How many watts does a monitor and laptop consume?

I have a 22" lcd monitor and a Laptop I need to bring to an outdoor expo to present a powerpint, I'm not going to have acess to an electrical outlet. I have strapped 2 massive twelve volt deep cycle marine batteries together with a 200w power inverter. Anyone know if that will be enough wattage? I can't find any specs on the equipment.

my 24in monitor specs at 55 watts and if you have a non-gaming laptop it will use definitely under 100 watts. so I think you will be fine. why don't you test it first before you go, just to make sure.
