Hello, I currently have a Dell XPS 8940 in our office for repair.
Service Tag: HG1Y673
The most recent BIOS is pictured below -- being available as an .exe on Dell website.
Needed a new motherboard due to power surge. The motherboard replacement was installed and upon power up it was booting to a display message - Manufacturing Mode Active -

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
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...
