Laptop

Jumat, 16 Januari 2009

With the speed of rocket fame as a laptop computer is really a fenomenal. Laptops are easily carried, powernya smaller and a quiet voice. However, laptops often feel more slowly and have a graphical display that can still be considered less, also in the process of power, but the shortfalls are not affecting the users.

Laptops are more expensive from the PC Desktop.
How might all the equipment that we normally find on a PC desktop as much as it can be wrapped in such a way into one package? and how the laptop may be able to work from a battery of strength? let us through.

Overall laptop and a PC (Personal Computer) desktop is very similar. They have the basic hardware (hardware) the same, the operating system software and the same. The main difference is how the components tesebut packed with concise.

Load a desktop computer motherboards, video cards, hard drives and other components included in a large box. Monitor keyboard and other periperal connect cables and wireless. Both the box that stands vertically and horizontally, need more room for additional cards, cables and air circulation.

Because of different designs, and capabilities in mobility component must have a laptop requirement:
Abridged to be in a small space.
Save energy
Heat from the smaller components on the computer desktop.

Often, this is the difference between the components to make a little more expensive, which could make prices more expensive laptop.

Processors
Microprosesor, or CPU, to work with the operating system to control to control the computer. This is the main, pro-brain acts as the computer. CPU high heat, then use a desktop computer fan for air circulation and peredam hot plate, a plate that is arranged in such a way to transfer heat from the processor. Because since laptops have far less space and have a more concise method for placing components peredam this summer, the CPU is usually:

Working on voltasi and a low clock speed, this reduces the discharge of heat and excessive but will be slightly slow processor performance. Many also run a laptop that is installed on the voltage and clock speed is higher, but still use the settings in a lower battery consumption.

Installation of the motherboard without a pin, pin socket, and require more space on the PC. Some of the laptop processors is installed directly on the motherboard without using the socket. There was also a laptop that uses a Micro-FCBGA (Flip Chip Ball Grid Array), which uses the ball as a replacement pin. This design saves space, but in this case means that the processor can not be released from the motherboard to be replaced or upgraded.

Having sleap mode or slow-down mode, the computer operating system and will work together to reduce the speed when the computer is not being used or not the processor is not doing the work. Apple G4 processor property also prioritize this to save battery power.

Some use laptop components of the desktop CPU set to work on the clock speed is lower. Although this may improve performance, but the laptop is often run with the excessive heat and segnifikan battery life.

In general, all have a laptop and a small fan reducer hot plate, pipe or heat spreader to help remove heat from the CPU. Some laptop models hi-end, to reduce the CPU heat using liquid refrigerant that was distributed in addition to hot pipes. Also, most laptop CPUs are the edge laptop. This allows the fan to move the heat out through laptop without other components.

Memory and Storage
A laptop memory influence the performance of speed laptop. some laptops have cache memory that are placed close to the processor, this allows akeses data faster. Some channels also have a larger buss, allows data to move from the processor to the motherboard with more quickly.

Laptops often use smaller memory modules to summarize space. Momory type used in laptop include:
Small Outline Dual Inline Memory Module (SODIMM)
Dual Data Rate Synchronous RAM (DDR SDRAM)
Single data rate Synchronous RAM (SDRAM) memory module laptop
Some laptops have a memory that is easy to upgrade and easy for the panel released.

Just like a desktop, laptop hard drives have internal, which is used to store the operating system, applications and data files. However, laptops usually have a few hard-disk space than the desktop PC. Hardisk a laptop, of course, is also physically smaller than the property of the PC desktop. In addition, performance on the laptop hard drives to revolve more slowly from the hard drive on the PC desktop, it is better to reduce the heat and use the battery.

Desktop space that has been enough to drive additional, such as DVD drives and CD ROM. Although the space on the laptop is very small but many use a laptop port modular design, which can be paired in the same place, it has three different goals:

Hot swappable - computer still running while doing pengantian drive.
Warm swappable - while still running a computer drive change, but the adjustment drive (the flow of data to use the processor) must be non-aktip
Cold swappable - the computer must be turned off during a transfer.

In some cases the drive port is not used for a drive, but can also be used as an extra battery.

