Introdução
If your Dell Latitude 3420 is running slow, freezing during multitasking, or struggling to open programs, you may need to upgrade or replace the RAM. The RAM modules control how much data your laptop can handle at once. When they begin to get old or are too small for what you need, the performance drops fast. This repair involves removing the bottom cover, releasing the existing RAM from its slot, and installing a new module. Make sure the new RAM is seated firmly before closing the laptop again.
