    my laptop was showing signs of a worn out inverter (screen was dull but image could be seen when screen was tilted). When the replacement invertor arrived I opened it up and disconnected the power cable ( red and green cable from the right hand side of the invertor) but the mulit pin cable found on the left hand side was putting up a fight to come out. while pulling it out with tweezers i pulled the cables out from the white plug :( being tired and slightly pissed off i tried to line the cables directly into the new inverter without using the plug to do so. a dunno why a thouyght this was a good idea at the time. Anyhow when i connected the battery back up there was a smell of burning suprise suprise and now nothings happening at all. no power lights, no fance , no nothing. have i knackered the mobo? or does anyone have any ideas were i should start with this?

    thanks in advance all

    Sorry to hear abou that

    If it was a works laptop I'd say its dead, but If it was my laptop (and I had to replace it) I would try the old inverter back on and check that you havn't burned out the new one.

    I'm not an expert on electronics, and just from experance, If there was a smell of burning this is usually caused by capacitors burning out. Look on the mobo for browning around any caps or if there are solid white stuff coming from the tops of any of them. also a capaicitor should be flat on top imagine a can of beans, but if its blown out the top will be domed (imagine the top of a bean can being pushed out from the inside)

    Well you have shorted something out and anything could have happened. The fact that it isn't powering up now means you have probably damaged something on the power supply regulators. You smelled burning which indicates one or more components have been cooked (could be anything, resistors, chips, caps, diodes etc). The chances of them being on the system board is high, as that's where most components are.

    You should give this unit to a specialist laptop repairer and expect a high bill.
