Hi, I get my first macbook yesterday. Loving it! Got the White model, the first refresh of the year, just before this june refresh, buy I don't care. So, here's the deal. I gonna use this machine 80% of the time in my home, not gonna move it from the desktop. So I'm using right now without battery, connected to the macsafe. Should I keep it that way? or I need to put the battery? Because I heard that if the battery is always there and the macbook is connected to magsafe, the battery die fast. I also don't know if that I'm doing is safe for the Macbook, to say without batery. Please help. Oh! btw, when I first remove the batery, something really strage felt off the macbook, was like a tiny tiny tiny little metal, works well without it, but I want to be sure that's nothing importante. thanks for the help. Sorry my bad English, I'm from Peru.
