Hi Ppls
Working on a Dell G15 5520, motherboard LA-L655P.
No power no LEDs; Ive tried all the basic battery disconnect, bios reset (even though it felt pointless with no charge indicator)
There is power getting to the board as there is heat generating toward the centre of the board, which I am presuming is part of the charge controller;
I haven't ruled out a faulty power switch so, anyone have schematics and board view for g15 5520 p105f to find safe jump points would be great, then I can work from there; or maybe you have had this issue?... -
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.

Hi,
I'm working on the TPM chip in a Dell Latitude 5420 Rugged. It contains a NPCT754J chip, but I cannot find pin-out for this chip. I have checked the service manual; https://dl.dell.com/topicspdf/latitu...nual_en-us.pdf - but it's not detailed enough to contain this information.
I've also checked Novoton's own documentation of the chip here; https://csrc.nist.gov/CSRC/media/pro.../140sp3187.pdf and here; https://commoncriteriaportal.org/fil...ible-cc-2018_6...
