battery life
Most notebooks have a three- to six-hour battery life. Several factors determine battery life: processor, battery type, display use and notebook power-savings features. Three main battery types are: nickel cadmium (NiCad) - good, nickel-metal hydride (NiMH) - better, and lithium ion (LiIon) - best.

REFURBISHED BATTERY
The batteries have special characteristics to the being of laptop off lease. It is important to know that its load not always could be equal to the one of a new battery. The battery life in these batteries is of: thirty minutes to six hours. Mobildepot guarantees the Refurbished batteries by 90 days in all his models of laptops.

INPUT DEVICE
Any device used to enter information into a computer (keyboard, mouse and other peripherals such as modems, scanners, digital cameras and graphics tablets). A keyboard is the primary text input device. (The mouse is also a primary input device but lacks the ability to easily transmit textual information). The most common pointing device for full-size computers is the mouse. For notebook computers, there are built-in trackballs, track pointers and touchpad's. The track pointer, located somewhere between the keys on the keyboard, looks like a pencil eraser and operates similarly to a joystick. A touchpad is a touch-sensitive surface at the base of the keyboard that allows the user to move the pointer by sliding a finger around on the pad.

trackball
Similar to mice, these pointing devices work by moving a ball. Though more expensive than mice, they are smaller and easier to use in cramped spaces. Many notebooks have trackballs built into their casing.

track pointer
Consists of a pressure-sensitive bump that moves the pointer around when pressure is pressed toward a certain direction. More expensive than trackballs, they are a little more difficult to use but do not require as much space.

touchpad
A touch-sensitive surface that is built into the notebook. Users move the cursor by touching the pad and sliding their finger toward a preferred direction.

MODEM A modem is a device which permits your computer to send and receive information via a regular telephone line. This kind of connection is usually called a dial-up connection When dial-up connections first began, they operated at 300 bits per second and were mostly capable only of sending and receiving text. Later, speeds of 14.4 Kbps and 28.8 Kbps became more common, as did Internet access. Today, a 56 Kbps modem is able to handle both e-mail and Internet access demands easily. However, sometimes even a 56 Kbps modem can be slowed or stopped by graphics, video or streaming audio, which is why many frequent users are moving to high-speed Internet service.

NETWORK ADAPTER Often abbreviated as NIC, an expansion board you insert into a computer so the computer can be connected to a network. Most NICs are designed for a particular type of network, protocol, and media, although some can serve multiple networks.

WIRELESS
Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing; these are also sometimes classified as wireless. Wireless technology is rapidly evolving, and is playing an increasing role in the lives of people throughout the world. In addition, ever-larger numbers of people are relying on the technology directly or indirectly.

802.11b
802.11b is an IEEE protocol for wireless networking. Introduced in 1999 and popular by 2001, it is a standard for wireless computer networking. The 802.11b protocol is based on 2.4GHz radio frequency modulation that incorporates a technology known as direct sequence spread spectrum (DSSS). It can transfer data at up to 11 million bits per second

802.11g
802.11g is a proposed wireless networking protocol that uses the same 2.4GHz radio frequencies that the popular 802.11b uses. It is almost 5-times faster. 802.11g can transfer information wirelessly at up to 54 million bits per second (mbps).

Wi-Fi
WiFi, Wi-Fi, or Wireless Fidelity adds a new dimension to computers. It allows computers to network with one another - without wire connections. Portable computers can hook-up to the Internet without wires, provided you're in a WiFi equipped zone and there are several of these zones available, with many more coming. Wires are substituted with wireless cards that use certain dedicated telecommunication frequencies similar to those used by home cordless telephones. When these devices are added to computers they can communicate with each other without using wires. Wi-Fi certification means that you will be able to connect anywhere there are other Wi-Fi CERTIFIED products whether you are at home, the office, campus, or in airports, hotels, coffee shops, parks and other public areas equipped with Wi-Fi access capabilities

Bluetooth
Bluetooth wireless technology revolutionizes the personal connectivity market by providing freedom from wired connections - enabling links between mobile computers, mobile phones, portable handheld devices, and connectivity to the Internet. Interface, synchronize, exchange? All of the above, and more. Bluetooth technology redefines the very way we experience connectivity.

