    Hi everyone. I have a problem with the power supply of my Toshiba M305-S4820. It appears that the cord near the connector to the notebook is damaged. I have already ordered a new power supply (because this one has many other little problems) but it will take around 20 days to arrive, and I need to use my notebook earlier.

    I buy a replacement connector and I am about to change it but I have a problem.

    The damaged zone of the cord is right next to some kind of filter with I assume is related to RF interferences or something like that. I am not sure I can change the connector without having to extract this filter.

    Does anyone know the exact function of this filter? Is it safe to use the power supply without this filter? Remember, It will only be for a couple of weeks.

    I attach an image of the filter I am talking about:

    Thanks you

    The device you're referring to is an inline Ferrite Choke. They're designed to dampen interference from the cable itself from interfering with any system operations. You can probably get away with removing it if you have to until you get a new cable, but remember that its intended function is to dampen noise output from the cable from interfering with system circuits, so if you have any weird problems you'll know what to suspect first....

    The filter is usually a ferrite core which is in two halves inside that plastic housing. It absorbs free radicals along the electric line.
    If you need to splice a new connector on you can do this. Make sure to reattach the ferrite cores when you are done.
    You can simply use electrical tape to secure the filter to the wire.
    It is safe to run it for a while without the filter, but its better to have it on

    This happens every once in a while on some of my systems too.
    Since about 2005, Dell has equipped all of their laptops with impedance matching technology. So if you were to install say a lenovo or hp power supply into your dell, the system would reject the power cord. Every once in a while the impedance mapping doesn't work properly and boots on battery thinking the power adapter is wrong. Their isn't really a fix for this. But you can simply boot on battery, than plug your power adapter in as the bios boots and everything will be fine.
