I'd be very very surprised if an original battery in a 9x7 still worked!

I'd also be mildly surprised (and disappointed) to find that anyone is
still using a 9x7 today ...
instead of something newer.  (Newer machines are incredibly inexpensive,
and provide a
lot better performance than most 9x8s, well ... at least for single
processor models :)

The low-end 9x8s (918, 928, at least) had a hole inside for a battery
backup ... but there is no
connector (thus, no way to make a battery useful).  I suspect that during
the R&D phase they hoped
to have internal battery backup, but the power draw of the newer 9x8 (vs.
the 9x7) was simply too great
(*or* the division selling the new HP UPS had something to say about
allowing customers to not need their product? :)
