    Bizarre laptop I/O error when battery charging.

    Here's one that has me stumped, perhaps some of you have come across this odd problem.

    I have an old HP Pavilion P3-600 laptop Win2k), and an old Sotec manufactured Coppermine Celeron laptop (WinXP), each exhibiting the strange behavior of both the touchpad and keyboard stops accepting input momentarily when a 'new' battery is installed and 'charging'.

    It cycles every few seconds. 2 seconds dead, 4 seconds fine.
    Remove the 'new' battery and the laptop returns to normal input.
    New is quoted because I can't verify their condition as neither appears to be charging. The seller claims they are new.

    The HP's battery light goes from amber, to red. The old dead battery stayed amber, and didn't affect the inputs.
    The Sotec's battery lights don't seem to light up at all. Old or new battery, the inputs go dead.

    It seems like a M$ OS issue. ACPI problem? Inputs don't get buffered, just lost. Would a bad battery cause this? Or missing service or driver preventing charging as well as the input fault?

    Stumped!

      If you shut the laptops off, will they charge?
      Ludicrous gibs!

        No, they won't.
        I am assuming the batteries are bad. But I've not come across the strange behavior before. A non-charging battery shouldn't cause this. ???

        The Sotec/Averatec-made Celeron laptop has a battery utility within its BIOS to monitor the status of the battery. It first tops off the battery. And it shows its not charging. So, it's not XP preventing the charging at least....but something is causing the OS's to lose I/O.

          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...

          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.

          Laptop battery charging circuit
          by piernov
          1. Some theory
          1.1. Introduction
          Almost every laptop has a charging circuit of some sort, that does a few things:
          • Manages switching between AC adapter and battery power
          • Manages battery charging and generates power rail to charge battery


          There are 2 different designs to handle switching between AC adapter and battery power and feeding the system:
          • Hybrid power boost (HPB) and traditional circuits without power boost (see Warning in HPB section)
          • Narrow VDC (NVDC)

          Texas instrument has a nice overview of these technologies with some more details at https:...

          How to Test if Laptop is Charging The Battery
          by Zentech
          guys, I have a laptop hp chromebook 14 and the operating system was not recognizing the battery. I opened and tested the battery connector to the motherboard for output. I found like three different voltages must of them 3.3V. Then I looked online for voltage of motherboard to battery in HP laptops and found the pinout of the connector. Needless to say I was surprise to see that the laptop doesn't charge the battery with 12v. I tested with the meter and it was like 3.3V in three different pins and two of them were ground. Then I search for articles on how to test battery and found this

          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...
