So, a week after being delcared a write off, my iBook started working again yesterday.
I switched it on yesterday morning just like old times, as if the previous week had never happened.
This is good news. I am still going to try to send it in for repair under the iBook logic board recall, because there is clearly something very wrong with it. But now I will have the chance to back-up all my precious files before the machine is out of my hands. I'm afraid of turning my iBook off now, in case its spirit leaves for good, so I guess I'll be leaving it in sleep mode for a few days. Is that safe?
I am very pleased indeed that I may not have to spend $1250 that I don't have. Although I'd love it if Apple were to replace this machine with the latest iBook, I'd be fine with a repair, too. As for the iPod, it seems to have had a serious harddrive malfunction. I'll see if I can swap it for one of the newer models with the better battery and the funkier turquoise case!
