Yes those line of business laptops are nice - I wish mine was like that as they are 11.1V spec so can readily accept 12VDC without any conversion.
The only reason I've kept mine is it has a DB9 rs232 port on the back - rare for laptops these days. But everyone is heading for USB so I'd take the 12VDC option over a DB9 port spec anyday. I did try mine with 16V and it booted but locked up - just unreliable. Probably pays to check if one's laptop is already spec'ed for 12VDC otherwise one would be wasting money on a DC-DC converter.
