Most laptops should last three to five years with proper care before advances in technology start to dramatically impact performance and parts start to degrade or break. Generally speaking, high-end devices with advanced “futureproof” specs will perform reasonably well for longer compared to a budget device. It also depends on how you use it: If you occasionally browse the web on your laptop, it should work well enough for longer than something you frequently carry around and push to its limit.  At the very least, laptop batteries degrade steadily, though they can often be replaced at a repair shop.
