Heart Notebook - motherboard.It is very different from that used in the desktop computer, but it is located the same components: CPU, RAM, ROM BIOS, real-time clock with battery and others. In most cases, the processor is located in the panels, as well as on the motherboard conventional computer.But the fan on it - the special design.It blows the radiator is not directly located on the processor, and a sealed hollow copper tube filled with a refrigerant.The other end of the tube is attached to a polished plate, pressed through a thermal paste or thermal pads to the processor.Branches of the tube leading to the same plates of different sizes, pressed to the chipset and the graphics card.This cooling system is very flat, as requi
red in the laptop.

video card - is also unusual.It is not perpendicular to the motherboard, and parallel to it.Instead of slots used for its connection jacks.A connector for an external monitor is not on the graphics card and the motherboard.RAM modules, access to which is provided a lid differ from those used in desktop computers is approximately half the length.They are known as SO-DIMM.Sometimes one of these modules is located underneath the keyboard, which in this case is easy to remove.The netbook can be a part of the memory is soldered to the motherboard.

Hard drive and DVD drive are located on the removable slide.After adapters are connected to the connectors on the motherboard.The design of these components is selected such that they consume a relatively small current and can easily fit into a laptop case.Little is selected and the voltage of the power.If both nodes desktop feed two voltages (5 and 12), in a laptop - only one (5).The netbooks are used and solid-state drives, and sometimes non-removable.And if the laptop has crashed hard drive of the old type that is not commercially available, the machine can be loaded from a USB drive.

battery is connected to the motherboard via a connector with contacts substantial section.Charge Controller automatically starts and stops its charging laptop switches from external to internal power supply and back.If your desktop computer integrated power supply generates the necessary voltage directly from the network, the laptop is a transformation occurs in two phases.External power supply generates a single voltage, component, depending on the type of the computer 12 (netbooks) to 19 V. The rest of the required voltages are generated from the power supply voltage or battery converters located on the motherboard.Fan units have power.

The keyboard and touchpad are connected to the motherboard loops.The keyboard controller is not present, it is located on the motherboard.The touchpad as it is, as in a conventional mouse.The screen is attached through a connector harness of thin wires, placed in a metallic fabric connected to the common wire notebook.Built-in speakers, and a bracket with control buttons and LEDs connected to conventional wires or trails too.In the auxiliary slots are placed miniature modules Bluetooth, WiFi, and sometimes - and GPS (GLONASS).To him through even more miniature coaxial connectors connected antenna.On each side of the motherboard are placed farmed out jacks for connecting external devices, volume control switches for Bluetooth and WiFi.

Nodes laptop very fragile due to miniaturization.It is enough to look at them to see why a laptop computer requires careful handling.But if any of these nodes fail, grieve not.Change them although more complicated than in a desktop computer, but also possible.
