    Hp dv6-7090el not charge battery (mainboard Goya/Balen 1.0-DDR3)

    Hi to all friends of the forum.
    This handset only has the problem of the battery that is not charged.
    When I plug in the power supply, the Orange Charge LED lights up for a moment and immediately becomes white.
    Battery connected but not charged appears on windows
    I updated the bios but did not change anything
    Here are the measurements made on BQ24738
    PIN 1 19.19V
    PIN 2 19.19V
    PIN 3 19,19V
    PIN 4 25V
    PIN 5 6V
    PIN 6 2,60V
    PIN 7 0,30V
    PIN 8 3,30V
    PIN 9 3,30V
    PIN 10 0V
    PIN 11 3,06V
    PIN 12 INCREASES FROM 2,70V AND STOPS TO 3V
    PIN 13 INCREASE FROM 2,70V AND STOPS TO 3V
    PIN 14 GND
    PIN 15 0V
    PIN 16 6V
    PIN 17 5.96 V
    PIN 18 INCREASES FROM 1.80V TO 3.20V
    PIN 19 INCREASE FROM 1.80V TO 3.20V
    PIN 20 18.70V

    I do not have another battery to do tests, checking the mosfets I'm not short

    PIN 15 & 18 Voltage is little suspect. Check All low and High side power mosfet.

      I would replace the battery first and make sure it is making good contact with the motherboard's connector.

        troubleshooting microsoft surface pro 4 no power no led charge light
        by ipatch
        hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

        Acer a515-43 low battery charge voltage
        by ruletero
        Hi

        Acer A515-43
        LA-H801P

        Fail: Does not charge battery, has low voltaje on connector.

        Laptop didn't want to turn on, only charge led blinked.

        I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...

        I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.

        Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know...

        Charge a L19D3PDA battery externally from the laptop
        by Klevjetack
        Is there a way to externally charge a L19D3PDA battery from the laptop. I have a broken charging port on my laptop and am trying to find a way to charge the battery for it. I have been doing some research and I have found that there is a module, TP4056, that can be used to charge Li-ion batteries. It says it is used to charge single cell Li-ion batteries. The L19D3PDA battery is a three cell battery. Is it possible to use the module to charge my battery and it would just be very slow? Or would that be a bad idea. Is there a different kind of module I can use to charge my Li-ion three cell battery?...

        How can I charge that battery pack?
        by razenxd
        Hello,
        it's not a laptop/desktop related question but I figured that someone here will have the right knowledge.
        At work we use a few Aldebaran(now Softbank/United Robotics group) Nao Robots which they use some custom 6S li-on battery packs.
        Nao robots tends to draw from the battery even if they are shut down, and the BMS tends to be a little aggresive, if the pack stays on a turned off robot for 3 months it's gonna lock and will refuse to charge.

        Now, I have noticed a few things.
        The "dead" battery, while connected to charger and NOT Charging will...
