    Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
    by Bowline
    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...

    DIY 3D-Printer WSON8 Pogo Pin Adapter
    by langbaobao
    Hi.

    I'm posting this here in part as a memo to self as well as to describe the procedure I used in case anyone else found it useful. I found a lot of the necessary information to make this work on this forum and I figured I would give something back. If this is not the appropriate place to post this, I don't mind it being deleted but I hope it can help other people.

    I got an admin password locked HP Elitebook 840 G5 recently that I wanted to unlock. I'm a relative newcomer to reprogramming and unlocking firmware. The only previous experience I had was unlocking a BIOS...

    Vostro 3400 (LA-K033P) won't charge battery, everything else ok
    by techfreak9356
    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.

    ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
    by Document Archive
    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...

    by ferah831208
    Hello guys, i need help with this problem, I have a NM-D041 mobo, it came with low impedance in 3v linear regulator rail, the cause was a damaged EC controller ITE8227e-192. I ordered a new one and replaced it. This laptop have a different chip for keyboard management and it8227e pins for programming ITE chips are not accesible through keyboard interface, I flashed it using i2c interface pins with vertyanov programmer because laptop was dead and SPI flash didn't have power (only 3v EC) so it couldn't access firmware stored in SPI memory. I read SPI and extracted it8227 firmware from original BIOS...
