  Thanks. I guess I was just hoping it would be an easy find and fix. The beep confirmed hope is lost 🥲

    Just so you know, as an inductor is just a small coil of copper, the resistivity might be low enough to trigger the beeping on the multimeter! So maybe it’s not dead. I’ve seen a lot of burned down inductor and trust me it looks way worse.

    If your multimeter can measure resistance in miliHoms, you should be able to measure at least ~10mR or more (that order of magnitude) Note that measuring a circuit like so is not guaranteed since there’s other stuff on a PCB that gets measured at the same time.

    Did you remove the motherboard and looked at the other side?

      Ah, I realise my wording was very confusing there. I meant: Because the inductor is NOT the problem - I don’t have any idea what the problem is - therefore the LAPTOP is dead (not the inductor)😂

    What beep?

      The beep multimeters make when in continuity mode. It is a way to test that 2 points are electrically connected with little/no resistance. If they are connected the multimeter will emit a continuous beep. If there is no beep than either the components aren’t connected or there is a resistor or something else preventing the connection. The amount is resistance required to prevent a connection (measured in ohms) tends to be possible to set on the multimeter

      Just the continuity test 😅
