The power supply for my Tibook died a little while ago. I bought a new one as I needed it quickly. Looking at the old one, it seems the cable has been worn where it enters the case and, in fact, the new power supply seems to have been re-designed to reduce the wear at that point.
I was thinking perhaps I could open up the power supply and just cut off the wire and resolder it. However, I'm having grief opening the case, as it appears to be completely glued together. I wondered if anyone has ever opened one of these up. It would be handy to have a second psu.
Cheers,
J.
