Laptop Parts Identification
1. LCD SCREEN—–Display – Most modern laptops feature 12 inch (30 cm) or larger color active matrix displays with resolutions of 1024×768 pixels and above. Many current models use screens with higher resolution than typical for desktop PCs (for example, the 1440×900 resolution of a 15″ Macbook Pro can be found on 19″ widescreen desktop monitors).
2. STATUS BAR — A housing cover for on/off power button and other indicator lights.
3. KEYBOARD —- keyboard is an input device, partially modeled after the typewriter keyboard, which uses an arrangement of buttons or keys, which act as mechanical levers or electronic switches. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce actions or computer commands.
4. SYSTEM CASING—– Housing cover unit for motherboard and other system component
5. WIRELESS CARD—- Wi-fi PC cards for accessing wireless networks have an external portion containing the antenna for improved reception.
6. EXPANSION CARDS – A PC Card (formerly PCMCIA) or ExpressCard bay for expansion cards is often present on laptops to allow adding and removing functionality, even when the laptop is powered on. Some subsystems (such as Wi-Fi or a cellular modem) can be implemented as replaceable internal expansion cards, usually accessible under an access cover on the bottom of the laptop. Two popular standards for such cards are MiniPCI and its successor, the PCI Express Mini.LCD SCREEN
7. CPU HEAT SINK—-Internal CPU heat sink for removal of heat from the processor using thermal paste.
8. HARD DRIVE CADDY —-Hard drives caddy are used to secure the hard drive before installation.
9. HARD DRIVE CONNECTOR —-Internal Hard drive connector is used to connect the hard drive to the motherboard.
10. HARD DRIVE —-Hard drives are the primary storage units for your laptop. This is where your operating system and program data are stored. If you require additional storage space you can easily upgrade to a bigger hard drive capacity or add an external hard drive to your laptop. Storage size is measured in GB (gigabytes). Internal storage – Laptop Hard disks are physically smaller—2.5 inch (60 mm) or 1.8 inch (46 mm) — compared to desktop 3.5 inch (90 mm) drives.
11. BATTERY —–Current laptops utilize lithium ion batteries, with more recent models using the new lithium polymer technology. These two technologies have largely replaced the older nickel metal-hydride batteries. Typical battery life for standard laptops is two to five hours of light-duty use, but may drop to as little as one hour when doing power- intensive tasks.
12. SPEAKERS—-Laptop internal speakers for music and sound output
13. MODEM PORT—-Used for installation for modem cards for internet connections
14. DVD/CD-RW Drives—–Removable media drives – A DVD/CD reader/writer drive is typically standard. CD drives are becoming rare, while Blu-Ray is not yet common on notebooks. Many ultra portables and netbooks either move the removable media drive into the docking station or exclude it altogether.
15. MOTHERBOARD—– laptop motherboards are highly make and model specific, and do not conform to a desktop form factor. Unlike a desktop board that usually has several slots for expansion cards (3 to 7 are common), a board for a small, highly integrated laptop may have no expansion slots at all, with all the functionality implemented on the motherboard itself; the only expansion possible in this case is via an external port such as USB or a card slot such as PCMCIA. Other boards may have one or more standard, such as ExpressCard, or proprietary expansion slots. Several other functions (storage controllers, networking, sound card and external ports) are implemented on the motherboard.
16. MOTHERBOARD HOUSING UNIT—– Housing unit for motherboard and other system component
17. CPU FAN—– Internal CPU fan for cooling of the processor temperature
18. FRONT BESEL —- Housing units for the keyboard and mouse pad
19. Memory (RAM) —– SO-DIMM memory modules that are usually found in laptops are about half the size of desktop DIMMs. They may be accessible from the bottom of the laptop for ease of upgrading, or placed in locations not intended for user replacement such as between the keyboard and the motherboard.
Random Access Memory (or “RAM”) provides temporary read/write storage. It’s often referred to as “virtual memory” and is measured in MBs (megabytes) or GB (gigabytes). Generally, the more memory you have, the more programs you can run simultaneously.
20. VIDEO CABLE (Graphics cards)
Video display controller – On standard laptops the video controller is usually integrated into the chipset. This tends to limit the use of laptops for gaming and entertainment, two fields which have constantly escalating hardware demands. Higher-end laptops and desktop replacements in particular often come with dedicated graphics processors on the motherboard or as an internal expansion card. These mobile graphics processors are comparable in performance to mainstream desktop graphic accelerator boards. These allow the computer to display a certain number of colors and images. Higher quality graphics cards will often come with their own video RAM. The video RAM greatly increases the image quality of your laptop.
21. NETWORK CONNECTOR—-RJ45 Network port for connection of RJ45 network cable for network and internet connection.
