Lenovo ThinkPad T480s RAM Replacement

RAM (short for “random access memory”) provides temporary storage for a computer. RAM enables a computer to run with optimal speed and performance. Some signs of faulty RAM include the blue screen of death, sluggish performance, or random crashes and reboots.

This laptop is equipped for a maximum memory module capacity of 24 GB. You can add one 16 GB 2400MHz DDR4 SO-DIMM. You can run a RAM diagnostic tool to see if replacement is needed.
