How to upgrade RAM in your Lenovo ThinkPad L390
Note: Before beginning any upgrades on a PC, it's a good idea to back up your data in the unlikely event something should go wrong. You'll also want to ensure you're not working in a static-filled environment, as it can cause damage to a PC's internal hardware. Consider investing in an anti-static wristband to avoid unnecessary damage.
Lenovo ThinkPad L390 models are available from Lenovo with 4GB, 8GB, 16GB, or 32GB of RAM, and you can even choose with the first three values whether you'd like to go with a single channel or dual channel setup. No matter how much RAM you check out with, you will find two SODIMM slots easily accessible within the L390.
As an upgrade, we recommend having a look at Crucial DDR4-2400MHz RAM. It's reliable, it's priced competitively, it's available in up to 16GB sticks, and there should be no compatibility issues with your L390.
Once you have the RAM you'd like to upgrade with in hand and have made any data backups, you can power down your L390, clear out a well-lit workspace, and proceed with the steps below. Our model is using just one stick of RAM, leaving the other slot free, but the steps remain essentially the same for removing the back panel, removing old RAM, and installing new RAM no matter if you have one or no free slots.
Unscrew the nine silver fasteners on the bottom panel of the ThinkPad L390. They are designed to not completely back out to help prevent loss.
Pry up the back panel using a pry tool. Start at one corner and carefully work your way around the device.
Unclip the silver arms on either side of the RAM module by applying pressure. The RAM should pop up and remain at an angle.
Remove the RAM from the slot by carefully pulling it away.
Insert the new RAM at about a 45-degree angle. Notice it is keyed and will only fit the slot one way.
Press down on the RAM until the silver arms clip back into place, securing it in place.
Replace the bottom panel of the laptop by applying pressure until you hear it click back into place. Because the screws don't come completely away from the back panel, you might have to back them out again as you're replacing the panel to get it to sit flat.
Screw in the nine silver fasteners on the back panel.
You should now be free to power on your ThinkPad L390 to ensure the RAM upgrade went according to plan. You can check to see if it's been recognized by your system with the following steps.
- Right-click the Start button.
Click System.
You should now be able to see the total amount of installed RAM in the Device specifications section. As long as it matches the total amount you have installed, your upgrade was a success.

There's still the excellent ThinkPad keyboard, plenty of ports, upgradeable hardware, all-day battery life, and durable build available in silver or black colors. There are still two SODIMM RAM slots easily accessible after removing the back panel, allowing for future upgrades to keep your device relevant longer.
