memory card slots location in asus k55a?

I have had my ASUS K55A for several years, and over that time I have replaced or upgraded just about everything that can be upgraded. To this end, I have had the K55A stripped right down to a pile of parts that would scare most Geek Squad guys, and give them nightmares. The other 2 slots are under the cover which can be removed by removing the 2 screws and prying the cover from the back. Be careful though, you can easily snap the front tabs off. There are only 2 memory slots. Max of 8gb Ram. Front left corner. (Front Right Corner if the Laptop in flipped over to expose the bottom) However, the 1 USB 2.0 port does have a dedicated USB 2.0 SD Card reader plugged into it. Sorry for the bad news.
