I want to connect a Compaq ARMADA E500 to a 12V batteries. The adapter
from the notebook gives my a 18,5V/2,7Amp.
Do I need a special converter? (where can I buy one)
Does anyone knows a wiring Diagram?

===========================================

Your cheapest solution is to get a low power/low cost inverter. I
don't know where you are located, but here in the US, West Marine,
Walmart and Costco all have inverters in the 150 to 200 watt range for
less than $35 USD. They will run your laptop just fine as well as
other low power electrical gear.
