Hello. I am really enjoying my newly acquired PowerBook 1400c.
However, each time I unplug the power, its time resets to early 20th century :-(
Searching the Forums this appears to be due a dead internal battery.
Is this assumption true and, if so, can the battery be replaced?
Thank you ... and stay safe 🙂

Sounds right to me. You can find instructions for how to get to the battery in the Service Source manual here: http://tim.id.au/laptops/apple/powerbook/powerbook_1400_series.pdf
I can vouch that these instructions are decent and reasonably clear - I just de-batteried my mother's old 1400 recently using it, and it's fine. You do need to take quite a bit of the laptop to bits to do so, but the only really fiddly bit is plugging the trackpad cable back in (which, at least for me, clumsy, required a lot of swearing).
I'm not sure what you'd replace it with, but it's basically two button cells of some description in a bit of heatshrink with some wires on it - I don't tend to replace CMOS batteries personally, just remove them to stop them leaking everywhere, but I'm sure someone else here knows what the cells are.

Thank you for the advice, and the pdf document.
