Введение

If you need to replace or upgrade the RAM of your Lenovo ThinkPad T480 laptop, this guide will help.

The RAM or random access memory serves as temporary storage and working space for the laptop’s operating system and applications. It is much faster for reading and writing than other storage mediums such as a hard drive or an SSD. However, the data stored in RAM will disappear as soon as the RAM does not receive power, whether that is due to a power outage or a dead battery.

If your RAM is faulty, you might experience random crashes or reboots. You could also experience distorted graphics, failure to boot or repeated long beeping sounds.

If you would like to upgrade the RAM on your ThinkPad T480, you can use up to 32GB max / 2400MHz DDR4. It is dual-channel capable and has two DDR4 SO-DIMM sockets.

Prior to beginning this repair, be sure to disable the internal battery, shut down the laptop and disconnect from the external power source.
