In what year did the laptop debut?

Answer 1

That depends on what you define as a laptop. There is no firmly agreed definition, so choose your own.

The first self contained laptop size and weight machine that used an LCD screen was the Epson HX-20 introduced November 1981. It had 20 characters of text on each of 4 lines of display and weighed 3.5lbs.

The widest consensus agrees the Osbourne 1 introduced in April 1981 was the first "true" portable computer. It had a handle, the keyboard folded up to cover the 5" Cathode Ray Tube(CRT) screen, a battery pack was an option. However at 24.5lbs a person was not likely to use it on their lap.

Earlier, September 1975, IBM released their model 5100 considered to be the first self contained "portable" computer. It had everything needed to operate in a single unit that could be carried from place to place. The built in keyboard did not fold. There was no factory battery option. 55lbs makes laptop use even less plausible.

Early on, some machines were called "portable" if they could be moved with a forklift or hand truck and did not require being custom built within their own dedicated room where they would remain for their useful life.

Answer 2

The first commercially available portable computer was the Osborne 1 in 1981, which used the CP/M operating system. Although it was large and heavy compared to today's laptops, with a tiny 5" CRT monitor, it had a near-revolutionary impact on business, as professionals were able to take their computer and data with them for the first time. This and other "luggables" were inspired by what was probably the first portable computer, the Xerox NoteTaker. The Osborne was about the size of a portable sewing machine, and more importantly, could be carried on commercial aircraft. However, it was not possible to run the Osborne on batteries: it had to be plugged into mains.

Answer 3

September 1975 was the first available portable computer.

1981 was the first laptop-sized portable computer.

I didn't know which one you'd want to use so I just put them both.

Hope this answers your question in enough detail.
