    Notebook not working with battery

    Hi everybody .

    Please can you help me.
    I have a Toshiba C55-A PT10FG notebook board.
    When I use only the adapter (without battery) everything works normally.
    If I use only a fully charged battery, the notebook can not be turned on while the charging LED flashes.
    If I plug the adapter when the battery is connected, there is no change.
    When I turn on the laptop only with the adapter and plug the battery the notebook works in and system i see battery information serial number, capacity etc.
    The system shows that the battery is fully charged, as shown by the capacity.
    The battery is new but not original.
    When I measured the battery with a multimeter, it showed a 11.4V peak.
    I replaced the BIOS, EC BIOS, ITE8572, BQ24725.
    I do not know what to do next.

    Thanks in advance for every type.

      Check mosfet on discharge circuit. On 1 end you should have battery vol and on the other end you will have ac voltage. check this mosfet-if it is open then also you may face this problem(Since you have already replaced charging IC)

          This mosfet I measured.
          When the inserted battery is closed, it means one side of the battery is 11.4V and the other side is powered by a 19V adapter.
          If you disconnect the adapter, the sides of the power supply are 11.4V.
          It's okay for me or I'm wrong.
          When I disconnect the TS1 # C signal from the battery, the notebook turns on but after about 5-10 seconds it turns off.
          This situation occurs only when I have a connected battery.

              after long testing I found that the new non-original battery was defective. I used another one and everything works normally.

                  ACER Aspire V5-473P-5886 does not turn on with fully charged battery
                  by mferna14
                  Hi, today I am working on an ACER Aspire V5-473P-5886. The laptop turns on fine with AC power & in Windows 10 it shows the battery ICON & the charging percentage & the AC power plugged in, but as soon as I remove the DC-in jack power cord, it just turns off too. I charged the battery external 100% by shorting the Battery ( AP13B3K ) enable (Yellow Wire) to GND. Now battery Voltages shows 15.2 volts. Even check with a Known GOOD battery of the same kind & model, problem is still the same. I checked all the MOSEFT on the motherboard, they all seem to be ok. I think this yellow wire...

                  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

                  iPad Air A1475 Boot loops after replacing battery
                  by trepachka
                  This iPad was working fine except the battery was not holding charge for more than 40 minutes. I replaced it with a new battery. I haven't glued the battery yet, just inserted it into the slot and held it with battery screw.

                  The iPad was powered on with the new battery and I am getting white screen with Apple logo for about 10 seconds, then the screen turns dark. It then cycles like this forever.

                  I know the battery is working because the iPad continues to boot loop without the charger until it depletes to 0% and the message displays I need to plug in the charger.
