In this episode, we focus on internal laptop components, beginning with one of the most commonly serviced parts—batteries. We explain the various types of laptop batteries, how to identify compatibility, and what to expect when replacing or servicing them under warranty or in a field environment. Then we dive into laptop keyboards and touchpads, breaking down how these integrated input devices are removed, replaced, and tested. Lastly, we explore RAM installation in laptops, including how S O D I M M modules differ from desktop memory and how to properly upgrade RAM in tight form factors.

This episode helps you develop a practical mindset for mobile device servicing and makes it easier to visualize how laptop internals are laid out. These topics often appear in exam questions that combine hardware identification with troubleshooting scenarios, so we place strong emphasis on terminology and configuration standards. Whether you’re reviewing or encountering these for the first time, the clear structure of this lesson helps reinforce retention and improves your readiness for performance-based items.
