    Can we "force" a "wake" on a laptop battery ?

    Hello!

    Question about friends laptop ,works great Lenovo E560 ,all good all fine. The battery is with 98,9% health percent, with BatteryInfoView, but it doesn't charge.
    We tried another battery (from my laptop and it charges just fine).
    So the problem is with the particular Battery.

    My question , and my thinking is (some cell might have died and the controller just suddenly takes it off) , so i was thinking if i can "ground" her or "force" some juice inside ,just to wake up the controller ?

    (It's silly i know,but it's shame for a good battery to be dead,and it's expensive).

    So that is my question ? (Maybe the Multimeter to be put into left / right corners for + / - ,wake up with the - ground to another pin to count the voltage,and then put the bench supply into +/- and put the battery into shake mode.

      Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
      by serious_electron
      Hello Everyone!

      I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.

      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...

      But when laptop is powered on through battery only the laptop does not power on and there is 0 voltage on battery connector.
      I have not not tried another battery as it is not available locally could this be a battery problem.have checked discharging mosfet and there is no shorting to ground on any pin of battery connector.
      The schematic is not available...

      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...

      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...
