This device stopped charging and the battery I believe is now fully depleted. Will not boot on AC with our without battery. 3 blinks white blinks on DC LED then permanent orange (if battery is connected)
Seems live power is getting through the board.
Main question should this device boot on AC with no battery?

If the issue is not with the Ac Adapter, then it's likely to be a motherboard issue

OK. I guess no help is coming.
What happens when you press the power button? No sign of life at all?
So, you have already tried the hard reset? Here is how it is done:
You should also try to recover the BIOS
I would also try removing the battery and performing the power reset and try booting the computer. (page 33)
next, try removing everything from motherboard except RAM and try to boot.
