But not necessarily 12 volts DC.

I have three ThinkPads that run on other than 12 volts DC and have the 
factory DC adapter for each of them, which replaces the AC power pack.

Never had any issues with any of them.

The inverter designed handle the step-ups if required, or voltage 
regulation circuitry if not, and is built into the factory laptop DC 
power adapter.

Even on a laptop designed to run on 12 volts DC, you may want to take a 
look at the manufacturer's recommendations for 12 volt DC powering. Not 
all laptops have filtering adequate to protect them in an unfiltered 
automotive application, and DC voltages on an automotive system can vary 
wildly depending on the battery's charge state and any active charging 
going on. See what the manufacturer of your laptop recommends.
