How to Upgrade a Dell Laptop Computer
Laptops are fun and portable but they have a couple of downsides compared to desktop computer. They are typically more expensive and harder to upgrade? Why? The components that go into a laptop have to be small and more efficient because of an economy of space. This also means there is less room to add things like a second hard drive or additional memory cards. That doesn't mean you can't upgrade a Dell laptop though.

You can find drives that are compatible to your laptop by using your preferred search engine or visiting a local computer store.
