Laptop came with 16gb, but as 1 stick instead of 2 8gb sticks, so for performance you will probably have to buy another stick (no idea if this is for all their laptops), so you might have 32gb/24gb of (unnecessary) ram. Laptop works very well, the physical quality was undisturbed, and the internal battery wasn't too worn out. Replaced external battery, haven't tried the battery that came with the laptop. The only downside is that this seller is more expensive than other sites, but I think it's worth it for the ability to return the computer if unsatisfied. You may experience heat issues, and I have heard that if you change the heatsink for one from a t480 with a dedicated GPU, you can drop temperatures by like 10 celsius max (didn't try it). I used this computer for browsing (high quality youtube videos and school) and with my 72Wh (external) + 24wh battery (internal) I get at least 8 hours of battery life. But if you want to game or use the cpu intensively, don't buy this laptop. I installed cinnamon mint, results may vary on windows, and have tried minecraft w/out shaders, and it runs terribly (50 ish fps averaged even with an 1.8 fps texture pack on lunar client). Solid upgradeability though.tl;dr good for school/work, bad for gaming or cpu intensive, somewhat expensive but get good return policy. might have thermal issues even on low cpu activity
