I have just purchased a Sony SZ3XWP/C, which comes with a 19.5V DC power supply. I also have 2 older VAIOs notebooks, a PCG-FX804 and a PCG-F709. Both of these came with 19.5V power supplies which were identical to each other. The one for the SZ3 looks slightly different and the label says it has 4.7A output instead of 3.3A on the old ones. Is it OK to use one of the old power supplies to run the SZ3? (I plan to leave one of the old power supplies in a separate location to save carrying the new power supply there and back).
