Only a very small number of models have built-in power in the main unit. There is a nameplate on the power adapter, which indicates the power, input and output voltage and current quantity, etc., pay special attention to the range of input voltage. This is the so-called "travel power adapter", if the country has a voltage of only 100V . This feature is very useful. Some parallel laptops are only sold in the country of origin.

Currently mainstream notebooks use TFT ( Thin Film Transistor ) LCD . It is a screen composed of thin film transistors, each of which is driven by a thin film transistor integrated behind the pixel. There are four pixels behind each pixel on the display (one black, three RGB colors). The independent thin film transistors drive the pixels to emit colored light, which can display true color of 24 -bit color depth, and can display screen information with high speed, high brightness and high contrast.

This design allows users to enjoy the convenience and comfort of a desktop in the office, and the portability of the notebook while on the move. By extending the docking station, laptops can greatly expand their use, making them equivalent or even more than desktop. There are multiple expansion slots on the docking system, which support a variety of devices, including optical drives, hard drives, second or third batteries, etc., which can make up for the shortcomings of the thin and light notebooks carrying fewer accessories, and can choose accessories in different occasions. .
