Thin-and-lights

Medium-sized laptops
These usually have screens of 15 – 15.4 inches diagonally and a weight of around 3-3.5kg. They usually sacrifice a little computing power for smaller dimensions and longer battery life,although the length and width are usually determined by the screen size.
Desktop replacement computers
Powerful laptops meant to be mainly used in a fixed location and infrequently carried out due to their weight and size; the latter provides more space for powerful components and a big screen,usually measuring 15 inches or more. Desktop replacements tend to have limited battery life,rarely exceeding three hours,because the hardware is not optimized for efficient power usage.
