my girlfriend's macbook pro is fucking up and won't load up. She will push the power button and it loads the gray screen with the white apple logo, make the chime and then it will display the rotating loading icon, but that's it. We've waited for about 10 minutes for it to load, but nothing. She really never charges it fully. It'll be plugged in for a couple hours, then use it, or she will use it while it's plugged in. We left it charge overnight to see if it needed an absolute full charge, but still the same thing the next day. I tried the PRAM resetting thing that I found while searching google, but nothing happened beyond two chimes instead of one. Is this just all because of her battery or could there be something worse wrong with it? Sorry for any mumble in there, but I'm not used to Macs at all. thanks for any help!