USB PORTS (Universal Serial Bus)
An input/output (I/O) bus capable of data transfer at 12 mbps, with up to 127 devices connected in a daisy chain. USB devices may be hot plugged, meaning that power does not have to be turned off to connect or disconnect a peripheral.
USB ports are the most popular method of connecting external devices to computers, including mice, joysticks, and scanners. USB ports transfer data faster than serial or parallel ports. USB supports plug-and-play, which makes adding devices simple. There's also the upgrade of USB (called USB 1.1), which is USB 2.0. The new version is about 40 times faster than its predecessor and features total backward compatibility with the older interface.

FIREWIRE PORT
Known under a variety of names, this type of port provides a fast connection for digital cameras, scanners and other devices that transfer graphics with your computer. Apple Computer's trademarked name for IEEE 1394, FireWire is a high-speed, multi-platform serial bus that supports data transfer rates of up to 400 Mbps.

EXPANSION SLOTS
An opening in a computer where a circuit board can be inserted to add new capabilities to the computer. Nearly all personal computers including portables contain expansion slots for adding more memory, PCMCIA Cards, and support for special devices. The boards inserted into the expansion slots are called expansion boards, expansion cards , cards , add-ins , and add-ons.

PORTS
On computer and telecommunication devices, a port (noun) is generally a specific place for being physically connected to some other device, usually with a socket and plug of some kind. Typically, a personal computer is provided with one or more serial ports and usually one parallel port. The serial port supports sequential, one bit-at-a-time transmission to peripheral devices such as scanners and the parallel port supports multiple-bit-at-a-time transmission to devices such as printers.
Notebook computers have most of the standard ports included with a desktop computer, but fewer in quantity. All notebooks have the ability to accept devices like an external keyboard or mouse via a Parallel, Serial, PS2 or USB port. Some notebooks also come with a PCMCIA card slot for additional expansion, and may even come with a dedicated game port. Although very rare, some notebooks come with a FireWire port for the fastest data transfer capabilities. Connect almost any peripheral such as a scanner, digital camera, and printer to your notebook computer using available interface ports. Notebook ports are usually located on the back panel or the sides of the unit.

WEIGHT WITH BATTERY
Most notebook computers weigh between 6 to 8 pounds, including the rechargeable battery. Their general size is about 1-Inch High x 12-Inch Long and 9-Inch deep. Notebooks have built-in screens that are 11-Inches (diagonal) or more. A new generation of notebook computers, sub notebooks, have been designed for busy mobile users seeking to minimize weight and size. All of these weigh less than 6 pounds including the battery, and have smaller screens (11" or less measured diagonally). As you reduce size, however, you may lose certain features. The CD-ROM and floppy drives that are included with many standard size notebooks may be external (and optional) in sub notebooks.

OPERATING SYSTEM
An operating system is the powerful program on your computer which allows it to use all the other software you have. It is usually the first program to run when a computer is started up. Three major "families" of operating systems are the Windows family (which includes Windows 95, 98, NT, 2000, Me and XP), the UNIX family, and the Macintosh OS family. In general, IBM-compatible PCs can use the first two families, while Macintoshes use the third.

SOFTWARE
Software is a general term for the various kinds of programs used to operate computers and related devices. (The term hardware describes the physical aspects of computers and related devices.) Software can be thought of as the variable part of a computer and hardware the invariable part. Software is often divided into application software (programs that do work users are directly interested in) and system software (which includes operating systems and any program that supports application software)
Some general kinds of application software include:
Productivity software, which includes word processors, spreadsheets, and tools for use by most computer users ,Presentation software, Graphics software, Games software, Operating System and others.

CHASSIS COLOR
A chassis is the physical frame or structure of the product and your color. Case is very similar in meaning, but tends to connote the protective aspect of the frame rather than its structure. People tend to choose one term or the other.
