptop computer that is smaller and lighter than a typical notebook-sized laptop.
The history of laptops describes the efforts, begun in the 1970s, to build small, portable personal computers that combine the components, inputs, outputs and capabilities of a desktop computer in a small chassis.
