I just bought this laptop used. I have been reading about all the logic board issues and I am a wee bit spooked. Here is what I know. This computer was bought from apple direct in Nov 2001 as a "refurb" in the "about this mac" area.. no serial number displays. There is one under the keyboard and it falls into the numbers covered by that logic board replacement thing. The person I bought the computer from has never had it serviced and used it for 4 years and never had a prob. Its running Tiger and has 640 megs of ram. Battery gives me about 3 hours and it has internal airport. I am really likeing this computer I find it fast for what it is. Here is my question.. I have noticed that the battery charging icon and the volume and airport icons on the top bar at times seem distorted. as soon as I click on the desktop or whatever page I am working on this disapears.. could this be RAM related? I am not having probs watching video or with display or the backlight or anything. Should I be worried about this logic board thing? or just use it and forget about worrying if it has never been serviced and it already 5 years old. Sorry if my questions seem redundant or overtly "newb" I really like what I see so far and plan to make all future purchases Mac.. I bought this computer to learn on.. and plan to buy a newer "badder" machine in the next year..LOL Brooke P4 "switcher"
