Hi,
I just bought a replacement AC power adapter and the amps are slightly higher than the original (3.4 versus 3.16). As long as the voltage is the same (19v), it should be fine right? If I remember correctly, the max output is Volts x amps and my computer will draw what it needs. My biggest concern is frying the wire.
Yes.

Insure the polarity is correct and that the replacement is a REGULATED
19 volt supply.
The extra current capability of the new power supply will only be supplied if needed. The assumption must be that your original power supply was enough for the load, so for the same voltage your new supply will putting out the same current as before. So you are correct.

Should be fine. There are exceptions like battery chargers - but even in that case you should be good to go.
You won't fry wire with that power differential unless the original wire was giving off heat or light . . .
"AC power adapter" and "DC power adapter" aren't the same. In some cases you can use a DC in place of an AC and visa versa - but if that's the case tell us.

Have you seen any 3 A supplies that weren't regulated?

Point taken but I was thinking some schmo would call a bridge and a cap regulated.
