I suspect that the cheaper square wave or modified sine wave models have harmonics whichI bought the 150W model from Maplins for my Mac powerbook but it won't work with it. It keeps signalling an intermittent fault, almost alternating. I bought a 300W model from PC World and that is at least charging it. I hope it doesn't fry it!
can somehow upset the electronics of the chargers, but I now use a pure sine wave inverter

Best wishes. Patrick.
