I have an old 17" Mac Book Pro (A1229) from 2007 that I occasionally use (like 3 or 4 times a month). The UK AC Adaptor and battery have both stopped working. I went on eBay UK to find a replacement, but they no longer have official replacements for this machine. What's a good third party brand to buy which won't damage the system? I need it to be one sold in the UK. Also, I only replaced the AC Adaptor and battery 3 years ago. Is it normal for them to die that quickly? Like I said, I only use it 3 or 4 times a month for around 30 minutes each time, so I wouldn't have thought that little usage would have been an issue. The original one that came with the machine lasted for 10 years (and that was back when I was using the system full time). I wonder if I might have got fakes (although they look identical to the originals) Thanks for any help!
