I want to clarify someting about laptop power supplies.  I have a Toshiba that uses a 70W power supply.  The power supply died.  I can purchase a 90w that has the 6.30X3.0 MM adapter included.  I know that it will power the laptop.  

The question is the long term effect of using the 90w and the battery life or motherboard damage.

The 90W is fine.

The number of watts doesn't mean it supplies a constant supply of 90 watts.  It means it is capable of supplying UP TO 90 watts.  If all your machine asks it for is 70 watts, it'll just give it 70 watts.  Totally safe, nothing to worry about.

Nothing will happen to the mother board in the long run. You must ensure that  the DC out put voltage of the power adapter is same as the old adaptor. Also that it has the same type of connector which can connect to the laptop.

With all of the available Universal Laptop Power Supplys out there I was hoping to confirm my feeling [the laptop would draw what it needs in watts and that the voltage was a non-issue so long as it was correct]... I also felt that a 90W would last longer in the long run, as it would be more effecient.

Thanks for the confirmation.
