Nope, watts is volts times amps. Resistance is not the same as watts. So, 16 volts X 2.6 amps is 41.6 watts, and 12 volts X 3.5 amps is 42 watts. That's the power consumption, not the total.

So we pull out Ohms Law which states R = V/I (V= Volts, I= > Current, R= Resistance). Resistance is the same as Watts in this case. > > So... > 12 / 3.5 = 3.429 Watts > 16 / 2.6 = 6.154 Watts > > > > On the bottom of the Laptop ... the power requirment is listed as 16 > > Volts / 2.6 amps > > > > On the bottom of the 12 Volt to 16 Volt Laptop Power Converter the power > > requirment is listed as 12 volts / 3.5 amps > > > > Am I correct in assuming that the Total Power Consumption for the Laptop > > and Converter is 3.5 amps? > > > > I don't believe it could possible be the total of the two which would be > > 6.1? > > > > Larry Chase
