I purchased a Dell Inspiron 11-3168, and I was told by Dell support themselves that it can be upgraded to 4GB of ram. I have the ram, but for the life of me I CAN NOT find where to add the sticks! There appears to be no DDR3/DDR3L sticks anywhere on the motherboard or on any other circuitry for that matter. Has anyone ever worked with this little 2-in-1's?
