| So now we move on prepping the cords. | | | | the outer conductor of the plug must be negative |

| leave enough cord length so you could actually | | | | 2. With CARE, plug in your laptop AC adapter |
| solder it to the original laptop ac adapter cord. As | | | | making sure that the exposed wires are not |

| goes to the outlet) side because I might need the | | | | negative and take note of them. |

| 1. Check your Dell Inspiron 1100 AC Adapter and | | | | is, in case someone pulled the cord strongly, then |
| it should show a diagram there what the polarity | | | | the zip ties will prevent the wires from |
