Using two chargers with one laptop

dual-charing-jacks-thinkpad

This one’s a riot! [Nico] got a new computer and didn’t want to change the six power supply cords he had strategically placed around his home and at work. So he just added a second charging jack that accepts a different style connector.

First off the laptop is used — but it’s new to him. So cracking it open and soldering in a new jack doesn’t affect the already expired warranty. He had an unlimited supply of Dell laptop chargers available from work. They are rated 19.5V and the charger for this computer is rated 20V so he figured this should be no problem. Instead of just swapping out the old charging port he added a second where the RJ-11 connector (for a telephone modem) was located. Now he doesn’t need to waste money buying more chargers for the new-old machine.

This isn’t the first time we’ve seen someone replace a power jack. But it is the first computer we’ve seen that takes two different chargers.

Fixing that broken laptop power jack

It seems that there’s a whole range of Toshiba Satellite laptop computers that suffer from a power jack design that is prone to breaking. We see some good and some bad in this. The jack is not mounted to the circuit board, so if it gets jammed into the body like the one above it doesn’t hose the electronics. But what has happened here is the plastic brackets inside the case responsible for keeping the jack in place have failed. You won’t be able to plug in the power adapter unless you figure out a way to fix it.

We’d wager the hardest part of this repair is getting the case open. Once inside, just cut away all of the mangled support tabs to make room for the replacement jack. The one used here has a threaded cuff that makes it a snap to mount the new part to the case. Clip off the old jack and solder the wires (mind the polarity!) and you’re in business.

Anyone know why we don’t see more of the magnetic connectors (MagSafe) that the Apple laptops have? Is it a patent issue?
