Repairing a Powerbook G4 45w AC Adapter



I stripped off the white plastic jacket to about another half-inch on both sides, carefully separating the ground (2) and main gray wire (1). This is important; Make sure that the ground and inner wire do not touch, or else you’ll short your adapter when you plug it in and you’ll definitely going to have to buy a new one when that happens.

This picture told me that I needed to lengthen the exposed wires more.

Also, the ground must be connected to its partner on the other end or your adapter will not work (I learned this the hard way).

Now all I have to do is to twist the two pairs together, the main gray one (1) and ground (2) in place, carefully solder them using a soldering rod (this is to ensure they stay together), and cover them up with electrical tape.

    Thanks man. This worked great. Took me only 30 minutes. Hardest part was separating the plastic adapter piece apart. After I got that, the rest was pretty easy. Thanks again.

    Hey there! Thanks for the awesome how-to. I attempted to crack my charger housing open the other night, got frustrated, and gave up. Your tutorial gave me a new motivation to get back at it, and after some cracks and snaps, some white electrical tape, and a half an hour, I now have an operational charger again.

    This is the first time I commented here and I must say you provide us genuine, and quality information for bloggers! Good job.
    p.s. You have an awesome template . Where have you got it from?

    This happened to me too, only I was stupid enough to buy a replacement, but it was another brand replacement, it cost me about $35 at MacSales.

    But I’ll try to fix it now using this method, since I still have the damaged one here!

    There’s no way that’s true, right? Apple never used to be quite that. I am veteran enough to remember the very first one that had pointer recognition AND two clicker buttons, never mind all this new stuff they have.
