Introduction
This guide demonstrates how to replace the RAM of your HP Pavilion TPN-C125 laptop.
Replacing the RAM on your laptop after several years is a great way to lengthen its lifespan. Upgrading the RAM to a newer, faster version will likely increase your laptop's speed and ability to handle tasks. It is important, however, to make sure that the replacement RAM is compatible with the device. This can usually be confirmed by checking the service manual found online. In this case, any DDR3 SODIMM should be safe to use. Otherwise, the replacement process is fairly simple. The only tool necessary for this replacement is a small Phillips head screwdriver.
Before you begin this repair, turn off your laptop and unplug the charger.
