    Is your (USB) camera working ?

    Which connector are you testing ? Check that the local EMI filter is present and not damaged.

      Hey, no worries anymore. I've figured it out while you're offline. Haha
      The bios has a hidden panel(because it's HP and it's an old laptop ��������)that sets security level to Default(probably by reset) it has 4 options(hide, default, view, change). I don't know what these values mean even on the user manual online but I changed it to View. The ports started to work and draw power including the data lines are active.
      Everything is stable now, I repasted the dry thermal Pad on the GPU and CPU including the
      South and North bridge. I got the And 7570 GPU version as well instead of Inter HD graphics ����. All in all, took me almost a 1 day and some sort of a sleepless night �� to figure things out. Thanks to you and your help. I've removed the ESD diode from the backside of the Cn6050(Second battery connector) and have it used on the first that we removed. Problemo Solved.

      Here's a small set up I've bought along from working in BPO.
      It's not much but has done the job pretty well.

        Thanks for taking the time to edit and point out stuff over the schematic.

          Btw started to read Charger Schematics starting with mine and now Trying to understand how this thing works. It should lead me to new discovery as I dont work normally with these kind of complex circuits with many logic inlcuded in the power supply circuit. I went into reading 3+ charge controllers schematics and datacheets and understand them somehow ))))))))))))))

            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...

            Lenovo Yoga C930-13IKB EYG70 NM-B741 Battery not detected.
            by mrkmpn
            Hello, I have a customer that brought this laptop in after replacing his battery. He said his original battery charge was not lasting long, and after replacing the battery with one purchased from iFixit, the charging worked for about 30 minutes and then stopped, and the battery is no longer detected by windows.

            This laptop powers on when the AC adapter is connected, and my USB-C multimeter shows current being used with both ports, but the charging light does not come on, and in Windows the battery icon shows an X as if there is no battery present. If I disconnect the AC adapter,...

            ASUS X571 no power : battery issue?
            by mkdj
            Hello everyone,

            Mark and model: ASUS X571
            Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.

            Tests already made:
            - Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
            - I have removed...

            A2338 820-02020-A | Battery Not Detected/Random Reboots
            by grimacelord
            Hello,

            I have a A2338 MacBook Pro here that came to me because the battery wasn't being detected. The owner tried to replace the battery themselves thinking that the battery was the problem but the behavior continues even with their new aftermarket battery. They also accidentally ripped off the black plastic clasp to the battery flex cable connector @ J5151, but I pulled that off of a donor board and replaced that for them already. I did quickly check to see if that was simply the problem, but it's not.

            First thing I checked was I2C_SMC_PWR_3V3_SCL and I2C_SMC_PWR_3V...

            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.
