    Dell E6410 no charging need help urgently. . .

    Hello all guyz,
    I'm facing a problem with Dell Latitude E6410 Which is "No Charging".
    When i turn on with battery the Laptop turning on very well but when i turn on via AC Adapter, just fan spin and then all gone. Turning on with battery when i connect the charger there is no indication that charger is connect or not. . . .

    I replace following Parts:

    PU10 = ISL88731 (Charging IC)
    PU902 = CD3301RHHR (Selector IC)

    There is anybody who can tell me the exact faulty part????
    I'm in a hell please help me out. . .

      Hello guyz,
      I noticed that When i connect the charger, there is no +3VALW or +5VALW but when i press the power switch the voltages suddenly appear, The fan spin and after a few seconds all gone. Fan is off and the voltages are gone. I've Changed MAXIM 17020E from a working Motherboard but same situation again. . . .
      Now, anyone have any idea. . . ??????

              Test these MOSFETS PQ30 PQ31 PQ32
              Components on Page 51
              check pin 22 ,2, 13 of 8731 IC
              check charger_src for 18volts
              check gate of PQ30 for volts also test PL14 for volts

                  i have test pin 2,22 and 13.

                  2and 22 pin have voltage but 13 pin has no voltage and src voltage also ok but pq30 gate no voltage .what should i do????

                      ASUS X54H laptop thinks it's always charging even with charger unplugged
                      by flat-earther
                      The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

                      Windows also shows ''Plugged in'' when charger is not connected.

                      This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
                      Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
                      If I let battery run out and say it has 3% Windows will...

                      Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                      by Bowline
                      My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                      Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                      My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                      The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                      I have tried multiple different Dell power adapters. My Dell...

                      Dell Latitude E7440 battery not charging only works on AC Adapter LA-9591P
                      by Grucha98
                      Hi, i have problem with dell E7440, battery is not charging. Idk all story. Original Dell Adapter broken up (its not give 19V) i guess first ac adapter broken up and it broken charging circuit in laptop. Laptop has clone battery (Green Cell)

                      Laptop works on clone adapter, and its not charging battery. Like on photo. I checked mosfets near battery plug. They are not shorted. But on PQ809 and PQ810 are low on diode mode (both 0.25V) I desoldered them and check on bench and they are good both 0.5V on diode mode. I checked only drain - source way. So its board circuit it should be higher,...

                      Dell G3 3579 (LA-F611P) not charging
                      by Robocop
                      Hey guys,

                      I've seen several questions about this exact issue, but I've never found the fix, so I would appreciate if we can start over the whole debugging process again from start to finish, for my specific issue.

                      In the BIOS setup, (see pic) the AC adapter is detected with the correct power rating, the battery is stated as charging (when plugged in, of course), and the battery health is stated as "Excellent" (as expected, since this is a brand new battery purchased a couple of weeks ago). However, the battery never charges (the percentage never increases)....
