I just received my 4gb RAM set from Crucial. I took the bottom piece off to see the memory slots. I checked multiple online guides including Apple's and some video tutorial. Every guide I checked said to untuck a tab and pull it to remove the memory. However, I see no tab to pull on the slot with the memory the other (empty) slot has the tab. I called Apple and they said to bring it to a store, but I dont want to have to unplug and carry everything, and I need my computer almost every day for school. Any suggestions?
