    All of a sudden, now when I plug in my laptop at my house, the surge
    protector is triggered which causes most power points in the house to lose
    power.

    What could be the cause of this? Is it possibly due to having left the
    power cord of the laptop in a hot car?

    does it occur when you plug just the psu and not the computer in ?

    Sounds more likely to be an earth leakage trip.

    But it's only started happening now. The hot car is the only thing I can
    think of.

    did any of the power supply or lead or computer get wet?

    Nope

  8. 1. It's a Core Balance Relay or "Earth Leakage Detector" which is tripping -
    not a surge protector.

    2. Sylvia is correct in her suggestion; there's a definite path between
    Active and Earth in your cable or device, which is tripping the CBR.

    3. Plug the power cord in _without_ the power supply attached. If the CBR
    trips again, it's your power cord; if it doesn't, it's your power supply.

    4. Replacement cloverleaf power cables are $8 at Jaycar. Replacement
    aftermarket power supplies are $10-$20 including postage through eBay.
    Replacement "genuine" power supplies are around $60 from the manufacturer,
    $100 from Dick Smith or $180 from Harvey Norman.

    That’s true of all faults.
    Its possible, but unlikely.

    None of mine do.
    Ditto.

    Do as previous posters have already suggested.

    Section isolate:

    Plug the cord in.
    Does it trip?
    Plug the cord and power supply in.
    Does it trip?

    If yes, then you have isolated your problem.

    ** I take it the power cord is 3 core ?

    If so, the earth ad neutral conductors have come into contact inside.

    That with trip the ELCB instantly, every time you plug the cord into an AC
    outlet.

    The next day now everything is fine. What does that indicate? Some water
    has dried up, or something yesterday was using a lot of power in the house
    such as the air con?

    I can provide a log file proving that my computer was powered off several
    times without shutting down. Would that help?

    That its an intermittent fault.
    Unlikely if you are accurate in you claim that it never got wet.
    Much more likely its just an intermittent fault.

    Time will tell.

    Don’t believe it given that none of those of mine get anything like that
    hot.
    Still complete and utter drivel.

    You can't even manage a consistent line in mindless bullshit on that last.

    Apart from what other causes have been mentioned, that could also be the
    case. When you plugged in the laptop it caused the current in the power
    circuit to exceed 10amps, due to other appliances in use, causing the
    circuit breaker to trip

    That's 2400Watts, so not very likely..
