The power connector for my Toshiba R15 had begun to fray, so I decided that instead of just tossing it into a land fill, I would fix it up. Since I was going to have to repair it anyway, wouldn't a magnetic connector be better? I think that if I were to do it again, I would not make the dongle quite as long, but as it is, it breaks away with a sharp tug just like a macbook.
In the end, I have a very cheap repaired power cord with a lot more functionality!
Step 1: The problem...
Below is the before and after. It's not especially pretty, but I am happy with the results, and if I were to do it again, I think it would turn out better.
