I had the same problem with my Portable 386 because
the PSU died, when I
disconnected the hard drive it started up ok. All I've got left of it is a
pile of spare parts, e.g. mem board, Weitek etc. I don't know how different
it is from the Portable III. The CMOS battery lasted around 12 years, so I'm
not too bothered about replacing it with another (although expensive)
lithium.
I've been fortunate with my P/386... Found it at a Goodwill, as a
rebranded "Network General Sniffer" box ($20!) with the backpack
containing old thinnet and token ring cards... After putting the
cards up safe, adding a modern 10bT card, archiving the operating
software (DOS and Network General OEM software), adding a 387, and
installing a Linux CLI (6MB of RAM), it's been a pretty sweet
terminal/compiler/toy box...
*knocks on wood* My CMOS battery is still good, as is the 40MB Connor
HDD. Long live the good years of Compaq!

PS: And praise the Gods this one still worked after I reassembled it,
not like my last Portable III.
