Let’s start with the big question. And while we hate to be the bearer of bad news, in most cases, you can’t upgrade your laptop processor. There are some laptops with interchangeable processors, but these machines are expensive and difficult to find.
Most processors are soldered right into the motherboard, presenting a challenge to the typical user, as you’ll need to remove the CPU and swap it out for a new one. If the processor is changeable, then you’ll need to make sure it fits in the same socket and that the motherboard can interact with the new CPU once it’s installed.
If you have an HP desktop computer, the product specification page will be able to tell you which processors are compatible with your existing network. While this doesn’t answer the laptop question, long story short, processing power is more or less locked in…permanently.
