This video will illustrate how to replace the Memory Module(s) in your ThinkPad T440, T440s, T450 or T450s laptop. This video is useful for those who are rep.

The Laptop has 2 Slots to install memory, already with 4 GB standard memory installed. For best Lenovo ThinkPad T450 Laptop performance use the maximum amount of 16 GB, fill all the slots with the max allowed memory per slot for your Laptop. What is the warranty on these memory? What if the memory is not compatible? My Thinkpad t450s has 8gb of RAM (4gb system, 4gb added). Since the t450s has one ram slot, I am considering replacing the 4gb RAM with a 12gb (8gb SODIMM) or 20gb (16gb SODIMM) chip. On Amazon, the Crucial single DDR3L 1600 MT/s (PC3L-12800) 8gb ram is $39, and 16gb is $157.


1080 Display -- Does anyone know if the 1080 display (non-touch) is made by LG or AUO or someone else? There was extensive discussion about the T440s, and people got different brands and the AUO was the preferred brand.

-- The options are None, 3rd m.2 SSD slot, or Smart Card Reader. If I select the Smart Card Reader option, can I later remove the Smart Card Reader and use it as a 3rd m.2 SSD slot? Or, if I select 3rd m.2 SSD slot and later want to use it for a Smart Card Reader, can I buy a Smart Card Reader and plug it into the slot?
