WE have the schematics/CLIP for the 70004A but there is no schematic
for the A3 display section proper . This usually implies that the
display was originally a3rd party drop in and not a Agilent design
The Service Guide refers to the battery being on the A5 board and
elsewhere talks about a red LED error light relating to a battery
failure. But I did not see a part number for the battery, there is a
crude drawing showing the location on page 4-10 in the service
guide.

Thanks for the info on battery location, I went through
the manual, and did not find it, or any parts shown for
it. it is not shown in the error messages either, which is
disturbing.
what possible purpose does this battery serve, and why is
there also one in the display? does anybody have a part
number for it, so I can get a replacement on order before
I rip the unit apart?
I am aware of the LCD replacement (I have one waiting to
install), but was just wondering if there's an internal
intensity limit or contrast I can tweak to get a bit more
life out of this display before I go that route. I don't
see any schematics in these manuals so it's not as helpful
as it might be in that regard.
does anybody have a true hardware level 70004A manual with
schematics?
all the best,
