Of course I went in detail, through the links for BIOS Guides.

2. ----4(G) and 5,6,7,8 (D) 0.00 Ohm
3. ----1,2,3 (S) and 4 (G) 0.00 Ohm

Can you please check the attached pdf with voltage measurements?
Do you suspect any faulty fet so as to check the resistance between S-D, S-G and G-D?

I will measure and revert
BUT
I have checked with two different Power adapters

with an HP USB adapter (since this USB port can be used to charge the Laptop)
Same Behavior with all 3 adapters no orange LED lights on
Furthermore when battery was having some power (before it run flat) and I have run the battery /power test from the BIOS, it was saying that no power adapter is connected.

Re: Zbook 15u G6 (PR/ID 4YW47AV) not charging
That is really very interesting. It might explain to me why a DELL battery which I have rebuild a couple if years back was not successful and why I could not charge it.
I have to dig in the old stuff and test it.
So interesting. Thank you very much...Leave a comment:

Re: Zbook 15u G6 (PR/ID 4YW47AV) not charging
Thanks alot. I will be studying and proceed accordingly. Of course this is not an immediate solution, but it will improve knowledge in the laptops battery management system.
I might proceed with the aliexperss items, but it takes a hell of a lot of time to reach Greece
I will concentrate (subject to your and forums assistance) in repairing the board (subject also to spares availability).
May I ask you to look into the measurement I have done in the 2nd DC in mosfet (in case you identify anything...Leave a comment:
