Welcome to the forum!
Let's try this ancient trick:
Unplug the AC adapter, remove the battery, hard and media drives. Press the "power" button ten times in a row holding it down for ten seconds each time and thirty seconds the last time around.
Plug the adapter - but nothing else - back in and try to power on.

So I am no longer thinking it is the motherboard. I am thinking it is the coin battery now. It is a $5 fix if that is all it is. Considering the computer is over ten years old now, this would prove to be a likely candidate, no?

If you do some research on term " Blink Of Death" aka BOD, you'll find many stories similar to your own.
All A2x and T2x (apart from T23) units are prone to it, no known cause or solution. The problem's been around for a very long time.
Time for a replacement motherboard, or burial with honours.

i am in the same situation with my A21p 2629-H2G.
When i power-on the laptop i can see hdd and battery leds blink, a rapid flash of the lcd screen (i can hear a little "tic" comes from the inverter or the lamp) but the system won't post: i can't hear no hdd start (when plugged-in) and no cpu fan starting.
I made all these tests with only mainboard, subcard (the one that connects the lcd) and keyboard; without any peripherals like hdd, fdd, pcmcia, memory, modem card, eth+modem port.
I tried your suggests, as you wrote:
<<Unplug the AC adapter, remove the battery, hard and media drives. Press the "p<ower" button ten times in a row holding it down for ten seconds each time and thirty seconds the last time around.
Plug the adapter - but nothing else - back in and try to power on.>>
and i had no changes...
I'm sorry, but - yes - I also thought you're joking when I read "ten times in a row..." :-)
I tried all mix combinations with ac adapter, battery, backup battery: all inserted, one of them, two of them, head down and legs up, standup with left feet, cross fingers and so on...
I understand it could be another BOD case, but i would make the last trying: what about the J16 jumper located close to flash IC named U69 ?
I thought it could be something like cmos reset...
What do you think?
P.S. I beg pardon for my english :-)

Welcome to the forum, luxman!
My honest opinion: bury it with honours. Unless you can source a known good motherboard for next to nothing.
I love these oldies, but there's not much that there's left for you to try out short of a planar swap.
