    The dog chewed the lead before the tip that goes into the laptop

    I am cutting out the bad bit and resoldering it together.

    Found there are 3 cores - earth sheath - voltage wire and in the middle of that, another small insulated cable

    I don't know what this bit does - is it important to join this also ?

    Thanks

    leachim, I don't know the answer to your question.
    However, I would strongly advise you to simply replace the power cable. If you make a mistake, or if your dog did damage you haven't detected, it could become a serious hazard (perhaps a fire risk or a risk of damage toward your laptop.)
    A new adapter is much cheaper than the kind of damage you'd risk causing.

    Dell power adapters have three wires which are 19 VDC (about), GROUND, and a status wire that tells the laptop there is a Dell compatible charger connected. Without all three wires connected, the laptop won't charge the battery.

    Thanks anyway

    The middle core may be something to do with a feedback system telling the laptop whether it was the correct power supply or not.
