    Lenovo 330 no charge Battery

    Hello,
    Notebook does not charge battery. BQ24780S is installed.
    VCC=0V
    DCDET=2.8V
    ACOK=0V
    Charge controller has no voltage

    PD201 error?

    PR209= 10ohm

      PD201 error?
      Yes, it must be replaced.

      Before you do this -> remove all power -> meter in resistance mode.

      Check the resistance to ground of the Vcc pin that is showing the 0v.

      One meter probe on Vcc pin; other probe to ground.

      The resistance should be high. Concern is why this dual diode blew up on you.

      At this time, the dual diode is not passing through the DC adapter voltage to power the charger IC which is needed to boost the gate voltage for the DCin mosfets.

          Vostro 3400 (LA-K033P) won't charge battery, everything else ok
          by techfreak9356
          I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

          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...

          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...

          Lenovo P43s won't boot with internal battery connected – looking for help diagnosing battery issue
          by code share
          Hi everyone,

          I'm having an issue with my Lenovo ThinkPad P43s. The laptop does not power on when the internal battery is connected, but it works fine on AC power alone (battery disconnected). Once the battery is reconnected, the system becomes completely unresponsive — no lights, no fan spin, nothing.

          Here's what I've tried so far:
          • Power/EC reset (held power button for 60 seconds with battery and AC disconnected)
          • Booted successfully on AC power only with the battery disconnected
          • Visual inspection of the battery — no swelling, burn marks, or connector damage
          • Battery
          ...
