Question

Hi, I wanted to upgrade my ram on my new Acer aspire 5315-2153 laptop, I have been having difficulty getting the large panel on the back off. Can you give me a little direction before I break something. I remove the screws and think there must be something under the keyboard but it all seems difficult to get into. Also, I would like to know if this laptop has just 2 ram slots or if it has more? Please help if you can.

Thanks
