A 2-in-1 laptop, also known as 2-in-1 PC, 2-in-1 tablet, laplet, tabtop, laptop tablet, or simply 2-in-1, is a portable computer that has features of both and .

2-in-1 PCs consist of portable computer components within light and thin chassis, and exemplify technological convergence. They are convenient for media consumption and non-intensive tasks in tablet mode yet useful for in laptop mode.


Terminology
Before the emergence of 2-in-1s and their denomination as such, technology journalists used the words convertible and hybrid to denominate pre-2-in-1 portable computers: Convertible typically denominated those that featured a mechanism to conceal the physical keyboard by sliding or rotating it behind the chassis, and hybrid those that featured a , complementary, physical keyboard. Both pre-2-in-1 convertibles and hybrids were crossover devices that combined features of both tablets and laptops. The later 2-in-1 PCs comprise a category that is a sibling to both the pre-2-in-1 convertibles and hybrids. Models of 2-in-1 PC are each similarly categorized as either a 2-in-1 convertible or 2-in-1 detachable, respectively, and despite borrowing the terminology of the pre-2-in-1 PCs, the two species of 2-in-1 PCs are distinct from the two species of pre-2-in-1 PCs because 2-in-1 PCs have additional features of traditional laptops.


Forms

2-in-1 convertible
2-in-1 convertibles are tablets with in which the keyboard can be rotated, folded, or slid behind the display. On most devices, the hinge is at the junction of the display and the keyboard. In the , uniquely, the display sits in a spinning frame.


Netvertible
Rotational-convertible format is where in addition to the conventional hinging action, the central single hinge mechanism is also able to rotate about a central axis perpendicular to the keyboard surface, such that the laptop can be turned into a thick tablet. Most netvertibles have the option to support active (electromagnetic) stylus and/or (resistive or capacitive), some being such as Panasonic CF series. Other examples include Portege M7xx, LifeBook T series and HP EliteBook Revolve series.


2-in-1 detachable
2-in-1 detachable are devices with detachable keyboards. In most cases, the keyboard part provides few, if any, additional features (most often a , as in the ). However, the keyboards of some detachable provide additional features similar to those of a such as additional I/O-ports and supplementary batteries. For instance, the Surface Book can leverage the discrete GPU in the keyboard upon the keyboard's connection.

When connected to the keyboard, the display of the detachable can either be free-standing on the hinge or require external support, often in the form of a kickstand. Novel ways of providing external support include the bending frame and locking mechanism of the x2.

Though the keyboard is usually bundled with the purchase of a 2-in-1 detachable, it is occasionally deemed an optional accessory by manufacturers in order to minimize the starting price of a device. In such cases the 2-in-1 detachable is often displayed with its complementary keyboard in advertisements and promotional materials. This is true for all devices of the Surface and Surface Pro lines.


Bluetooth/Detachable keyboard accessories
Although not in typical laptop sizes, but due to both , and Tablet hardware is getting more powerful, some third party accessories OEM had developed a keyboard accessories which allowed either though or connection via the to the handheld device that allowed it to work like a laptop.

Operating system such as Android even show the when connected to a mouse, where as take it even further by allowing the user to modified the UI to a typical desktop mode with window which allowed desktop level multitasking, albeit with smaller screen.


Distinction from traditional tablets and laptops
2-in-1s fall in the category of hybrid or convertible tablets but are distinct in that they run a full-featured desktop operating system and have I/O ports typically found on laptops, such as and . The most prominent element is the keyboard that allows the 2-in-1 to provide the ergonomic typing experience of a laptop.

While 2-in-1s fall in a category distinct from laptops, they loosely parallel the traits of the device category, having light and thin chassis, , and long battery lives. They are distinguished from traditional Ultrabooks by the inclusion of a display and a concealable or detachable keyboard.


Examples
The earliest device that can be considered a 2-in-1 detachable is the from 1993. It came with Windows 3.1 and Windows for Pen Computing, and had a cabled detachable keyboard, and battery powered stylus. In June 1994, IBM introduced the ThinkPad 360P, which features a display that can be rotated backwards and closed down into a pen-operated tablet.

Mainstream attention for 2-in-1 PCs was not achieved until nearly two decades later, when many manufactures showed devices, at that time referred to as "hybrid" devices, at CES 2011. While , Acer and HP all had Microsoft Windows based 2-in-1s by 2011, released the well reviewed Windows 2-in-1: The X220 Tablet variant of the X220, successor of 2010's ThinkPad X201 Tablet. The 12-inch device included a digital stylus housed within the chassis, somewhat ruggedized construction, and a multi-touch screen with a twist and fold hinge.

started its own line of 2-in-1s with the introduction of the series, the first of which was released in February 2013. It had a 10.6-inch (27 cm) display, i5 CPU, and included the Pro Pen stylus and a detachable keyboard that doubled as a protective screen cover. In 2015 Microsoft introduced the series, which, similar to the Surface Pro series, features a detachable keyboard cover and Surface Pen stylus.

Samsung entered the 2-in-1 PC market with the release of the Windows-based Samsung Galaxy TabPro S, which was released in March 2016. It had a 12-inch display, Intel Core m3 CPU, a first-party keyboard attachment, and a TabPro Pen. Its successor, the Galaxy Book, was released in February 2017. Coming in a 10.6-inch model and a 12-inch model, the Galaxy Book has an improved detachable keyboard and include an .

Since 2012, a number of other prominent laptop manufacturers, such as , , and have also begun releasing their own 2-in-1s.

While the has optional Smart Keyboard and accessories, Apple has yet to release a true 2-in-1 PC in a detachable form-factor and with a similar desktop OS, citing the quote below.


Criticism
In April 2012 Apple's CEO , answering to the question of the researcher Anthony Sacconaghi about a possible hybrid of and , compared a 2-in-1 to a combination of "a toaster and a refrigerator" that "doesn't please anyone":

2-in-1s are natively supported by the Windows, and . Various other distributions also support some touch features of 2-in-1s, though they are generally unsupported by hardware vendors.
