I assume that the laptop in question requires AC power and does >not run off a battery... i was wondering about all this discussion of inverters, too, unless the original question was about an old grid or somesuch. my machine (no hard disk) is supposed to draw 1.1A at nine volts. so it seems to me i could use a solid-state series-pass regulator along with the car electrical system. it would need enough heat sink to dissipate, say, four watts. if you're not into building such gadgets, then i would look to see if radio shack had something capable of supplying the current. brian
