A laptop, also called a notebook, is a small movable computer. Depending on the size, material used for manufacturing it and other factors, its weight ranges from 1 to 8 kilograms (i.e. 2 to 18 pounds).
The source of power is normally a single main battery, or an external Ac/Dc adapter is used. Apart from supplying power to the laptop, it also charges the battery. To avoid havoc in case of power failure, a 3 Volt cell is provided to run the clock and other vital law processes.

Though laptops are equally capable and suited as desktop computers, they are much more expensive than similar capability and configuration desktop computer. Size is the unique asset of a laptop. The components used in both, laptops and desktops are the same in terms of the functions they perform, but the components in laptops are miniaturized and made to sustain efficient power consumption.
Lcd (Liquid Crystal Display) is normally the technology used for the display screen. They have a built-in keyboard and a touchpad as input devices. Provision is also made for connection of external mouse, and even keyboard.
Apart from the advantages like compactness and mobility, a set of disadvantages has also been associated with laptops.
A huge whole of incompatibility is observed when it comes to standardization issues of laptops. There exist worldwide standards for form factors of the peripherals and add-in Pc cards used in a desktop computer. But no such standards are as yet enforced for form factors of laptop internals. Galvanic voltage, motherboard layouts, internal adapters used in connecting the hard disk, visual drive, Lcd cable, keyboard and floppy drive to the main board, all still face issues with standardization. These hits hard on the poor user who is uneducated in this relevant field. Apart from them, a bit of difficulty may also be faced by the repair technicians. Familiarization of separate parts and hardware that perform the same function is important.
As an outcome of the improper, or all most no standardization, the laptops suffer compatibility problems too. Most of the times, it is not potential to use one manufacturer`s components in the laptop produced by an additional one manufacturer. The reasons behind this can be guarnatee of goods stability, prolong goods lifetime, and to avoid dubious warranty issues. Some manufacturers furnish the laptops with a set of ports to let the user connect the hardware that he wants to use.
Upgradation of a laptop is an additional one issue. Due to both technical and economic reasons, it is limited. Due to the possession designs of the laptops by each manufacture, it is difficult to upgrade them and most of the times even repairing is a high-priced affair. The standard peripherals, like audio, video, Usb, 1394, Wi Fi, Bluetooth, are integrated in the motherboard. Upgrading these thus requires whether of external ports, card slots or wireless peripherals. As far as the memory units and batteries are concerned, they can generally be upgraded agreeing to the user`s needs.
Performance is an additional one issue. Ram is shared in the middle of schedule memory and graphic adapters in laptops. Because of which operation of the laptop is affected. The major concern of the designer is compactness and vigor efficiency against high performance. Generally, for the home requirement, laptops prove out to be good options for fast achievement of required performance. With new technology like dual core processors and perpendicular recording, laptops` operation is already showing a progressive graph when compared to the desktops.
Laptops can also pose condition hazards. Climatic characteristic generated by laptop can sway sterility in men. Also, laptop keyboard can lead to Rsi (Repetitive Strain Injury). Thus it is advised to place the laptop on a table or desk when working.
