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... -
I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
configurable for operating as either a Hybrid Power Boost (HPB)
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
4-cell batteries. Both configurations allow the battery to work with
the adapter together to supply the system load when it exceeds
the adapter capability, referred to as system Turbo mode. HPB
charger configuration reverse-boosts battery energy to the system
bus to help the adapter provide the system power in Turbo mode.
NVDC charger configuration...11-05-2024, 03:28 PM -
Hi,
A friend of mine gave me an iPod nano G3 to see if I can fix it for him.
The device had a faulty battery and he tried to replace it but failed. In the process he managed to pull off the pads that corresponds to the white battery wire (marked with a red circle in the images)....from both sides of the PCB. Fortunetely he didn't damage anything else.
This is usually an easy fix HOWEVER, on the PCB, I see no traces coming from the VIA and after searching the internet, I've found no schematics nor boardview for this device. With the pads gone from both sides I seem... -
ISL6257HRZ ISL6257HRZ-T Laptop Battery Charger Datasheet
Highly Integrated Narrow VDC Battery Charger for Notebook Computers
The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
Narrow VDC applications where the system power source is
either the battery pack or the regulated output of the charger.
This makes the max voltage to the system equal to the max
battery voltage instead of the max adapter voltage. Operating
at lower system voltage can improve...11-05-2024, 04:43 PM
