Hi!
No! You were *definitely* correct. I'm here to say that substituting laptop
power supplies between different models and makers (as long as the
connectors are completely compatible!) is generally OK as long as you have
checked the voltage (both listed and what is actually being put out when
unloaded), current rating and polarity *first*. The voltage should be exact
and the polarity had better match as well. Current supply can be higher or
equal to what the computer expects.
There is some leeway in most designs for current draw and possibly voltage,
but you can't always count on this and won't find it documented anywhere
short of personal experience.
If you don't check these factors before plugging things in, you're looking
at the possibility of causing anything from instant destruction on up to
slow cumulative damage to the computer.

I was horrified that he hadn't checked the voltage the amperage or the
polarity. He knows more than me about computers, but was he right
to not check these things
