Is the battery old? Are you able to check the # of charge cycles on the battery? The power adapter is the original and suitable for use with this laptop?
If there is a doubt on the above details of the battery - test with a known good battery first.
Do you have a multimeter to check on the voltages? If yes, meter in dc volts scale (20v or higher is ok). Carefully measure the voltages to ground on each pin of the battery connector while the power adapter is attached to the logic board.

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... -
1. Some theory
1.1. Introduction
Almost every laptop has a charging circuit of some sort, that does a few things:- Manages switching between AC adapter and battery power
- Manages battery charging and generates power rail to charge battery
There are 2 different designs to handle switching between AC adapter and battery power and feeding the system:- Hybrid power boost (HPB) and traditional circuits without power boost (see Warning in HPB section)
- Narrow VDC (NVDC)
Texas instrument has a nice overview of these technologies with some more details at https:... -
since i couldn't find schematic or boardview for this model (LA-K062P), i use closest board model found here https://www.badcaps.net/forum/troubl...-and-boardview
the schematic share same marking for each component, using same PD-Controller, same BQ25710, the only different is the battery cell used. LA-K061P uses 3S battery while LA-K062P use 4S battery per schematic.

Hey All!
Long time forum member here with a problematic laptop issue!
I got a RZ09-0196 with a bloated battery (still worked and charged fine) I pulled the old cell pack out and installed a new cell pack in its place.
The laptop would not power on with the new battery installed without the power supply being plugged in.
When booting into Win10 (all up to date BTW) I saw the battery icon with 49% plugged in not charging.
TL;Dr version, old battery worked, charged but was bloated, installed a new non OEM replacement, laptop/windows... -
Hello everyone
I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).
I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,...
