The history of Laptops started long back. The first commercially available portable computer was Osborne 1 in 1981, which used CP/M operating system. Although it was large and heavy compared to today's laptops with a tiny CRT monitor but it had a revolutionary impact on business and professionals as they were able to carry their data for the first time. A more enduring success in the history of Laptops was the Compaq Portable, the first product from Compaq, which was introduced in 1983. Although scarcely more portable than Osborne machines, also requiring AC power to run, it can run MS-DOS and was the first true clone of IBM. Another significant machine announced in 1981, was the Epson HX-20, a simple handheld computer.

Two other noteworthy early laptops were the Sharp PC-5000 and the Gavilan SC announced in 1983 but was fiest sold in 1984. The Gavilan was notably the first computer to be marked as a “laptop”. The year 1983 perhaps saw the launch of what was probably the biggest selling early laptop, the Kyocera Kyotronic 85, which owned moch to the earlier Epson HX-20. The machines ran on standard AA batteries. The built-in program include a BASIC interpreter, a text editor and a termonal program which were supplied by Microsoft.
Among the first commercial IBM-compatible laptops were the IBM PC Convertible, introduced in 1986 and two Toshiba models, the T1000 and T1200 introduced in 1987.
