I check the power pack on my Dell computer and is only rated 90W. That is the max, running wattage would be less. My Dell is 3 year old. Modern day laptop would draw less, much less, power. So in short, your cigar light circuit would provide ample power.
Check the power pack of the laptop rating first before you mess with the battery wiring.

most cig outlet fuses are either 8 amp or 10 amp.
I've not seen any rated above 10...
that'd be a max of maybe 120w...
I agree on the cig adapters for a laptop though.
most are only going to draw like 80 watts... most cig adapters are I think, 120 or 100 watts... plenty for all but the most robust laptops...
Hmmm.
my cheapo toshiba laptop has an input demand of 1.5amps... at 120v, that's 180watts... wow.
output is only 3.95a at 19v... that's only 75 watts, of USE... so, the cig 100watt adapter should be fine for mine...
