Upgrading Memory

[stavros24]

I currently have 4gb memory and would like to add 4gb more. The replacement sticker on the memory module says that ddr3L 1600 is compatible. I understand that the L stand for low which means that 1.35V is compatible. What troubles me is that on the actual slot there is 1.5V engraved. Does someone know which to buy?

Hi:

You need to get DDR3L.

Someone else had the same thing on a different notebook and installed the DDR3L and it worked just fine.

Here's the memory specs on the part number you posted.   Shows DDR3L.
