if you say your laptop works on 19v DC
then to connect it to a 12v car supply you need
a 12V DC to 19V DC voltage converter
you can see them for sale here http://www.powerstream.com/19v-index.htm

What a stupid thing to say.... about a car driver connecting a laptop whilst driving...... that would constitute.... "driving without due care".... in the same way as using a mobile phone....
(as a matter of interest.... did I mention connecting my (any) laptop whilst driving ?)

it does not involve a 240volt or any other converter
its just steps up 12v to 19v by electronic design means
but no matter my postings are correct

As a designer I use tried to avoid DC to DC converters as these can emit high frequencies and is a consideration for EMC.
