    Do not charge with battery HP PROBBOK 6460P

    DO NOT CHARGE WINTH BATTERY

    HP PROBOOK 6460P


    POR CN4 IN SCHEMATIC

    1-8

    1+2 = 0 VOLTE

    3 = 0.002 VOLTE

    3+4+5 = 3.3 VOLTE

    6+7 = 12.18 VOLTE

    Changed the pieces

    Q29= FDMC7692S

    Q34+Q20+17 = FDMC6675BZ

    U7= BQ 726

    IO = SMSC KBC1126

    The battery has not changed


    What is the solution Thank you

          The pin numbers on CN4 are backwards and not numbered correctly, but I get the idea.

          At 12.18V (4.06V per cell), that battery is either being charged, or it is mostly charged already. Have you tried a different battery?

          On the pin that was reading 12.18V... what is the voltage with the AC adapter connected? What is the voltage with the AC adapter disconnected?

                  sir i think current battery is have a damage cell so we need to change that poor cell,
                  or change that battery.

                      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...

                      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?...

                      Latitude 3301 not charge battery
                      by dclass-pro
                      Hi guys I have this dell that with the battery charged it turns on correctly, but if I connect the charger I get the charging symbol but it doesn't charge the battery.
                      I found the shorted charger PU4401 ISL9538h that had pins 14 and 15 shorted and I replaced it. but it still doesn't charge.
                      I noticed 2 things:
                      1) without the battery connected if I connect the power supply, on the SDA and SCL pins of the battery I have 0V I measured the resistance with ground and it is very high, if I connect the battery I have 3v on the 2 lines.
                      2) if I try to turn it on without the battery...
