    E6430 charging problem

    Hi dear friends
    I have a dell e6430 that works perfect with ac adapter (ac adapter is detected correctly in bios) and also works on battery
    But when battery is installed the charger cuts out when you plug it in
    I disassembled it and found out the charging circuit sends adapter voltage directly to the battery
    By visual inspecting i discovered the cd3301b ic is burnt
    I removed that and problem is still there
    I found a couple of videos for bypassing the ic but not exactly on my motherboard and the ic isnt available on the market to replace it
    I guess its for controlling the charging circuit between two batteries of the machine (its just my guess)
    So is there any way to bypass that ic if i only want to work with just the primary battery?
    I really appreciate any help
    Thank you very much

      HP Probook 470 G4 - Power and Charging Problem
      by Scoff
      Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
      Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

      Lenovo E15 / NM-C421 Charging Problem
      by roman728
      Hello guys,

      I have a problem with charging circuit in this laptop. Unit came with no power at all (USB-C meter was cycling turning off and on). I discovered that when I unplug battery laptop works on charger only. So after few measurements I found shorted 1st dual mosfet AONY36324. Unfortunately i was not able to order exact this one, so i ordered AONY36352 which i believe is the similar one. Now the problem is, when i connect battery and charger USB-C meter is not cycling anymore, it starts charging (reading 20V@2,7A) but after few seconds it is going down to 20V@0,20A and laptop...

      Edifier x3 Earbuds Blue Light Problem (Charging Problem)
      by kity92
      I ordered a Bluetooth earbud one and half year ago, and right earbud broke. The light that should have been red when you put it in the charging case started to turn blue continuously(which means earbud is not charging) and after 1 week the earbud completely died. I disassembled right earbud because the warranty finished. I diagnosed the battery was dead, so I charged it with TP4056 and revived the battery.

      Right earbud is working now but I still didn't solve charging problem. I checked the charging box with a multimeter. There is 5V. I checked the headphone pins and they are working....

      Toshiba Qosmio X755 Charging problem
      by delphi_firebird
      Hello Guys,

      I received Toshiba Qosmio X755 that has a charging problem and I'm stuck trying to figure out the problem.

      - When battery is unplugged i works without any problem.
      - When I plug in the battery after plugging in the charger, it works correctly and the battery is charging.
      - When I plug in the charger after inserting the battery, it stops working. ( voltage dropped and consumed 8A, reaching the maximum capacity of my bench power supply for 5 seconds, and stop working after )

      Can you help me diagnose the problem? I have attached...
