Hi Pat,

There are a number of companies that sell external laptop batteries.
Some have huge (relative to stock batteries) capacities.  And some come
in convenient "planar" form factors that neatly fit underneath a laptop
or even act as a dock-like unit that attaches to the bottom.

And I've heard of people getting 10--12+ hours of real work with
external batteries connected to, for instance, IBM X-series ThinkPads.
