Understanding Laptops
Quentin Docter, Jon Buhagiar · 2019
This chapter introduces the laptop computer architecture and explains how it differs from desktop computer architecture, including specific laptop hardware technologies. Laptops are similar to desktop computers in architecture in that they contain many parts that perform similar functions. However, the parts that make up a laptop are completely different from those in desktop computers. The obvious major difference is size; laptops are space challenged. Another primary concern is heat. Restricted space means less airflow, meaning parts can heat up and overheat faster. The primary differences between a laptop motherboard and a desktop motherboard are the lack of standards and the much smaller form factor. As mentioned earlier, most motherboards are designed along with the laptop case so that all the components will fit inside. Therefore, the motherboard is nearly always proprietary, and that's what we mean by “lack of standards.” They use the technologies you're used to, such as USB and Wi-Fi, but it's very unlikely that you're going to be able to swap a motherboard from one laptop to another, even if both laptops are from the same manufacturer.
