- Can I remove the choke? - 5 Updates
| oldschool@tubes.com: Oct 04 02:48AM -0500 I have an older laptop PC. It has a inline transformer. In other words, the transformer is between the wall plug and the PC. The little plug came off where it plugs into the PC. I have some of those plugs, but there is not enough wire between a cord choke, that is right at the end of the cord by the PC. It's molded on the wire so I cant move it. What would happen if I just remove it and put my plug on without that choke? What are those chokes for anyhow? I can understand them on video cords and so on, but why are they needed on a power cord? If I can install my plug without the choke, I will, and that will only be for a short time. I bought a new cord on ebay, but I use that computer all the time and dont want to wait till I get the ebay one. After that, the repaired one will only be a backup cord. |

The choke tries to kill EMI coming out of the computer. Cut it off, and buy a snap-on one to go over the finished cable. Clifford Heath. |

Or cut it off, then demolish the plastic molding that fixes it to the cable (revealing the ferrite core), put that on the cable before you attach the plug, and fix it in the way you like. Suggestion: use two small cable ties around the cable on each side of the core to fix it in place, then put suitable heat shrink tubing around the whole thing for better appearance. |

If you want you could also strip the ferrite ring & slip it onto the flex, or slip a different one on. NT |

The choke is to help stop the computer and switching power supplies from sending out signals that can cause reception problems with other receivers. As far as the computer goes it is not needed at all. Without it any device near by that has a receiver may not work correctly. That can include the wireless mouse and keyboard or wifi modem that is used with the computer you are using. Mostly rare cases, but can hapen. FM radios may not work well that are near by. |
