Introduction
The RAM is responsible for temporarily holding data, so if your Lenovo ThinkPad L390 is repeatedly crashing, having slower performance than normal, randomly restarts, and current applications keep crashing, then it might be time for you to replace the RAM.
This guide outlines the procedure for safely replacing the RAM in your Lenovo ThinkPad L390 if it is faulty, broken, or in need of an upgrade.
The RAM can be accessed by removing the bottom cover of the laptop and unclipping the RAM. The new RAM can then be installed in the same location and then secured.
Note:
- Before beginning this guide, make sure to power off your laptop completely and disconnect from any external power source.
- Some parts are small and can be easily lost, so place them in a safe place.
- Before replacing the RAM, you should remove the battery first.
