PARTS OF A LAPTOP COMPUTER

 THE DIFFERENT PARTS OF A LAPTOP COMPUTER

The laptop or notebook computer has many parts that contribute to its functionality. A laptop can be broken up into two main sections, the display or LCD casing and the bottom casing or base. 
In this way, a laptop is setup somewhat similar to a desktop computer in that the LCD casing section is mainly made up of the parts that would be included in a desktop monitor and the bottom casing includes the main computer components that would be included inside the desktop computer itself. The display section or LCD casing of the laptop includes the parts necessary to make the LCD screen work. The parts included in this section are as follows:

1. SYSTEM BOARD aka MOTHERBOARD

 The system board is the main logic board in any laptop. All internal components are connected to the system board. This is one of the most expensive parts in a laptop.

2. MEMORY aka RAM

 More memory you have installed – better the performance of the laptop. Learn about different types of memory, compatibility issues and how you can replace or upgrade memory yourself. The memory is a user replaceable part.

3. HARD DRIVE

 The hard drive is the main storage of information in a laptop. All system files, personal files are stored inside the hard drive. Find the difference between SATA and IDE hard drives. Faster hard drive you have installed – faster data access you get. You can upgrade the hard drive yourself. 

4. PROCESSOR aka CPU

 The processor is the brain of your laptop. Faster CPU means faster data processing. 

5. KEYBOARD

 The keyboard is the main input device. Find out how the keyboard is connected to the motherboard and how it can be removed or replaced.

6. CD/DVD OPTICAL DRIVE

 The CD/DVD drive allows you to read/write data from/to a CD or DVD disc. Learn about the difference between drives with regular and SATA connectors. 

7. COOLING FAN

 The cooling fan is a part of the cooling module in a laptop. The fan helps to cool down the processor when the laptop is turned on. 

8. VIDEO CARD aka GRAPHICS CARD

 In most modern laptops the video card is integrated into the system board. If the video card fails you have to replace the whole motherboard. In some laptops the video card is a discrete module and can be removed or replaced separately from the motherboard.

9. AUDIO BOARD aka SOUND BOARD

 In most laptops the audio board is a part of the motherboard. If that’s the case, all audio board input/output components such as volume control, microphone jack and headphone jack are soldered directory to the motherboard. 

10. WIRELESS NETWORK CARD

 The internal wireless card helps you to connect to the Internet without running a cable. Learn about different types of internal wireless cards and how they are connected to the motherboard. 

11. CMOS BATTERY aka RTC BATTERY

 The CMOS battery provides power to the CMOS chip when the laptop is turned off or disconnected from the wall outlet. 

12. LCD SCREEN

The LCD screen is one of the most expensive parts in a laptop computer. The LCD screen mounts inside the display panel. If you accidentally cracked the screen, it has to be replaced. You cannot repair a cracked screen. 

13. SCREEN INVERTER BOARD aka FL INVERTER

 The inverter board is a power supply for the backlight lamp inside the LCD screen. When inverter fails, the LCD screen goes very dark and you barely can see any image on the screen. In most laptops the inverter board is mounted inside the display panel below the LCD screen. 

 

14. SCREEN BACKLIGHT LAMP aka CCFL TUBE

 The backlight lamp is the main source of light in the LCD screen. The backlight lamp is mounted inside the screen. When the backlight lamp fails, you have to replace the whole LCD screen. It’s possible to replace just the lamp inside the screen but it’s very hard and has to be performed by an experienced technician. 

15. SCREEN CABLE aka VIDEO CABLE

 The video cable connects the Laptop screen to motherboard. The video cable carries data signal for the LCD screen and power for the inverter board. 

16. WEB CAMERA

 Many modern laptops come with a web camera built into the display panel. The web camera is not a part of the LCD screen. The web camera is located on a separate board and can be replaced separately from the LCD. 

17. DISPLAY HINGES aka SCREEN HINGES

 The display hinges connect two main parts of any laptop – the display panel and base assembly. 

18. AC/DC POWER ADAPTER

The AC/DC power adapter converts high voltage AC power from the mains to low voltage DC power required by the laptop. 

19. MAIN BATTERY

The battery is a secondary source of power for a laptop. The battery gets charged while the laptop is plugged into the mains and keeps the laptop running when it’s unplugged from the mains.
