If your Lenovo T420 is running slowly, complaining about memory usage or does not boot up correctly, the problem may be related to a faulty memory module. This guide will show you how to replace both memory modules in your system. Note: If you need to access the factory memory module, the keyboard has to be removed. This is not the Lenovo Thinkpad T420. You can Tell by the RAM memory Slot Cover and the Position the RAM is put into its slot. The T420 RAM is Vertical Compared with being Horizontal in this Picture. That includes the cover also. Then the Battery Slot is a Dead Giveaway clue. 2019 UPDATE: Recommended 2.5' SATA III SSD: are the upgrades I made to my Lenovo Thinkpad T420. I'm sure this voids the warranty. ThinkPad T420 Maximum RAM? I'm looking to upgrade the pre-installed 4 gigs of RAM. But, on the kingston RAM website, the max RAM is 16 gigs.

Issues

The Optimus models, will not power off the NVidia GPU even if you are only using the integrated Intel GPU. To power it off, and make the machine run cooler, and much longer on battery you need to manually disable it. See how in Switchable Graphics.
