RAM is your PC's short-term memory, so it's incredibly important.
Not all notebook computers allow RAM upgrades; some have sealed bottoms or soldered memory.
To upgrade your laptop's RAM, you need to install the right kind of RAM.
The process to upgrade your laptop's RAM involves turning off your laptop, unscrewing the RAM compartment, removing the original memory sticks, inserting the new memory sticks correctly, and then checking if the laptop boots successfully.
