when was the first laptop invented and by whom
Laptop As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The first laptop-sized notebook computer was the Epson HX-20,[9][10] invented (patented) by Suwa Seikosha's Yukio Yokozawa in July 1980,[11] introduced at the COMDEX computer show in Las Vegas by Japanese company Seiko Epson in 1981,[12][10] and widely released in 1982.[10][13] It had an LCD screen, a rechargeable battery, and a calculator-size printer, in a 1.6 kg (3.5 lb) chassis, the size of an A4 notebook.[10] It was described as a "laptop" and "notebook" computer in its patent.[11]

Personal computer A laptop computer (also called a notebook) is similar to a desktop, but is designed for portability. Usually, all of the hardware and interfaces needed to operate a laptop, such as the graphics card, audio devices or USB ports (previously parallel and serial ports), are built into a single unit. Laptops usually have "clamshell" design, in which the keyboard and computer components are on one panel and a flat display screen on a second panel, which is hinged to the first panel. The laptop is opened for use and closed for transport. Closing the laptop also protects the screen and keyboard during transportation. Laptops have both a power cable that can be plugged in and high-capacity batteries that can power the device, enhancing its portability. Once the battery charge is depleted, it will have to be recharged through a power outlet. In the interests of saving power, weight and space, laptop graphics cards are in many cases integrated into the CPU or chipset and use system RAM, resulting in reduced graphics performance when compared to an equivalent desktop machine. For this reason, desktop computers are usually preferred over laptops for gaming purposes.
