  1. It would be better , first of all , to declare :" Only good with very old battery model with simple BMS included."
    Now recent BMS have a built -in chip which refuses current output after repair if they are disconnected (necessary for changing the 18650 elements) So, after changing you have good voltage at the main ports between battery and BMS…but nothing at the BMS output.

    If the battery is not completely dead (not 0V) ,a possible solution (I'm not sure) would be first to connect the BMS to another 12v source , so it keeps voltage when we cut the wires…But now BMS are really "sophisticated" : if we install new fully charged batteries, they detect other batteries and not the genuine , and lock the output….Possible that in the PC the installed Bios makes the same…Nothing to do with computer safety…but with seller safety!

    In the future with ALL lithium batteries , the problem for us will not be the elements but the deliberate complexity of the BMS and the communication with the charger or the tool itself…and you understand why….They will do the same as for printer's cartridges …and explain it's first of all for safety (??). I have the same problem with E-Bike batteries. And I don't know with the new screwdrivers?…

  2. I need help please , when I connected the positive end of the battery to the p+ pin it sparks but
    connected the the positive end of the battery to p – pin but nothing
    No success
    Battry is Hp pro6
    Hp battery for 4440s
    Please urgently need help

  3. Thank you very much! worked for me too! the original battery is not available anymore and the replacement battery did not charge and Windows said no battery detected. i took the cells out the replacement battery and put them in the old battery and jumpstarted the old bms using your jumpstart trick. i would have had to buy a new laptop if the battery could never work again.

  4. My results:
    After replace the battery cells, the voltage in the connector is equal 0. Then i tried to

    touch a wire in the positve (battery cell) to positve (connector) and nothing, tried too with negative and still 0v. Not working to connecting negative to switch, but if i do a jumper between postive from cell to positve from connector, i have 14,60v and i can charge on laptop.
    If i remove the wire, nothing work.

  5. Hello sir, please help me
    I did replace the cells and the bms connector is not showing any voltage, I also did the method you shown ,
    The fan working when giving direct voltage but the battery /bms is not resetting
    Plz help me

  6. I have an HP Envy laptop, it has 3 batteries and these have a good voltage of 3.7 volts, but there is no voltage in the terminal block slot, I have tried to do what you do in the video but I am not sure which are the positive slots and the negative.

  7. Hi, I have tried above method with no luck.

    I have replace the battery cell and then run the HP Battery Check apps, the result :

    Cycle count = 343/300

    Design Capacity = 2792 mAh

    Full Charge Capacity = 1 mAh (0%)

    Remaining Capacity = 0 mAh

    Current = 0 mAh

    Terminal Voltage = 15436 mV

    Design Voltage = 14800 mV

    Cell Voltage 1 = 3814 mV

    Cell Voltage 2 = 3903 mV

    Cell Voltage 3 = 3767 mV

    Cell Voltage 4 = 3953 mV

    is there any way to reset the battery controller lock?
