Art, Thanks for the info. I guess i didn't really need to spend the extra $20 to get the 90W AC adapter for my new Latitude D410.
I have a second question that hopefully you can help me with. I was reading this link regarding using portables outside the country
it states that the AC adapters can handle 90 - 276 volts. This will work well for me in Australia. But, the thing is that the article also states that the power cable that comes with the AC adapters is rated to handle only 115V which is great for the USA, but in Australia the voltage is 230V. I looked on the Dell website and the highest voltage rated power cable i can find is 220V. Does anyone know if Dell makes a power cable for the D410 AC adapters that is rated to handle 230v or 240V?
