Can you upgrade the processor in a laptop?

While it is possible to upgrade a laptop processor, it's less straightforward than with a PC; you need to be sure the laptop motherboard has the right socket for the upgraded processor. Depending on the age of your laptop, this might be tricky. Moreover, opening the laptop often voids its warranty, mostly because you’re likely to break things permanently, so you really need to know what you're doing. Finally, it’s usually cheaper to get a new laptop than to upgrade your old one’s processor but this might depend on exactly what you’re trying to get out of the upgrade.
