RAM is a vital component that helps your device run efficiently. It allows the system to open new tabs and temporarily store data.

If your device is running slowly, crashing randomly, failing to boot, showing application errors, or displaying visual glitches, the RAM is likely the cause.

This guide will show you how to replace the RAM in the Lenovo IdeaPad L340-15API.

Before you begin the repair, power off the laptop and disconnect the charging adapter and any external peripherals.

Using your fingers or a spudger, spread the clips away from the RAM module.
Be careful not to pull too hard and damage the metal arms.
When released, the RAM module will pop up at a slight angle.
Lift the RAM module to an angle of about 30 degrees and slide it out.
