The table above lists some of the top selling Thinkpad T480 models in the U.S. You can see most are equipped with 8GB of RAM, so upgrading to a total of 16GB of RAM is pretty affordable and easy to do yourself. I’m pretty impressed with the standard PCIe NVMe SSD drives that come with most of these models. The SSD can also be easily upgraded following the same steps above if you find you need more storage space.

Verify The Amount Of RAM You Have?

If you need to double check just how much memory your T480 has, you can simply look in Windows 10.

In Windows 10:

  1. Right click the Start Menu and select System.
  2. In the System section, next to Installed RAM, you will see the amount of memory your system has.

Alternatively, you can enter the T480 BIOS by powering on the laptop and pressing F1. This enters the machine BIOS that displays the memory amount.

How Much RAM Do You Need?

The amount of RAM you may need depends greatly on how you use your laptop. 4GB might be enough for a casual user mostly web browsing.
–> Read my related article: Laptop Buying Guide, How To Choose. It goes into detail about what to look for in a laptop and how much memory you may need.

For most casual users 8GB of RAM is sufficient. For heavy users or gamers, 16GB or more might be preferred. You can accomplish a majority of tasks and open spreadsheets, play some games, etc. on 8GB of RAM.  If you plan on doing heavy data intensive processes such as video editing or serious game play, you should look to 16GB of RAM.

Think about upgrading the RAM if your laptop seems slower than it used to, takes a long time to boot up, or hangs and freezes. These may be signs you are running low on memory.

In Summary

The Lenovo Thinkpad T480 RAM upgrade procedure is simple to accomplish for most users and can help with the performance of your laptop. The cost of RAM is fairly affordable if you do decide you could benefit from an upgrade.
