I am not great at electronics.... Not the pretext is done, please help I was working on my laptop and the battery ran out. I have tried to put the adaptor in but it simply is not working. I have a macbook that I bought in 2007 - so fairly old. Do you think the fuse has gone in the charger? If so, is it easy to replace? Is it anything else that could have gone wrong? If this is dead and I need a new one, do I have to find an old one from 2007 or are Apple chargers the same for all the computers? (I normally find that Apple slightly confusing when it comes to bits, parts, pieces etc!!) Many thanks in advance and please dont critique a dummy - I know some of you will think this is an easy question - but google searching has only served to properly confuse me!!