Display and Sound
Pemproses a graphics unit (GPU) is a microprosesor handle the processing / calculations important in 3D graphics. As the processor CPU, a GPU high heat. Most laptops have built-in graphics on motherboardnya or have a graphics card designed specifically for small laptop. GPU manufacturers like ATI and Nvidia, both specific to produce GPU laptop. Laptops often share memory between the CPU and GPU, in order to save space and battery.

Many people consider that less than the laptop's performance grafisnya. Laptops have a lot of resources to the process of productivity applications and web surfing. However, the laptop must be struggling to overcome the latest 3D games. Only a few laptops specifically designed for game fans, have a more powerful GPU and additional video memory.

Most use a laptop screen LCD screen. Most people use the screen size between 12 and 17 inches, and the size of the screen affect the overall size of laptop. In addition, the laptop screen include:
Black-and-white (16 grayscale) or color (65,536 colors)
Or passive matrix aktip
Reflective or backlit

matrix screen aktip issued a sharp picture and is easier to read, backlit display and a better use for the poor light conditions.

Most laptops also have a sound card itself and the terintergrasi on the motherboard, as well as speakernya the built-in. However, very rarely has a quality laptop Soundcard and spiker as on the PC desktop. The audio fans and gamers can add the ability to add their laptop spiker external ditancapkan through the USB port or FireWire port on the laptop.

Power Supply
Laptop and desktop using the same electricity. Both have the same small battery to maintain the accuracy of the time, and in some cases is called the CMOS RAM. However, unlike desktop computers, laptop easier and can be taken with a battery operated.

Battery Nickel-Cadmium (NiCad) battery type is first used in a laptop computer, laptop and laptop-type long and sometimes still use the battery. The period of the battery charge is approximately two hours, but may be less depending on the memory effect. Gas bubbles in the platinum cells, reduce the total number of cell space available for a recharge. That can be recommended on the matter it is not recharge the battery before completely empty. The lack of a NiCad battery is charged when too long, can explode.

Battery Nickel-Metal Hydride (NiMH) is a bridge between NiCad battery and battery Lithium-Ion (LiIon) is the latest. NiMH have the charge longer than NiCad, but on the whole has a total period of active shorter.

LiIon battery is the standard for the latest laptop. The battery is lightweight and has a longer time. LiIon not rely on the memory effect, can be charged at random, and will not cause an effect in the summer when the charge is too long. LiIon batteries are much thinner than the battery-laptop battery that makes it ideal for notebook batteries are thin. LiIon battery can endure up to 950 times charge until 1200.

Many laptop using LiIon states have active period of 5 hours, but the size can be very dependent on how computers are used. Hard Drive, Disk Drive and LCD screen, all the objects using battery power. Even the use of wireless internet connections also require a battery power. Many models have a laptop power management software to extend the period of active or battery conserve battery power when the battery is running low.

Whitebooks
Many people make a PC for their own use or for customers. Home-made machine is called Whiteboxes (white box), which provides a significant portion of the market for computers. Some people also modify their computers to do, which is called "modding". but how to create or modify a laptop?

laptop or home-made modifications called white book (whitebook). Whitebook play the role of 5% in the laptop market and the number is slowly increasing. Industry has been running fairly well in mepertahankan number of laptop users. They make a laptop is quite difficult to be opened, modified and get onderdil2 laptop. Opening the chassis in the case of most laptops making factory warranty does not apply.

Make a laptop from the beginning is still quite difficult, because it is not easy to get a laptop devices. But vendors such as vendor-ASUS and ECS ease some of its customers to buy the framework - the framework laptop empty. Frame-frame is sold especially for resellers who want to make Whitebook and sell them to customers. In addition, we can modify or mengup-grade using the framework. Companies such as TechStyle business has made it.

Parts of the laptop Whitebook consists of:
Chassis
Motherboard
Optical drives
Screen display
Keyboard
Graphics Card
This means that you want to build for whitebook should explore:
Microprocessor
RAM
Wireless card

On this, there is no real standard for the form factor design (design and shape) of the laptop components. Processor designed specifically for laptop dipasaran very much, but the search in accordance with the motherboard is another story. For devices drivenya hard enough standard, and system memory SODIMM easily searchable, but for the other components still need more in the search.
