These mini versions of computer do not require any setting up or wires for connections to function. These laptops are cordless and consist of a charger to charge its battery when needed.

The HP laptop or any other laptop appears simple in structure from outside but complex from inside. It is composed of different components which are integrated or assembled all together to form the functioning body of the laptop. Any defect in even a single component may affect the functioning of the entire laptop. One such component important for the functioning of any laptop is its motherboard.

What is a motherboard?

The motherboard is an integrated circuit consisting of components which altogether forms a single unit due to which computer functions. The motherboard has no use on its own or outside the computer or laptop. It connects different source or peripherals of a computer from one another. It also connects the different electronic components of a computer system or laptop. Communication between the CPU and memory unit is regulated by the motherboard itself.

Components of a motherboard-

The motherboard of a laptop or any other electronic device consists of different types of parts referred to as its components which are responsible for the functioning of the device.

  • Microprocessor –

It is referred to as the brain of an electronic device, and it controls the instruction to execute a program and to run a system.

  • Computer memory –

Responsible for storing data in the form of chips, so as to use when required by the user.

  • The BIOS –

It is a software inbuilt in the motherboard that helps link interaction between the hardware and the operating system.

  • The CMOS battery –

These help in the organization of the memory based RAM chips when the device is in the power-off state.

Different other components are also present in the motherboard, but important ones are mentioned above.

Working of a motherboard

When the computer or laptop is switched on, signals are created. These signals are then transferred to different components of the motherboard which function as the main regulatory system, and it transmits signals for the two other attached devices in order to create a particular response.
