A laptop computer (also known as notebook computer) is a small mobile personal computer, usually weighing from 1 to 3 kilograms (2 to 7 pounds). Terms for subtypes of notebooks (and related computer types) include:

• Notebooks smaller than an A4 sheet of paper and weighing around 1 kg are sometimes called sub-notebooks or subnotebooks.
• Notebooks weighing around 5 kg are sometimes termed desknotes (desktop/notebook).
• Powerful laptops (often heavy) designed to compete with the computing power offered by a typical desktop are often known as desktop replacements.
• Computers larger than PDAs but smaller than notebooks are also sometimes called palmtops.

Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity.

Laptops are capable of many of the same tasks that desktop computers perform, although they are typically less powerful for the same price. Laptops contain components that are similar to those in their desktop counterparts and perform the same functions but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and use SO-DIMM (Small Outline DIMM) modules (rather than the larger DIMMs used in desktop computers)for their RAM. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external mouse or keyboard can usually be attached.
