what memory do i need? can't figure it out

http://www.newegg.com/Product/Product.aspx?Item=N82E16834146848

i have this laptop and have no idea which memory to buy to upgrade to 8 gigs. according to lenovo this model doesn't exist. it's not listed in their online tech support guide here. thanks in advance, i'm kinda lost and already ordered the wrong thing once.

Best way is to turn it off, flip it over, open up the memory compartment and see what's in there right now. Each stick should be labeled and you just buy bigger sticks of that memory.

I usually use Crucial's website as a guide.
