desktop replacement ( DTR ) is a personal computer that provides the full capabilities of a desktop computer while still moving. They are often larger, bulkier laptops or in some cases 2-in-1 PCs with form factor and interface like tablets. Due to its increasing size, this computer class typically includes stronger components and larger screens than those commonly used on smaller portable computers and can have relatively limited battery capacity (or none at all). Some use a limited range of desktop components to provide better performance at the expense of battery life. This is sometimes called table notes , portmanteau of the word "desktop" and "notebook", although this term is also applied to desktop replacement computers in general.

Origins
The desktop replacement pioneer was a portable computer from the early to mid-1980s, such as the CCMC R2E Portal, Osborne I, Kaypro II, Compaq Portable and Commodore Executive 64 (SX-64) computers. These computers contain CPUs, displays, floppy disk drives and power supplies all in one suitcase like a single bag. Similar to performance with desktop computers of that era, they were easily transported and came with an attached keyboard that was duplicated as a protective cover when not in use. They can be used wherever space and electrical outlets are available, as they do not have batteries.
The development of the laptop form factor provides a new impetus for the development of portable computers. Many early laptops have limited features for portability purposes, requiring accessories that limit mobility such as an external floppy drive or a clip-on trackball pointer device. One of the first laptops that can be used as a standalone computer is EUROCOM 2100 based on Intel 8088 CPU architecture, it duplicates desktop model functionality without the need for an external docking station.
The development of modern desktop replacement computers comes with the realization that many laptops are used in semi-permanent locations, often staying connected to external resources at all times. This suggests that there is a market for laptop-style computers that will take advantage of reduced user requirements for portability, allowing for higher performance components, greater improvements, and higher quality displays. Desktop replacement computers are also often used with port replicators, to fully enjoy the convenience of the desktop.

Design features
Modern desktop replacements generally perform better than traditional laptop-style computers because their size allows for the inclusion of stronger components. Larger bodies mean more efficient heat dissipation, allowing manufacturers to use components that are otherwise overheated during normal use. Furthermore, its ever larger size allows for easier expandability and features, as well as larger and brighter displays. However, these advantages generally come with a premium price, with many computers in this class for two desktop computers with the same specifications.
Using the laptop form factor, however, desktop replacements still often experience limitations similar to more mobile laptops. They usually do not have the ability to accept standard PCIe expansion cards, somewhat limiting their expansion capabilities. While desktop replacements can offer better cooling than other laptops, they rarely throw away heat efficiently enough to allow upscale desktop class components, and thus may not achieve the same level of performance as desktop computers.
Desktop replacement computers, with some exceptions, are difficult to upgrade compared to desktop computers, with many of their main components (such as screens) integral to machine design, and others (such as CPUs and GPUs) often become difficult to access and replace. Small desktop replacement segments do not include batteries as standard features, while some do not include ExpressCard support. They have the same limitations on serviceability as laptops, and rarely can use identical components to desktop computers.
