Apple engineers are some of the most imaginative and pioneering in the technology industry. But they missed the boat on the design of my 65W Powerbook G4 adapter.
About one year after I bought my $3900 Powerbook, the power supply started to short out. Of course this event occurred after the warranty had expired. The smaller white cable coming out of the supply takes on a ton of stress through daily use. Eventually this thin cable weakened and shorted out completely. It shorted out to the point of actually sparking and melting the plastic. I’m lucky I didn’t have to sue Apple for my house burning to the ground.
When my first power supply shorted out I looked at it for a bit to see if I could fix it. But the white casing was pretty much permanent and I didn’t want to destroy it. So I ponied up the big bucks and bought a new one.
This week my 2nd adapter shorted out completely. And since my battery only lasts about 7 minutes I was dead in the water. I really didn’t want to fork out more bucks on another new supply so I decided to crack it open. I was able to fix the problem and put it back together, just like new….sort of.
First I had to crack open the casing. The supply was obviously designed to be disposable and the casing had no latches or screws holding it together. I had to hammer a thin screwdriver around the edges and eventually cracked the egg open.
The short in the cable was at the weak point where the cable goes into the casing. So I cut off about 2 inches of the cable, twisted it back together, soldered it and covered it with electrical tape. I tested it out before I put the case back together and it was good to go.
I then put the casing back together and used some gaffer’s tape to attach the casing’s shells back together. As you can see in the final pic, the case looks just like new….sort of. I didn’t want to use glue or epoxy, as I figured I’ll have to do this repair again. So I used Gaffer’s tape because it can easily come off to do the repair again.
I saved myself at least $80 this time. I only wish I would have done it the first time.
