Sony FS550/Targus Univ Air Adapter ... specs help ...

OK -- trying to find out which of the Targus APM12US tips (S11 or S12) will be compatible with a Sony VAIO FS550 ... or even if it will be.

The guy at the store said that it would be, but that it wasn't listed on the chart, as the Sony is still a pretty new model/series.

I'm inclined to agree ... so far, all of the other Sony models are listed & are either the S11 or the S12 tip (the FX170 I'm on is the S12) ... but I can't seem to find any comparisons between the power supplies between Sony models ...

I searched the model # for the Sony AC Adapter (VGP-AC19V11) ... the model on my FX170 is PCGA-AC19V1 ... both are 19.5V adapters ...

I'm leaning toward that the S12 would work on both ... but I'm just NOT SURE.

I'm still researching on my own ... but if anyone has any input, I'd welcome it!
