Add an SSD
Adding a solid-state drive (SSD) is the single biggest hardware change you can make to speed up a laptop. It makes everything faster; booting up, shutting down and launching apps will all occur in the blink of any eye when compared to traditional hard drives. More and more laptops are coming with built-in SSDs, but not all of them do. And if your old laptop has a traditional hard drive inside, you can crack it open for a significant speed boost at a reasonable price. A 256GB SSD, which is a decent capacity for most users, can cost as little as $75.
