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?

You can purchase an Auto Power Adapter/Charger from Compaq
(#401043-B25) which is supposed to be an option for the
E500. Or, you can purchase a generic adapter. These adapters
will charge the internal battery as well as operate the
computer from your 12 supply.

Good luck!

I use a small 12VDC->120VAC inverter, and the normal laptop AC supply.
This may be slightly less efficient than a "proper" 12 volt supply for
the notebook, but it is cheap and simple, and I generally have the
engine running while using the computer, so the loss in efficiency is
not significant.

Look for a auto/airline DC adapter. It takes the nominal 12V battery
voltage and provides a stabilized 18V output. Adapters were made by
COMPAQ and there are also after market adapters on the market.

Check eBay, there are about 20 Armada DC adapters for sale there right
now http://tinyurl.com/72ftb

Hi Geert,

In Belgium you should be able to get a Targus or Kensington generic auto
adapter for your laptop at most bigger computer shops.

I know that Office Centre has them in the Netherlands, and they have 3
outlets in Belgium: http://www.officecentre.be/

Also check the nl.sport.varen newsgroup, someone asked the same thing
there this week (search for "voeding laptop").

You might consider the risk of voltage drops when cranking the engine if
you have removed your laptop batteries, which otherwise can protect you
against that. This device handles such problems nicely, at a price of
course....
