Yes, if you have i5 or i7 processor, it definitely supports 16 GB. I have 16 GB in my L502x. You may use either DDR3 or DDR3L. I cannot recall if the i3 will support 16 GB, but you could look up your processor's specs on Intel's site. You needn't buy a big brand name such as Crucial. I recently bought a relatively unknown brand, Kuesuny, through Amazon for much less than the price of a big brand name, and I'm happy with it. I ran memory tests for a couple of days to thoroughly test the RAM when I first installed it. It performs well and saved me money. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
