My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -

I have a Dell gaming laptop here with a blink code of 3 red, 5 blue (power rail failure). 3V and 5V are present, but 1.8V is missing. I looked at PU1801 according to the schematic, and it's not receiving an enable signal. Any ideas where to check next? I think that signal comes from the PCH.
No obvious shorts under thermal (or probed), damaged components, liquid, etc.
