    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...

    Strange battery present behaviour in Lenovo Legion 5-15ARH05 mb model nm-d041
    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...

    HP ELITE X2 1013 G3 weird battery issue
    by huzo
    Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...

    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...
