- Power cord from 17" on a 14" Dell

Over the weekend we exchanged power cords by accident.
He plugged his computer in and received a message saying his computer
could perform better with a different power supply. Meaning he plugged
my adapter into his computer. I think mine is rated at 75W.
His, the one I now have, says 90W on the back. Now his computer won't
get damage by ryunning a lower wattage (except poor perf.), but can I
use his 90W in my laptop without damaging it?
Re: Power cord from 17" on a 14" Dell
that the supply is CAPABLE of supplying, but the laptop determines what
is actually delivered. However, the voltage, polarity and connectors
must match. And Dell is using "intelligent" power supplies that "talk"
to the computer, so you can't just use any old power supply, even if the
voltage, polarity, connector and wattage are otherwise ok.
