RAM is an important component of your laptop. While the amount of RAM that ships with your laptop is good for the first few years, most of us might require more computing power a couple of years later. Of course, there are multiple reasons to it such as frequent OS updates and software that demand more memory. If your laptop is running slow, there are chances that adding more RAM can fix most of these issues. In fact, upgrading RAM is economical and you can even do it at home by following these steps.
Just remember, if your laptop is under warranty, upgrading RAM or opening the laptop might void warranty, and even damage it. Do it at your risk.
