This article explains how long laptops last on average. It also discusses how upgrading components can affect the life cycle of a laptop. In general, laptops can last for many years if you invest in reliable machines and take good care of them.

It's relatively common to upgrade or replace a laptop between five and ten years after purchase, but there is no specific shelf life for a laptop.

If a major part fails and the warranty has expired, it can sometimes be more expensive to repair it than to replace it.

Outside of something breaking, the biggest reason to replace a laptop is usually speed. Depending on how powerful your laptop is when you buy it, you may find that the applications you want to run on it no longer run smoothly.
