IRC 501[c][3] firm is seeking a decent "road warrior" laptop for field
operations.  Need PC to be donated.

Hello,

You may be able to find some assistance at the Charity Center.

The EDS (Electronic Data Systems) web site also indicates that it
donates equipment to charitable organizations. Their donation policy
and a link to their donation request form may be found here (scroll
all the way to the bottom of the page):

EDS states on its site that computer donations do NOT contain any
software and that all shipping and packaging costs are the
responsibility of the receiving organization.

You may also wish to contact the Cristina Foundation to inquire
whether they can recommend an organization to assist you.

There is also Gifts in Kind, which according to its web site, offers
"refurbished used computers through its Recycle Technology (RT)
program."

Gifts in Kind International

Another option may be:

Morgan Foundation

I also found this article from the University of Buffalo. It outlines
a host of resources:
http://cat.buffalo.edu/newsletters/comp_recycle.php

Search terms used included "donate laptops charitable organizations", 
"donate computer charity" and  "receive charity computer non profit."
If you enter those or similar terms in your favorite search engine,
you should come up with even more resources. Additionally if you enter
your geographic location or the type of clients served by your
organization in your search terms, you might weed out some of the
"chaff" in your results.

I sincerely hope that one of the links above will help you and your
organization obtain the computing equipment you need!

Best wishes,
