A laptop is​ a​ personal computer which is​ portable .​
It may also be known as​ a​ notebook .​
The typical laptop will range in​ weight from 1 to​ 3 kilograms,​ and will generally have an​ internal battery as​ well as​ a​ power adapter .​
While most laptops are portable,​ few can currently match the​ power of​ the​ most expensive desktops,​ though this will likely change as​ technology continues to​ advance .​
The word laptop was first introduced in​ 1983,​ and was used to​ refer to​ the​ Gavilan SC.
Despite the​ name,​ most laptops should not be placed in​ your lap if​ it​ is​ not covered,​ because they can get hot,​ and can even burn skin that is​ held against it​ for extended periods of​ time .​
The typical laptop can be powered by one battery,​ and the​ power adapter can power the​ battery when it​ is​ plugged into a​ wall outlet .​
a​ laptop can perform many of​ the​ same tasks as​ a​ PC,​ but they tend to​ be limited .​
They will have the​ same internal devices which are seen in​ desktops,​ but they will be much smaller in​ size .​
Most laptops will have a​ screen which uses a​ liquid crystal display.
Most manufacturers have designed their laptops to​ work with a​ keyboard and mouse,​ and they will also have a​ touch pad that can be used to​ move around the​ cursor on​ the​ screen .​
Laptops come in​ three varieties,​ and these are based on​ the​ size .​
An ultraportable laptop will generally weigh less than 1.7 kilograms,​ while a​ thin and light laptop will weigh up to​ 2.8 kilograms,​ and a​ medium sized laptop will weigh up to​ 3.5 kilograms .​
The idea for the​ laptop existed prior to​ the​ invention of​ the​ personal computer,​ and was first conceived during the​ 1970s .​
The very first laptop was the​ Osborne 1,​ and it​ was released in​ 1981.
While the​ Osborne 1 was massive in​ comparison to​ contemporary laptops,​ it​ was revolutionary for its time,​ because it​ allowed people to​ carry their data with them,​ and the​ computer didn't have to​ be left in​ a​ single location .​
However,​ the​ Osborne 1 was so large that it​ was not possible to​ run it​ on​ a​ battery .​
Most laptops today now use lithium ion batteries .​
While laptops have a​ few advantages over their desktop counterparts,​ they have some disadvantages as​ well .​
Unlike desktops,​ they are limited in​ their ability to​ be upgraded .​
As of​ this writing,​ their is​ no form factor for laptops,​ and the​ costs and technical issues involved with making them easy to​ upgrade aren't feasible.
The only parts of​ most laptops that can easily be upgraded are the​ hard drive and RAM .​
In addition to​ this,​ laptops are expensive to​ repair if​ they are damaged,​ and they are also easy to​ steal due to​ their small size .​
Stolen laptops are a​ common cause for identity theft .​
While the​ use of​ the​ USB port has allowed laptops to​ be upgraded to​ some degree,​ it​ will typically reduce their portability .​
Historically,​ the​ performance of​ laptops has always been low when they were compared to​ desktops in​ the​ same price range.
