How To Dell Inspiron 1100 Ac Adapter Power Plug
Cut the Dell Inspiron 1100 AC Adapter cord
So now we move on prepping the cords.
Generic Dell AC Adapter
1. Cut the cord to desired length. Make sure to leave enough cord length so you could actually solder it to the original laptop ac adapter cord. As for me, I left a little bit wire on the plug (one that goes to the outlet) side because I might need the Dell Inspiron 1100 AC Adapter and reuse it in the future.
2. Insert the cord in the barrel.
3. Strip the wires, exposing the wires.

So now we have come to the point of soldering the two cords.
As for me I did a little bit of checking in this step. Using a multimeter, I made sure that I am connecting the wires correctly. So here is how I did it.
1. Check your Dell Inspiron 1100 AC Adapter and it should show a diagram there what the polarity is. I’ve included a picture below showing my Dell AC Adapter‘s polarity. As illustrated in the picture, the outer conductor of the plug must be negative and the core of the plug must be positive for my case.
2. With CARE, plug in your laptop AC adapter making sure that the exposed wires are not touching. Check which wire is positive and which is negative and take note of them.
3. Now, take your generic plug and check which wire is connected to the outer conductor of plug and which is connected to inner. Make sure you take note of this.
4. Look at your notes and match which wires connect to what.
5. Start soldering the inner part of the wire.
6. Cover the first soldered connection with electrical tape.
7. Solder the last pair of wires.
8. Protect them by wrapping electrical tape on it.
Sealing the barrel
First of all before I sealed the barrel, I just added a little protection to the connections. I added zip ties on both ends of the soldered section. Reason is, in case someone pulled the cord strongly, then the zip ties will prevent the wires from disconnecting.
