    Hello,
    Its a lot of time im following the forum, thank you for all your job guys. Anyway today i got stuck into a problem. My notebook got a little problem in its power system. I think i found the component but im not sure: i think its a tranformator. I teated it dor continuity and it beeps. I thing the insulation got a problem because of an electric shock. Can you confirm me its a transformer? The component is labeled "100 M17".

    Thank everyone in advance for help

    Hello,

    The mentioned component is likely the coil for the switched regulator on the board.

    Hello,

    Yes, A coil will measure a very low value on an ohmmeter.

    And in what way is this relevant to Test Instruments?

    If you followed the forum for some time then you should notice that there are various subcategories. This one is for topics related to test instruments.

    You should have posted in another category where your question is better suited, i.e. General Electronics.

    @Mods, can you please move this thread?
