Hello!
I have a problem with a Dell G5 SE 5505 laptop that I hope someone can give me a few pointers on.
[OK, it's not really a laptop, I'm running the motherboard on my desktop with only cooling, RAM and an M2 drive attached.]
I had some performance issues, so I decided to update my BIOS from 1.7.0 to the latest version, 1.20.0.
The computer restarted and the update dit not want to continue without a battery connected, even though I used dell's method of bypassing this requirement.

I have a Dell Latitude 5530 with a damaged RJ45 network connector. See the attached pictures.
Have already searched on Farnell / Aliexpress / Ebay and had contact with several suppliers on Aliexpress and Ebay, but they cannot deliver this connector.

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...
