If you search Google groups you will see that the first appearance of
the term in a post ("lap-top") was in July 6, 1983 in a post by Dan
Chernikoff, referring to the TRS-80 model 100.

I think the precursor term was probably "lap computer." If you search
that on LEXIS/NEXIS the earliest hit is a July 4, 1983 InfoWorld article

BODY:
On the Pope's recent visit to Poland, American photojournalists covering
his tour had something extra in their camera bags.
Several of the photographers were carrying Radio Shack Model 100
portable computers to stay in touch with editors back home.
In the past year, the personal computer has gone through another
transformation in size. Now the microcomputer has left the office behind
and become mobile.
First it was the desktop microcomputer, then the suitcase-size portable
and now the true portable, known variously as the briefcase-, lap- or
notebook-size computer.
A good part of the notebook-size computer explosion is attributable to
Radio Shack's Model 100. Introduced several months ago, it is already a
big hit for the Fort Worth, Texas, electronics giant, and it has served
notice to other companies that a huge demand exists for reasonably
priced lightweight computers.
The Model 100 wasn't the first lapsize computer, however.
Hewlett-Packard introduced the HP-75 last year, and Epson has been
selling the HX-20 with a 4-line by 2-column display for almost two
years.

To search Lexis while avoiding the tags, limit the search to the body of
the article by searching "Date<1985 and body(Laptop or lap-top)". Doing
this will get you to a late 1983 ComputerWorld article that begins:

BODY:
Today's portables can be divided into several descriptive catagories:
the handheld units, the lap-top computers, the transportable units and
the integrated portables. These machines range in weight from several
ounces (the handheld units) to more than 30 pounds (the transportables).
The handheld units, just as their name implies, are typically not much
larger than a hand calculator and generally run on batteries. They are
limited in function and are normally little more than a combination of a
hand calculator and data entry terminal.
The lap-top computers fit smartly into most briefcases and are
considerably more powerful and capable than the handheld types. However,
these versions have limited display screens and limited memory. They are
also limited by the applications programs they can run.

Way back in July 1999, someone wrote thus:
>> Byte Magazine first used the term
"laptop" in reference to a
>> production
computer, after viewing the Epson HX-20 at a trade show in
November 1981. <<<
The original post is here:
http://classiccmp.org/pipermail/cctalk/1999-July/130419.html
.... but it's not true! Recently I looked through all the
Byte issues from that time period and found the reference in
question, which was in the Feb. 1982 issue. In the issue's
main editorial, on page 14, Chris Morgan referred to "...an
intriguing prototype of the Epson HX-20 personal computer...
The beginning of a new trend to what I call 'briefcase'
computers: battery-operated machines that combine portability
with powerful computer features. It's the sort of design
that will appeal to people on the move."
Byte's earliest use of "laptop" that I could find wasn't
until the Jan. 1984 issue, in an article called
"Portables--1984 and Beyond" by Dave Winer. I contacted Dave
and he said he heard the term from Ester Dyson, but Ester
said she doesn't recall saying it. She did say that
"luggable" was her term, referring to the suitcase-sized
computers. Byte did write about "lap" computers a couple of
times in 1983, but not "laptops" per se.
I'm bringing this up now because I have seen a few recent web
references which cite the 1999 post as fact.
Can anyone show me (not just say they remember) a pre-Jan.
1984 reference to the word "laptop" in the context of
portable computers?
I searched on Lexis-Nexus but the results were flawed.
Apparently someone tagged all the pre-1984 references to
"mobile" and "portable" computers with the word "laptop"
which may be logical for most searchers but doesn't help me at all.
