First of all is this an iBook G3? I am totally new to Apple in general other than my iPhone. So this will be my first mac. It is being offered for $100 because the screen will no longer show. The seller says he can sometimes get the screen to come on but not for longer than five minutes. Is it worth it to pick up and mess around with and try to fix? How much will it cost to fix if I take it in somewhere? Quote from seller: "The screen just shows up blank. When I turn it on the battery has a full charge and the noise works when I power it. I've got the screen to work a couple times but it wouldn't last long and go blank 5 minutes after...I'm pretty sure its a iBook G3, it has a 12" screen." Anything else I need to know?
