    Portégé R30 amny strange issues

    hello
    i need some advice for a porte r30
    initially the laptop drop with cable plugin, the laptop shutdown and the cable broke
    the owner try to replug it broken and pc never came back

    so i disassembled it, some caps where disconnected (strange as they are solder on this one : not directly on board but on some plate which they are solder on board)

    no damage at connector

    the laptop power on with cable. works but fan spinning fast with only 48° on CPU/gpu
    after power off , it doesn't start again. need disconnect the rtc battery , and then it can power on once again.


    it doesn't start on battery, but if i start it with cable plug, i can unplug the charger and the laptop works fine with fan spinning fast

    when i start it with rtc battery it says : rtc low, but when i test it it gives me 2.6V (it is a 2/15RH battery normally at 2.4V)

    don't understand what can cause all this issues :
    -start only plug but charge correctly the battery
    -start once a time, need reset bios to restart
    -rtc battery detected low but test ok

    have you an idea ?
    thanks

    Re: Portégé R30 amny strange issues

    hello

    more informations
    i send a picture to explain;
    when i plug the charger i have 18V on green points, 18V on red point and 3.3v on yellow
    when i plug the battery ; i have 11V on green points, 0,4V on red one, and 0V on yellow

    and i have not the 3.3V on power button with only battery plug.

    so i think that i have an issue activating 3.3V and maintain main rail on battery. the battery delivers 10,8 normally and it is fully charged. after start the laptop with charger i can unplug it and the laptop continue working on battery.

        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...

        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...

        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...

        Milwaukee M18 HD12.0 (12 amp hour battery pack) unbalanced failure charger refusing
        by sam_sam_sam
        I have two Milwaukee 12 amp hours battery packs that have an issue with battery cells very unbalanced these are probably over 4 years old and been heavily used in the past but now get occasionally used heavily and when I went to use the grinder tool the battery lost battery battery power very quickly so I decided to open it up and found some battery cells voltage from 3.6 to 4.1 no wonder the battery charger was not fully charging them 3 out of 4 LEDs were on meaning that it was only 75% charged

        So I have put them on the battery testing machine to drain each battery cell down to...

        Texas Instruments bq24745 bq24745RHDR bq24745RHDT Battery Charger IC for Laptop Computers Datasheet
        by Document Archive
        The bq24745 bq24745RHDR bq24745RHDT is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface. The bq24745 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5-mm x 5 mm QFN package.

        The bq24745 features dynamic power management...
