I've just plugged an 18.5V 6.4A HP power supply into an HP laptop; I normally use an 18.5V 3.5A power supply. Since the connector fit, I figured I'd give it a go... so far no funny smells or fires.

Is this setup doomed to failure or will all end well?

Unfortunately I've forgotten everything I learned in high school...

This is fine. The amperage rating for a power supply indicates how much current it is able to provide. Your laptop won't draw that much current, so it won't damage anything.

Sounds ok to me. I've run HP's 90 watt adapter for several years on a laptop that came with the 65 watt adapter. I wouldn't advise going the OTHER way, but as long as the power supply can supply more current than the laptop asks for it's no problem.
