There's no alternate power input besides the AC cord? If there is you can
look at items such as:

I have a compac 1700 which has a power cord that goes straight to it

I do know that some computers have a step-down converter that takes mains
voltage and brings it down to 13 volts so were that plugs into the
computer
it only need 13 volts which will normally run on a 12 volt system, that is
what I am after.

I believe they all can.

Look at the options available for whichever one you're considering,
usually
they have a DC power cord in the list.

Does any know which laptops run off 12 volt and therefore do not need
an
inverter I think the old Toshiba one did
